Wear protective glasses and protective shoes when working.

DO NOT wear loose-fitting or torn clothing. Tie back and/or tuck in long hair. Remove all jewelry when working.

Before beginning any repair, disconnect the battery (negative [-] cable) and discharge any capacitors.

Put a DO NOT OPERATE tag in the operator's compartment or on the controls.

Allow the engine to cool before slowly loosening the coolant filler cap to relieve the pressure from the cooling system.

WARNING

Removing the fill cap on a hot engine can cause scalding coolant to spray out and burn you badly. If the engine has been in operation within the previ- ous 30 minutes, be very careful in re- moving the fill cap. Protect face, hands, and arms against escaping flu- id and steam by covering the cap with a large, thick rag. DO NOT try to re- move it until the surge tank cools down or if you see any steam or coolant es-

caping. In any situation, remove the cap very slowly and carefully. Be ready to back off if any steam or coolant be- gins to escape.

Always use wheel chocks or proper jack stands to support the vehicle or vehicle components before performing any service work. DO NOT work on anything that is supported only by lifting jacks or a hoist. Before resting a vehicle on jack stands, be sure the stands are rated for the load you will be placing on them.

Before removing or disconnecting any lines, fittings, or related items, relieve all pressure in the air, oil, fuel, and cooling systems. Remain alert for possible pressure when disconnecting any device from a system that contains pressure. High pressure oil or fuel can cause death or personal injury.

Always wear protective clothing when working on any refrigerant lines and make sure that the workplace is well ventilated. Inhalation of fumes can cause death or personal injury. To protect the environment, liquid

refrigerant systems must be properly emptied and filled using equipment that prevents the release of refrigerant gas. Federal law requires capturing and recycling refrigerant.

When moving or lifting any heavy equipment or parts, make sure to use proper techniques and assistance. Ensure all lifting devices such as chains, hooks, or slings are in good condition and are of the correct load capacity. Make sure all lifting devices are positioned correctly.

Corrosion inhibitors and lubricating oils may contain alkali. DO NOT get the substance in eyes and avoid prolonged or repeated contact with skin. DO NOT swallow. If ingested, seek immediate medical attention. DO NOT induce vomiting. In case of contact, immediately wash skin with soap and water. In case of harmful contact, immediately contact a physician. Always keep any chemicals OUT OF REACH OF CHILDREN.

materials. Always keep any chemicals OUT OF REACH OF CHILDREN.

When working on the vehicle, be alert for hot parts on systems that have just been turned off, exhaust gas flow, and hot fluids in lines, tubes, and compartments. Contact with any hot surface may cause burns.

Always use tools that are in good condition. Make sure you have the proper understanding of how to use the tools before performing any service work. Use only genuine replacement parts from PACCAR.

Always use the same fastener part number (or equivalent) when replacing items. DO NOT use a fastener of lesser quality if replacements are necessary. (e.g., DO NOT replace a SAE 10.9 grade with 8.8 grade fastener.)

Always torque fasteners and fuel connections to the required specifications. Overtightening or under-tightening can allow leakage.

Close the manual fuel valves prior to performing maintenance and repairs, and when storing the vehicle inside.

DO NOT perform any repair when impaired, tired, fatigued or after consuming alcohol or drugs that can impair your functioning.

Some state and federal agencies in the United States of America have determined that used engine oil can be carcinogenic and can cause reproductive toxicity. Avoid inhalation of vapors, ingestion, and prolonged contact with used engine oil.

DO NOT connect the jump starting or battery charging cables to any ignition or governor control wiring. This can cause electrical damage to the ignition or governor.

Coolant is toxic. If not reused, dispose of coolant in accordance with local environmental regulations.

CAUTION

Corrosive chemicals can damage the engine. DO NOT use corrosive chemi- cals on the engine. Failure to comply may result in equipment, or property damage.

California Proposition 65 Warning Diesel engine exhaust and some of

its constituents are known to the State of California to cause cancer, birth defects, and other reproductive harm.

The catalyst substrate located in the Diesel Particulate Filter (DPF) contains vanadium pentoxide, which has been determined by the State of California to cause cancer. Always wear protective clothing and eye protection when handling the catalyst assembly. Dispose of the catalyst in accordance with local regulations. If catalyst material gets into the eyes, immediately flood eyes with water for a minimum of 15 minutes. Avoid prolonged contact with skin.

Stop Engine Lamp

1 2

The stop engine warning lamp will illuminate, and an audible tone will sound, when a major engine problem exists. Your vehicle will be equipped with one of the indicators above, 1 or 2, depending on the engine model.

WARNING

If the Stop Engine warning lamp illumi- nates, it means you have a serious en- gine system problem. This should be considered an emergency. You should stop the vehicle as safely as possible and turn OFF the ignition. The vehicle must be serviced and the problem cor- rected before driving again. Failure to comply may result in death, personal injury, equipment or property damage.

For engines with the engine-protection shutdown feature enabled, the stop engine lamp will begin to flash 30 seconds before the engine automatically shuts down. The warning lamp alerts the operator to the impending shutdown.

The lamp will also illuminate when the DEF tank is almost empty or the soot level in the DPF is at full capacity. At this level warning, regeneration cannot be performed and engine power will be derated.

Engine may automatically shut down if the check engine lamp and stop engine lamp are illuminated and the operator does not correct the condition.

Engine Oil Pressure Lamp Turns On What to do if the engine oil pressure lamp turns on.

It is important to maintain oil pressure within acceptable limits. If oil pressure drops below the minimum psi a red warning lamp on the oil pressure gauge and the Stop Engine Lamp will come ON.

CAUTION

Continuing to operate your vehicle with insufficient oil pressure will cause seri- ous engine damage. Failure to comply may result in equipment or property damage.

If the oil pressure fails to rise within 10 seconds after the engine starts, stop the engine and determine the cause.

See Engine Oil Specification for the correct oil pressure ranges for your vehicle's engine.

If the oil pressure suddenly drops, or the audible alarm and engine oil pressure warning light come on while driving, do the following:

1. Slow down carefully. 2. Move a safe distance off the road

and stop. 3. Place the transmission in neutral (N)

and set the parking brake. (See Parking Brake Valve and Operating the Transmission in your vehicle Operator's Manual, for transmission

shifting and parking brake information.)

4. Turn OFF the engine. 5. Turn ON the emergency flasher and

use other warning devices to alert other motorists.

6. Wait a 1520 minutes to allow oil to drain into the engine oil pan, and then check the oil level. See Engine Oil Level.

7. Add oil if necessary. If the problem persists, contact an authorized PACCAR engine dealer as soon as possible.

Check Engine Lamp Turns On What to do if the check engine lamp turns on.

Or

Check Engine Lamp - Turns on when a problem exists, but the vehicle can still be safely driven. Vehicle should be serviced to correct the problem but the situation should not be considered an emergency.

The lamp will also illuminate when a DPF regeneration or addition of diesel exhaust fluid (DEF) is required. For PACCAR PX Engines, this icon may also illuminate if the crankcase breather element needs attention. Another function of the check engine lamp is to warn the operator of an impending idle shutdown. When the idle shutdown timer is 30 seconds from expiring, the ECM begins flashing the check engine warning lamp once per second. When the timer expires, the ECM will turn off the warning lamp and shut down the engine.

Engine is Overheating The cooling system may overheat if the coolant level is below normal or if there is

sudden loss of coolant. Follow these steps if the engine is overheating.

CAUTION

The cooling system may overheat if the engine coolant is at the minimum level. A sudden loss of coolant, caused by a split hose or broken hose clamp could also lead to an overheat condition. Always inspect to ensure hoses and clamps are not cracked, worn, or loose. Failure to comply may result in equipment or property dam- age.

NOTE

The system may also temporarily over- heat during severe operating condi- tions such as:

Climbing a hill on a hot day Stopping after high-speed/high-

load driving

Debris blocking air flow through the cooling module (radiator)

If the engine coolant temperature warning lamp comes on and the audible alarm sounds showing an overheat condition, or if you have any other reason to suspect the engine may be overheating, DO NOT TURN OFF THE ENGINE unless a low water warning device indicates a loss of coolant. Follow these steps:

Follow these steps if the engine coolant temperature is rising, or the temperature is already above normal, and there are no other warning alarms displayed in the instrument cluster.

1. Reduce engine speed, or stop. When stopped, place the transmission in neutral (N) and set the parking brake. Keep the engine running. See the vehicle operator's manual for instructions on transmission shifting and parking brake information.

WARNING

To reduce the chance of person- al injury, vehicle damage and/or death from overheated engines, which can result in a fire, never leave the engine idling without an alert driver present. If the en- gine should overheat, as indicat- ed by the engine coolant temper- ature light, immediate action is required to correct the condition. Continued unattended operation of the engine, even for a short time, may result in serious en- gine damage or a fire. Failure to comply may result in death, per- sonal injury, equipment or prop- erty damage.

WARNING

Removing the fill cap on a hot engine can cause scalding cool- ant to spray out and burn you badly. If the engine has been in operation within the previous 30 minutes, be very careful in re- moving the fill cap. Protect face,

hands, and arms against escap- ing fluid and steam by covering the cap with a large, thick rag. DO NOT try to remove it until the surge tank cools down or if you see any steam or coolant escap- ing. In any situation, remove the cap very slowly and carefully. Be ready to back off if any steam or coolant begins to escape.

NOTE

Keep the engine running at idle speed unless a warning icon turns on that requires the engine to be shut off.

2. Check to ensure the Oil Pressure Gauge reads normal.

3. Make sure the engine fan is turning by switching the Engine Fan Switch from AUTO to MAN (Manual).

4. Increase the engine speed to about one-half of full operating speed, or 1,100 to 1,200 rpm, maximum for 2 or 3 minutes.

5. Return the engine speed to normal idle. Monitor the engine temperature. After the temperature returns to

normal, allow the engine to idle 3 to 5 minutes before shutting it off. This allows the engine to cool gradually and uniformly.

6. If overheating came from severe operating conditions, the temperature should have cooled by this time. If it has not, stop the engine and let it cool before checking to see if the coolant is low.

7. Be sure the vehicle is parked on level ground or the readings may be incorrect. Check the coolant level at the cooling module surge tank.

Check the coolant level after each trip when the engine has cooled. The coolant level should be visible within the surge tank. Add coolant if necessary.

you may see it when the engine grid heater is on and needs some time to warm up. (PACCAR PX and Cummins ISL engines)

NOTE

Some engines are equipped with an engine starting motor protection fea- ture. If the starting motor is engaged for 30 or more seconds, without the engine starting, the starter will be locked out from operating, allowing for proper cooling of the starting motor. During this time, the 'Wait-To-Start' lamp will flash for 2 minutes. Once the lamp stops flashing, the starting motor will be allowed to function.

Engine Braking System Information on using the engine braking system.

An engine compression brake is standard on the PX-9 engines. Optionally, this engine may be equipped with an exahust brake. When activated, these devices create a braking effect on the drive wheels. Because it can help keep your vehicles brakes from overheating, it can save wear

and tear on the service brakes. However, the engine compression or exhaust brake is not an emergency brake or the primary vehicle brake.

WARNING

DO NOT operate the engine compres- sion brake when driving/operating your vehicle bobtail or with a loaded or un- loaded trailer on road surfaces with poor traction (wet, icy, or snow cov- ered roads) or in heavy traffic. There may not be enough weight on the rear axle to provide traction. Braking caused by the normal operation of the engine compression brake could cause you to lose control of the vehi- cle, resulting in an injury accident. Make sure the engine brake is switch- ed "OFF" when bobtailing or with an unloaded trailer. Failure to comply may result in death, personal injury, equip- ment or property damage.

WARNING

The service brakes must be used in an emergency. The engine compression

brake alone might not stop the vehicle fast enough to prevent an accident. The engine compression brake is NOT intended as the primary brake for the vehicle, nor is it an emergency brake. The engine compression brake only helps the service brakes by using en- gine back pressure to slow the drive- train. Use the service brakes for quick stops. You could be seriously injured if you relied only on the engine compres- sion brake to stop the vehicle in an emergency. Failure to comply may re- sult in death, personal injury, equip- ment or property damage.

CAUTION

DO NOT operate the engine brake un- til the engine oil temperature is above 86F (30C). Operation below 86F (30C) could cause severe damage to the engine. Idle the engine four mi- nutes at approximately 1,000 rpm to warm the engine before activating the engine brakes.

ENGINE OPERATION - Operating Instructions

18 Y53-1185-1E1 (04/16/18)

NOTE

If your vehicle is equipped with anti- lock brakes (ABS), operation of the compression brake (if turned ON) may be interrupted if the ABS system de- tects wheel-slip due to operation on slippery surfaces.

Ideally (on normal road surfaces), you should slow your vehicle with the compression brake (where permitted by law) and use the service brakes only for stopping completely. Operating this way will greatly prolong the life of the service brakes.

Compression Brake Proper use of engine compression brakes.

With the compression brake switch ON, the brake automatically creates its braking effect when you remove your foot from the accelerator pedal.

The brake switch is located on the accessory dash panel. It controls whether the brake is ON (ready to slow the vehicle down) or OFF (no braking action).

1. Do not use the engine compression brake to slow the vehicle down when you are bobtailing or pulling an empty trailer.

2. Make sure the brake is OFF before starting the engine.

3. After the engine is started, warmed up and you are ready to get under way, turn the engine compression brake switch ON for added braking effect.

NOTE

If your vehicle is equipped with the Eaton Vorad system, oper- ation of the compression brake may be automatically activated.

Compression Brake Controls Using the compression brake controls.

There are two switches on the dash panel that control the engine compression brake. A master switch turns the system ON or OFF. A second switch, located next to the master switch, controls the braking effect. This switch allows you to choose

progressively stronger braking to slow the vehicle down.

Engine compression brake controls include:

ON/OFF switch Three-position selector switch Clutch switch Throttle sensor Service brake pressure switch Eaton Vorad Anti-Lock Braking

System

Engaging conditions for the engine compression brake:

Engine speed must be above 1,000 rpm.

Coolant temperature must be above 59F (15C).

Deactivation conditions for the engine compression brake:

Accelerator pedal is depressed. Clutch pedal is depressed. Engine speed falls below 800 rpm. ABS control is active. ECM recognizes a system problem.

CAUTION

Operating the engine with a compres- sion brake that will not automatically deactivate (i.e. when the dash switch is OFF, clutch pedal is depressed or throttle is applied) will cause severe in- ternal engine damage. Do not operate the engine if the compression brake will not deactivate. Failure to comply may result in equipment or property damage.

Engine Compression Brake Level Switch Operation How to operate the compression brake.

There are two switches that control your vehicles engine compression brake. One switch turns the system ON/OFF and the second switch controls the braking level. These switches are located on the dash switch panel.

For the three-position engine compression brake level switch, there will be 100 percent engine braking when the switch is in the up (HIGH) position. In the middle (MEDIUM) position, there will be 66

percent engine braking. In the down (LOW) position there will be 33 percent engine braking.

With the compression brake switch ON, the compression brake will be engaged when the service brake is applied. If the cruise control is operated in conjunction with the compression brake, the compression brake will engage to maintain the cruise set speed.

Combustible Vapors

1 Do Not Use Combustible Gas in Turbo

NOTE

Numerous safety devices (i.e. engine shutoff devices) are available to mini- mize the risk of engine overspeeding caused by combustible vapors being ingested into the air intake system.

PACCAR recommends the installation of an air intake shutoff device or a similar safety device to minimize the risk of overspeeding, as can occur when the vehicle is being operated in a combustible environment, such as from a fuel spill or gas leak.

WARNING

Combustible vapors near the air intake system could be ingested into the en- gine, causing the engine to suddenly accelerate and overspeed. This condi- tion could result in operator losing con- trol of the vehicle if an unexpected in- crease in engine rpm occurs. Combus- tible vapors could also cause a fire.

DO NOT operate your vehicle in an area where combustible chemicals or vapors may be present. Failure to comply may result in death, personal injury, equipment or property damage.

NOTE

IT IS THE RESPONSIBILITY OF THE OWNER AND OPERATOR TO OPER- ATE THE VEHICLE IN A SAFE ENVI- RONMENT.

NOTE

If the engine is running, do not in- crease engine speed (rpm) or operate the vehicle until the low oil pressure warning lamp turns off.

CAUTION

Engaging the starter motor for more than 30 seconds in any five minute pe- riod may cause it to overheat and can damage the starter.

If starter is engaged continuously for 30 seconds, you must wait five minutes before trying to start the engine to allow the starter motor to cool down.

With the key in the ON position, the engine warning lamps will come on momentarily and then go out. The engine warning lamps include:

Check engine lamp; amber in color.

Stop engine lamp; red in color.

Normal Starting Procedure Steps for starting the engine in normal temperatures.

Allow the Wait-To-Start warning lamp to turned off. Engine Wait-To-Start Lamp on page 17

Follow this engine starting procedure when the outside temperature is above 50F (10C).

1. Ensure the parking brake is set ON and the transmission shift lever is in neutral. For automatic transmissions, be sure the shift lever is in the neutral position (N). For automatic transmissions that have park (P) position, place the shift lever in park.

2. With the accelerator pedal in the idle position, turn the ignition key to the START position to start the engine.

3. If the engine does not start after 10 seconds, release the key. Wait an additional 10 seconds to allow the starter motor to cool, then try staring the engine again.

4. Once the engine has started, wait for the oil pressure to rise, and the low oil pressure warning lamp to turn off, before increasing rpm.

After the engine is started, the voltmeter, if equipped, may show a gauge fluctuation under certain engine temperature conditions (both warm and cold). This cycling operation is caused by the post- heat cycle of the intake manifold heater system. The number of cycles and the length of the cycling operation is controlled by the engine control module. The cycling action will cause temporary dimming of the headlamps, interior lamps, and other vehicle electrical accessories.

Cold Weather Starting Steps for starting the engine in cold temperatures.

Allow the Wait-to-Start warning lamp to turn off. Engine Wait-To-Start Lamp on page 17

Follow this engine starting procedure when the outside temperature is below 50F (10C).

CAUTION

To reduce the possibility of damage to the lubricating oil pan, due to the ma- terials used in the manufacture of the lubricating oil pan, under no circum- stances should an external heat source be applied directly or indirectly to the lubricating oil pan.

1. Follow the Normal Starting Procedure on page 23 .

Refer to the vehicle operator's manual instructions for any additional cold weather starting procedures.

2. If starting a cold engine, slowly increase the engine speed. This provides adequate lubrication to the bearings and gives ample time to allow the oil pressure to stabilize.

CAUTION

The use of starting aids, such as ether, may result in damage to the engine and aftertreatment system.

3. For coolant temperatures below 150F (70C), use a low gear and drive at moderate engine speed until the engine coolant has reached operating temperature. Do not let the engine idle longer than necessary. If the vehicle cannot be driven, an elivated idle speed may be used instead to warm the engine.

CAUTION

Do not operate the engine at low idle for long periods of time when the coolant temperature is below the normal operating range. This could result in the following:

Fuel dilution of the lubri- cating oil

Carbon buildup in the combustion chamber

Sticking of the valves in the cylinder head

Reduced performance Damage to aftertreatment

components

Starting Procedure After Extended Shutdown or Oil Change Guideline on starting the engine after prolonged shutdown or oil change.

After extended shutdown or an oil change follow the Normal Starting Procedure on page 23 .

The engine will run at idle only until the minimum oil pressure is detected by the ECM. It can take more cranking time to start the engine after an extended shut down or oil change.

Operating the Engine After the engine starts:

Monitor the oil pressure and coolant temperature gauges frequently. Refer to Engine Oil Capacities and Pressures on page 45 and Engine Coolant Specifications on page 50 for recommended operating pressures and temperatures. Shut off the engine if any pressure or temperature does NOT meet the specifications.

ENGINE OPERATION - Operating Instructions

24 Y53-1185-1E1 (04/16/18)

Continuous operation with engine coolant temperature above or below the engine coolant temperature specifications listed in Engine Coolant Specifications on page 50 can damage the engine.

Engine Operating Range Information on operating the engine at proper rpm.

Proper Engine Operating Range

1. Full Throttle rpm 2. Peak Torque

CAUTION

Operating the engine at full throttle be- low peak torque will shorten engine life to overhaul, can cause serious engine damage, and is considered engine abuse. DO NOT operate the engine at full throttle operation below peak tor-

que rpm for more than 30 seconds. Failure to comply may result in equip- ment or property damage.

PACCAR engines are designed to operate at full throttle under momentary conditions down to peak torque engine speed. This is consistent with recommended operating practices.

CAUTION

Operating the engine beyond the max- imum engine speed can cause severe engine damage. Use proper operating techniques for the vehicle to prevent engine overspeed. See Engine Speci- fications for maximum engine speed. Failure to comply may result in equip- ment or property damage.

Extended Idling

CAUTION

Prolonged periods of idling can result in lower than optimal engine/transmis- sion operating temperatures which could cause increased rates of wear. An idle shutdown feature (available on PACCAR engines) can be program- med to shut the engine down after a period of low idle operation with no driver activity. A flashing warning lamp will inform the driver of an impending shutdown. Failure to comply may re- sult in equipment or property damage.

CAUTION

If the truck is equipped with power take off (PTO) equipment, the engine shutdown system can be deactivated when the PTO is operational; however, engine idle periods should not exceed five minutes whenever possible. Fail- ure to comply may result in equipment or property damage.

Long periods of idle-time (3 hours or more) may accelerate the build up of soot in the diesel particulate filter (DPF), especially in cold weather. The system will illuminate the DPF warning light on the instrument cluster and a message on the Driver Information Display to indicate that the DPF requires regeneration. This is not a problem with the vehicle; however, it indicates that the driver needs to start a parked DPF regeneration to prevent equipment damage caused by soot build up. If the DPF lamp turns ON and the driver is prompted to through driver notifications, perform a parked DPF Regeneration.

CAUTION

If you ignore the warning lamp and do not initiate regeneration at the soon- est, safest possible time, the DPF will become increasingly clogged with soot and can lead to severe engine derate. Failure to comply may result in equip- ment or property damage.

Extended engine idling may also increase hydrocarbon deposits and moisture in the DPF. The engine will increase rpm automatically, regardless if the DPF lamp is

on or off, to remove these hydrocarbon deposits and moisture. The engine speed will remain elevated for 20-60 minutes. If necessary, the rpms may be lowered by briefly depressing the throttle, clutch, or brake pedal. If the driver cancels the automatic cycle using the pedals, the system will restart the cycle 10 minutes later with increased rpm until all of the deposits are removed from the DPF. If the vehicle cannot perform an automatic cycle, the driver may be prompted with message to regenerate the DPF with a "Do Not Drive" message. The driver must complete a regeneration before driving. If the "Do Not Drive" message is ignored and a DPF regeneration is not fully completed before driving, there is a high possibility of equipment damage.

If an engine must idle for an extended period of time, idle the engine at the lowest rpm that maintains the engine coolant at 150F (70C), or above.

ENGINE OPERATION - Operating Instructions

26 Y53-1185-1E1 (04/16/18)

1

CAUTION

DO NOT idle the engine for excessive- ly long periods. Long periods of idling, more than 10 minutes, can cause poor engine performance.

Following these guidelines will help reduce engine wear during idling and the frequency of DPF regenerations.

Engine Shutdown Prevent engine damage by following these shutdown precautions.

NOTE

DO NOT shut off the engine immedi- ately. A hot engine stores a great amount of heat and it does not cool down immediately after it is shut off. Always cool the engine down before shutting it off. You will greatly increase its service life.

Idle the engine at 1,000 rpm for four minutes. Then low idle for 30 seconds

before shutdown. This will allow circulating coolant and lubricating oil to carry heat away from the cylinder head, valves, pistons, cylinder liners, turbocharger, and bearings. This way you can prevent engine damage that may result from uneven cooling.

NOTE

For engines equipped with an elec- tronic control module (ECM), ensure the ignition switch is turned OFF for a minimum of 100 seconds prior to dis- connecting the continuous (unswitch- ed) battery power supply. If the un- switched battery power supply is dis- connected in less than 100 seconds after the ignition switch is turned OFF, active fault codes and incorrect ECM information may occur.

CAUTION

Failure to follow the correct shutdown procedure may result in damage to the turbocharger and shorten the turbo- charger life.

Electromagnetic Interference Information on electromagnetic interference (EMI).

If not installed correctly, some vehicle accessories (CB radios, mobile transmitters, etc.) can generate and use radio frequency energy that may cause electromagnetic interference (EMI) between the accessory and the electronically controlled fuel system. Under these conditions, PACCAR is not liable for any performance problems with either the fuel system or the accessory. EMI is not considered by PACCAR to be an engine failure and therefore is not warrantable.

System EMI Susceptibility PACCAR products are designed and tested for minimum sensitivity to incoming electromagnetic energy. The fuel system EMI susceptibility has been designed with a high tolerance against EMI and in most normal circumstances, if not all, electromagnetic energy-emitting devices that meet the Federal Communications Commission legal requirements should cause no interference.

System EMI Radiation Levels Electronic components are required to pass various PACCAR and industry EMI specifications. Our testing has shown that when the engine is properly installed and maintained, it will not interfere with properly installed onboard communication equipment.

If any interference condition is noticed, follow these suggestions to reduce the amount of EMI:

1. Locate the accessory receiving antenna further away.

2. Check with the accessory supplier representative in your area to:

Accurately calibrate the accessory for proper frequency, power output, and sensitivity.

Determine the optimum antenna location by obtaining antenna reflective energy data measurements.

Ensure that the optimum antenna type and mounting arrangement is being used.

Ensure the accessory equipment is properly constructed for

maximum filtering to reject incoming electromagnetic noise.

Operating on Level and Dry Pavement Tips for driving on level and dry roads.

WARNING

DO NOT use the engine brake when operating on road surfaces with poor traction (such as wet, icy, or snow cov- ered roads or gravel). Retarders can cause the wheels to skid on a slippery surface. You could lose control of the vehicle and/or jackknife if the wheels begin to skid, resulting in an accident. Failure to comply may result in death, personal injury, equipment or property damage.

WARNING

DO NOT operate the engine compres- sion brake when driving/operating your vehicle bobtail or with a loaded or un- loaded trailer on road surfaces with

poor traction (wet, icy, or snow cov- ered roads) or in heavy traffic. There may not be enough weight on the rear axle to provide traction. Braking caused by the normal operation of the engine compression brake could cause you to lose control of the vehi- cle, resulting in an injury accident. Make sure the engine brake is switch- ed "OFF" when bobtailing or with an unloaded trailer. Failure to comply may result in death, personal injury, equip- ment or property damage.

For operation on dry and relatively flat surfaces, when greater retarding power is not required, put the two-position selector switch in the "LOW" position.

For operation on dry pavement when maximum retarding power is required, put the three-position selector switch in the "HI" position.

Operating on Grades and Dry Pavement Tips for driving on grades and dry roads.

WARNING

The engine brake is not intended as the primary brake for the vehicle, nor is it an emergency brake. The service brakes must be used in an emergency. Relying solely on the engine brake to stop the vehicle in an emergency could cause an accident and lead to personal injury. The engine brake only helps the service brakes by using pressure to slow the drive train. You

must use the service brakes for quick or emergency stops. Failure to comply may result in death, personal injury, equipment or property damage.

"Control speed" is the speed at which the forces pushing a vehicle down a grade are equal to the forces holding it back.

DO NOT use the engine brake when operating on road surfaces with poor traction (such as wet, icy, or snow cov- ered roads or gravel). Retarders can cause the wheels to skid on a slippery surface. You could lose control of the

vehicle and/or jackknife if the wheels begin to skid, resulting in an accident. Failure to comply may result in death, personal injury, equipment or property damage.

CAUTION

The engine ECM maintains a record of maximum rpm. Exceeding the maxi- mum rpm will be considered driver abuse and will affect the engine war- ranty. See Engine Spcifications.

WARNING

DO NOT use an exhaust brake when driving bobtail or with an unloaded trailer. There may not be enough weight on the rear axle to provide trac- tion. This could cause a loss of control and jackknife resulting in an injury ac- cident. Make sure the exhaust brake is switched OFF when bobtailing or with an unloaded trailer. Failure to comply may result in death, personal injury, equipment or property damage.

CAUTION

Never exceed governed engine speed because engine damage can occur. Operating engine beyond the gov- erned speed causes additional strain on valve train and internal engine com- ponents. Operate the engine within governed engine speed.

NOTE

Once you have determined what the safe speed is for your vehicle, operate the engine brakes with the transmis- sion in the lowest gear that will not cause the engine speed to exceed the rated engine speed. The optimum braking power of the engine brakes is reached at rated engine speed. Cor- rect gear selection, therefore, is criti- cal.

The selector switch can be used to vary braking power as road conditions change.

Vehicle service brakes must be used when additional braking power is required.

Slow Down Around Curves

The engine brake is NOT intended as the primary brake for the vehicle, nor is it an emergency brake. The engine brake only helps the service brakes by using pressure to slow the drivetrain. Use the service brakes for quick stops.

Braking Truck on Grade

WARNING

DO NOT drive with frequent or contin- uous use of the service brakes. This can overheat the brakes and result in excessive lining wear, increased stop- ping distances, possibly an accident and may lead to personal injury. Be- fore descending a steep grade, shift to a lower gear, keep the vehicle speed low, and avoid continuous application to the brakes. Failure to comply may result in death, personal injury, equip- ment or property damage.

Tips for Operation on Slick Roads

WARNING

To reduce the possibility of personal injury or property damage, always al- low for extra distance between your vehicle and other objects when using the service brakes or engine brakes on slick roads.

The operation of any vehicle is difficult to predict on slick roads. The first 10 to 15 minutes of rainfall are the most dangerous, as road dirt and oil mixed with rain create a very slippery surface.

WARNING

DO NOT use any of the vehicles re- tarders in any situation that requires an immediate stop and/or in situations of poor traction (such as wet, icy or snow covered roads). Trying to use the retarder instead of the service brakes may cause a loss of vehicle control, which may result in an acci- dent involving death or personal injury.

When driving on slick roads, start with the ON/OFF switch in the OFF position and the two-position selector switch in the LOW position. If your tractor is equipped with a twin-screw rear axle, position the power divider switch in the unlocked position. Remove your foot from the accelerator pedal to make sure the vehicle will maintain traction with the retarding power of the engine alone. If the vehicle drive wheels begin to skid or if there is a fishtailing motion, DO NOT activate the engine brakes. If traction is maintained using the retarding power of the engine alone and more braking power is required, switch the two-position selector switch to the LOW position and activate the engine brakes by switching the ON/OFF switch to the ON position. If the vehicles drive wheels begin to skid or there is a fishtailing motion, switch the ON/OFF switch to the OFF position. If traction is maintained when the engine brakes are activated and more braking power is required, move the two-position selector switch to the HI position. Again, if the vehicle has lost traction or if there is a fishtailing motion, switch the ON/OFF switch to the OFF position. DO NOT attempt to use the engine brakes in the HI position.

Chapter 2 | Engine Maintenance

Maintenance Requirements

Engine Maintenance Introduction and important maintenance requirements.

PACCAR recommends that the engine be maintained according to the maintenance schedule in this section.

If the engine is operating in ambient temperatures below 0F (-18C) or above 100F (38C), perform maintenance at shorter intervals. Shorter maintenance intervals are also required if the engine is operated in a dusty environment or if frequent stops are made.

Some of these maintenance procedures require special tools or must be completed by qualified personnel. Contact your local PACCAR authorized repair location for detailed information.

If your engine is equipped with a component or accessory not manufactured by PACCAR Inc, refer to the component

manufacturer's maintenance recommendations.

WARNING

Never idle your vehicle for prolonged periods of time if you sense that ex- haust fumes are entering the cab. In- vestigate the cause of the fumes and correct it as soon as possible. If the vehicle must be driven under these conditions, drive only with the windows open. Failure to repair the source of the exhaust fumes may result in death, personal injury, equipment or property damage.

WARNING

Exhaust fumes from the engine con- tain carbon monoxide, a colorless and odorless gas. DO NOT breathe the en- gine exhaust gas. A poorly maintained, damaged or corroded exhaust system can allow carbon monoxide to enter the cab. Entry of carbon monoxide into the cab is also possible from other ve- hicles nearby. Failure to properly main- tain your vehicle could cause carbon

monoxide to enter the cab, resulting in death or personal injury.

Cleaning the Engine Engine cleaning precautions.

When cleaning the engine, follow the instructions from the vehicle manufacturer operator's manual and observe all environmental protection regulations.

CAUTION

DO NOT direct water onto electrical components, plug connectors, seals or flexible hoses on the engine. Water may enter the part causing electrical damage or contaminating the engine oil. To prevent damage to engine com- ponents, keep the water moving at all times while cleaning the engine. Fail- ure to comply may result in equipment damage.

Coolant Level Daily and refueling maintenance check for engine coolant level.

Replacement or top up coolant should have the same antifreeze concentration and corrosion inhibitor content as the original coolant in the cooling system. If operating in sub-freezing conditions, a 60/40 mix of antifreeze and distilled water may be substituted.

ENGINE MAINTENANCE - Maintenance Requirements

Y53-1185-1E1 (04/16/18) 35

2

Always dilute antifreeze to the correct concentration based on freeze protection before adding it to the cooling system. Adding or using 100% antifreeze in a cooling system may result in cooling system plugging and overheating problems.

This procedure should be followed as part of daily and refueling maintenance checks.

Perform the following steps to check the coolant level:

1. Check that vehicle is a on a level surface.

2. Ensure engine has not been run for several hours.

CAUTION

Due to thermal expansion the coolant level CANNOT be checked if the coolant is above ambient temperature or the en- gine has not completely cooled. The coolant level indicated on a warmed system will be inaccu- rate and can lead to low coolant conditions during cold-starts.

3. Check coolant level. It should be visible through the clear plastic surge tank.

4. Add coolant as necessary until proper level is reached.

NOTE

The pressure cap (on the side of the surge tank) should NEVER be removed. The fill cap (On the top, not the side of the surge tank) is the correct fill point.

Aftertreatment Exhaust Piping Daily and refueling maintenance check for aftertreatment exhaust piping.

This procedure should be followed as part of daily and refueling maintenance checks.

1. Inspect for cracks. 2. Inspect for clearance to other

components (i.e. electrical harnesses, etc.).

3. Inspect hose/pipe condition deterioration/signs of leaking.

Air Intake Piping Daily and refueling maintenance check for engine air intake piping.

This procedure should be followed as part of daily and refueling maintenance checks.

1. Inspect hose/pipe condition deterioration/signs of leaking.

2. Inspect hose clamps for tightness and pinching/cutting of hoses.

3. Inspect clearance to other components.

4. Check air restriction gauge.

How to Drain Moisture from Air Tank

Filter Specifications Use of non-genuine filters.

PACCAR is not responsible for problems caused by non-genuine filters that do not meet PACCAR performance or durability requirements.

Contact your local PACCAR authorized repair location for specific part numbers.

Fleetguard filters are standard on new PACCAR engines. PACCAR recommends their use.

Fleetguard products meet all PACCAR test standards to provide the quality filtration

necessary to achieve the engine's design life. If other brands are substituted, the purchaser should ensure the filter specification meet or exceed the Fleetguard specifications.

CAUTION

Use of non-genuine oil filters can cause severe engine damage.

Engine Lubricating Oil Recommendations and Specifications

PACCAR engine oil type, viscosity, and additives.

A major factor in maintaining engine performance and durability is the proper use of quality engine lubricating oils used in conjunction with the appropriate oil drain and filter change intervals. Attempting to extend the oil and filter change interval beyond the manufacturers recommendations may decrease engine

life due to factors such as corrosion, deposits, and wear.

See Engine Lubrication and Filter Intervals to determine which oil drain interval to use for an application.

NOTE

It is the operators responsibility to fol- low these recommendations to ensure that the engine warranty is not affect- ed.

The primary PACCAR recommendation is for the use of SAE 10W-30 API CK-4 or CJ-4 multigrade lubricating oil for normal operation at ambient temperatures above 5F (-15C). For ambient temperatures below 5F (-15C) SAE 5W-30 may be used, provided it meets API CK-4 or CJ-4

oil specifications and biodiesel or biodiesel blended fuel is not used as fuel for the engine. Use of 0W-40 and 0W-30 synthetic oils that meet API CK-4 or CJ-4 certification can be used in operations where the ambient temperature never exceeds 32F (0C). 0W-40 and 0W-30 oils do not offer the same level of protection against fuel dilution as do higher multigrade oils. Higher cylinder wear can be experienced when using 0W-40 or 0W-30 oils in highload situations. Using a multigrade oil helps improve engine cranking in low-temperature conditions, reduces deposit formation and increases engine durability. The use of a fuel economy oil such as an API FA-4 oil is not approved for this engine.

NOTE

If the type/oil capacity of each lubricat- ing oil pan is not known:

Contact a PACCAR Authorized Repair Location

Determine the capacity of the oil pan option for the engine being serviced by using QuickServe Online and the engine serial num- ber.

Fill the lubricating oil pan to the smallest oil pan capacity listed for the engine being serviced. Then add 1 US qt (0.95 liters) of oil at a time until it reaches the high mark on the dipstick. Record the num- ber of quarts/liters added, so the capacity is known the next time the oil is drained.

CAUTION

A sulfated ash limit of 1.85 percent has been placed on all engine lubricating oils recommended for use in PACCAR engines. Higher ash oils can cause valve and/or piston damage and lead to excessive oil consumption. Failure to comply may result in equipment damage.

CAUTION

The use of a synthetic-base oil does not justify extended oil change inter- vals. Extended oil change intervals can decrease engine life due to factors

such as corrosion, deposits, and wear. Failure to comply may result in equip- ment damage.

Additional information regarding lubricating oil availability throughout the world is available in the EMA Lubricating Oils Data Book for Heavy-Duty Automotive and Industrial Engines. The data book can be ordered from: Engine Manufacturers Association, Two North LaSalle Street, Chicago, IL 60602; (312) 827-8733, ( www.enginemanufacturers.org).

Aftermarket Oil Additive Usage PACCAR does not recommend the use of aftermarket oil additives. Today's high- quality engine lubricating oils are very sophisticated. Most oils already contain

precise amounts of additives blended into the lubricating oil to meet stringent performance requirements.

These oils meet performance characteristics that conform to the lubricant industry standards and are sufficient protection when used according to the recommendations. Aftermarket lubricating oil additives are not necessary to enhance engine oil performance and may in some cases reduce the oil's capability to protect the engine.

Engine Lubrication and Filter Intervals

Oil change intervals for normal and severe duty applications.

See the following table to determine the maximum recommended oil change and oil filter change intervals in miles (kilometers)/ hours or months, whichever comes first.

Replace the fuel filters (pressure and suction side) at the same interval as the oil and oil filter are changed.

NOTE

Idle time must be factored into calcu- lating average vehicle speed.

The intervals are based on the vehicles average speed/miles per hour (mph) (Includes idle time). Locate your vehicles average vehicle speed/mph in the first column to determine the oil change/filter change interval to use. If the vehicle is equipped with an hour meter, it is acceptable to use the engine hours listed

for the oil change and oil filter change interval.

If the average vehicle speed/mph is unknown and the vehicle is not equipped with an hour meter:

1. See the "Typical Application(s)" column. Use the lowest interval listed for your application.

2. Connect an electronic service tool. The electronic service tool can provide the average vehicle speed recorded by the engine control module (ECM). This can be done at a PACCAR Authorized Repair Location.

Cummins Inc. bases the oil drain specifications on duty cycle and oil contamination. This contamination occurs in all engines, at varying rates, regardless of the drain interval.

Maintaining the correct oil and filter change interval is a vital factor in preserving the integrity of an engine. Lubricating oil filters must be changed when the oil is changed.

Cooling System Maintenance

Information about concentration and condition of coolant, including filter.

The cooling system in your vehicle was factory filled with extended life coolant that meets or exceeds all ASTM D6210 and

Caterpillar EC-1 requirements. PACCAR recommends only using a 50/50 mixture of distilled water and ELC when cooling system service is required. A 50/50 mixture of ELC and distilled water will provide freeze protection down to 34F (37C), which is adequate for most locations in North America. For extremely cold operating conditions, a 60/40 mixture (coolant/water ratio) can be used to provide freeze protection down to -62F (-52C).

Unless otherwise optioned, factory fill coolant is an ethylene glycol, nitrited organic acid technology (NOAT) extended life coolant (ELC) formulation at a 50/50 coolant-to-distilled water mixture. The factory fill exceeds ASTM D6210 and Caterpillar EC-1 requirements. Maintaining coolant chemistry and freeze protection is

critical to engine and cooling system component health and longevity.

WARNING

Coolant is toxic. DO NOT get the fluid in eyes. If contact occurs, flood eyes with large amounts of water for 15 mi- nutes. Avoid prolonged or repeated contact with skin. In case of contact, immediately wash skin with soap and water. DO NOT take internally. If swal- lowed, seek immediate medical atten- tion. DO NOT induce vomiting. Failure to comply may result in death, person- al injury, equipment or property dam- age.

CAUTION

The engine cooling system has very specific maintenance and inspection requirements. Failure to follow require- ments can damage the engine. Engine damage can include but is not limited to freezing, boiling, corrosion, pitted cylinder liners. This information is found in the engine manufacturers owners manual. It is the owners re- sponsibility to follow all requirements listed in the engine manufacturers owners manual.

NOTE

Coolant is harmful to the environment. Unused coolant must be stored as a toxic hazardous material in leakproof containers. Used coolant must be processed as industrial chemical waste. Please follow HAZMAT guide- lines with both used and unused cool- ants.

CAUTION

Use of non-genuine coolant filters can cause severe engine damage.

Concentration Check the level of freeze/boilover protection, which is determined by the glycol concentration. Use a glycol refractometer to determine glycol level. Add coolant to obtain the coolant/water ratio required to provide the protection you need. A 50/50 mix of coolant and water is adequate for most applications. For extremely cold operating conditions, the ratio can be adjusted to a higher concentration of coolant.

NOTE

Maximum recommended ELC concen- tration is 60% ELC and 40% water by volume (a 60/40 coolant mixture). The minimum recommended concentration is 40%.

Condition Perform a visual inspection of the coolant. It should have no cloudiness or floating debris. Determine the chemical inhibitor concentration level by using an extended life coolant specific test kit or test strips. Inhibitor concentration level determines corrosion protection. If you are concerned about possible coolant quality, contamination, or mechanical problems, submit a coolant sample for analysis. Improper maintenance may cause coolant

degradation and could result in damage to the cooling system and engine components. Consult your dealer or the coolant manufacturers representative for recommended extended life coolant test kits, test strips, and laboratory sample procedures.

Coolant Extender Add extended life coolant extender, if necessary, according to the corrosion inhibitor concentration required. DO NOT add coolant extender to nitrite-free coolant.

Checking Coolant Level Check the coolant level daily. See Coolant Level on page 35 .

CAUTION

When adding coolant, avoid mixing dif- ferent brands and formulations. If the coolant is mixed with more than 25% of a different formulation (for example, mixing OAT and NOAT coolants), en- gine corrosion damage could occur. If mixing exceeds 25% of total system volume, it is recommended to flush

and refill the system completely with one type of coolant.

Cooling System Sealing Additives and Soluble Oils

OK

1. Do not use soluble oils or sealing additives.

CAUTION

The use of sealing additives or soluble oils in the cooling system can cause damage to the engine. These additives can plug various areas of the radiator, EGR system and oil cooler. The plug- ging of the cooling system can hamper heat transfer, causing internal engine damage. DO NOT use sealing addi- tives or soluble oils in the cooling sys- tem. The use of sealing additives can:

Build up in coolant low-flow areas Plug the radiator and oil cooler Damage the water pump seal Damage heat transfer surfaces Damage seals and hoses Corrode brass and copper

Failure to comply may result in equip- ment or property damage.

Extended Life Coolant

Information on using Extended Life Coolant (ELC).

Perform these maintenance procedures according to the Preventative Maintenance Schedule.

Conduct coolant maintenance checks including freeze point, pH, nitrite and carboxylate tests at least twice annually to maintain engine protection.

Nitrited Extended Life Coolant For nitrited formulations (NOAT), a heavy- duty extended life coolant that meets ASTM D6210 and Caterpillar EC-1 specifications must be used.

The change interval for extended-life coolant containing nitrite and molybdate is 750,000 miles (1,200,000 km) or 12,000 hours of on-road use (8 years or 15,000 hours of off-highway use) on initial fill with no extender added. The change interval is 1,000,000 miles (1,600,000 km)/20,000 hours/8 years with an extender addition at 500,000 miles (800,000 km)/10,000 hours/4 years.

Nitrite-Free Extended Life Coolant Nitrite-free organic acid technology coolant (OAT) may be used if it meets DAF 74002.

The change interval for nitrite free coolant is 600,000 miles (1,000,000 km) or 6 years, with no extender needed. DO NOT add coolant extender to nitrite-free coolant. Follow the coolant supplier's drain/flush/fill/

diluting percentages when servicing a vehicle filled with nitrite-free coolant.

Additional Recommendations:

Antifreeze is essential for freeze, overheat, and corrosion protection. The use of supplemental coolant additives (SCAs) is not recommended for extended-life coolants.

Fuel Recommendations

Precautions and recomendations for selecting and using the right diesel fuel.

WARNING

The use of diesel fuel that has been mixed with other fuels may cause an explosion. DO NOT mix gasoline, alco- hol, or gasohol with diesel fuel. Make sure you know your fuel source and use the recommended diesel fuel as indicated in this section of the manual. Failure to comply may result in death, personal injury, equipment or property damage.

CAUTION

Dirt or water in the fuel system can cause severe damage to both the fuel pump and the fuel injectors. Due to the precise tolerances of diesel injection systems, it is extremely important that the fuel be kept clean and free of dirt or water. Know your fuel source and

make sure all steps are taken for dis- pensing or using clean fuel in your ve- hicle. Failure to comply may result in equipment or property damage.

CAUTION

Unapproved fuel can reduce economy or possibly damage fuel system com- ponents. Unapproved fuels typically do not have enough lubricity elements in the fuel to properly lubricate the fuel injection system. Be sure you follow the fuel recommendations as indicated in this section of the manual. Failure to comply may result in equipment or property damage.

CAUTION

Using diesel fuels blended with lubri- cants may cause damage to your ex- haust aftertreatment system. Service intervals for aftertreatment systems will be reduced. DO NOT use diesel fuel blended with lubricating oil in en- gines equipped with an aftertreatment

system. Failure to comply may result in equipment or property damage.

CAUTION

DO NOT use high-sulfur diesel fuel as it will damage the exhaust aftertreat- ment system. Also, the engine will not meet emission regulations. Use only ultra-low-sulfur diesel (ULSD) fuel. Failure to comply may result in equip- ment or property damage.

ENGINE MAINTENANCE - Fuel Recommendations

52 Y53-1185-1E1 (04/16/18)

2

CAUTION

If ultra-low-sulfur diesel (ULSD) fuel is not used, the engine may not meet emission regulations, and damage may occur to the exhaust aftertreat- ment system. The use of high-sulfur diesel fuel will damage the exhaust af- tertreatment system and impact the engine emission. ULSD fuel is re- quired for correct operation of the af- tertreatment. The engine has been op- timized for use with an aftertreatment system together with ULSD fuel to meet the 2013 U.S. Environmental Protection Agency regulations. Failure to comply may result in equipment or property damage.

NOTE

PACCAR recommends that the cetane number of diesel fuel be a minimum of 45 for engines that are expected to op- erate at temperatures below 32F (0C) and a minimum of 42 for engines

that are operated at temperatures above 32F (0C).

Using diesel fuel with a lower-than- recommended cetane number can cause hard starting instability, and excessive white smoke. To maintain satisfactory operation at low ambient temperatures, it is important to specify diesel fuel of the correct cetane number.

PACCAR requires all permissible fuels to have adequate fuel lubricity. Lubricity can be determined by ASTM, specification D6079, ISO 12156, High Frequency Reciprocating Rig (HFRR) in which the fuel must have a wear scar diameter of 0.02 in. (0.5 mm) or less.

The use of Ultra-low-sulfer diesel (ULSD) fuel is required for this engine in order to meet emission regulations and to prevent damage to the engine and exhaust system. The use of other grades of diesel fuels other than ULSD fuel will be considered a use of incorrect fuel for the engine. PACCAR is not responsible for failures caused by the use of incorrect fuel, oil or DEF or by water, dirt or other containments in the fuel or DEF.

Warranty and the Use of Biodiesel Fuel

Biodiesel information and warranty precautions.

PACCAR Inc. approves the use of biodiesel fuel blends up to 20 percent by volume in diesel fuel providing that the following conditions are met:

The biodiesel used in the blend meets ASTM Standard D6751 or EN 14214 specifications.

The biodiesel used in the blend is sourced from a BQ-9000 Accredited Producer.

The finished blend meets the fuel properties of the ASTM Standard D975 (up to B5 blend) or D7467 (B6 to B20 blend).

If using B6-B20 the engine oil and oil filter are changed per the modified schedule. See the Engine Preventative Maintenance Schedule.

If using B6-B20 the fuel filter is changed every 25,000 miles (40,000 km).

ENGINE MAINTENANCE - Warranty and the Use of Biodiesel Fuel

Y53-1185-1E1 (04/16/18) 53

2

The use of approved biodiesel fuel does not affect the PACCAR engine warranty. Failures caused by the use of non- approved biodiesel fuels or other fuel additives that are of unacceptable quality or do not meet specified industry standards are not considered as defects of parts or workmanship by PACCAR and therefore will not be covered by the PACCAR engine warranty.

PACCAR recommends that customers intending to use biodiesel blends become familiar with the additional handling considerations of these fuels such as ageing, metal compatibility and tendency to absorb water. Please reference the fuel suppliers technical information or industry guidelines such as the American Trucking Association Truck Maintenance Council document RP 357.

In particular, operators should be aware that biodiesel blends are more prone to cold flow (gelling) and filter plugging issues compared to conventional diesel fuel. If vehicles are expected to be operated in temperatures below freezing, care should be taken to ensure that both the biodiesel fuel used and the appropriate vehicle fuel system accessory heaters are utilized.

Operators should also be aware that biodiesel energy content (by volume) is lower than diesel which can reduce fuel economy by up to two percent.

Recommendations to Avoid Fuel Gelling

Information to prevent fuel gelling in cold weather.

Use appropriate fuel grade/blend for conditions

Spec your vehicle with proper cold weather equipment (12V electric pre- heater, fuel blending valve, fuel/ coolant heater, 12V fuel line heaters and fuel tank heaters)

PACCAR does not recommend the use of fuel additives, however, should a customer decide there is a need for temporary use of a winter fuel additive, PACCAR offers the following guidance:

Use an industry known, high quality product (EPA-approved)

Check the product label to ensure it is compatible with ultra-low sulfur

diesel fuel and aftertreatment systems

Only use the additive for the minimum time needed

Follow the additive manufacturer's instructions exactly

Diesel Exhaust Fluid Recommendations and Specifications

Maintenance Procedures

Engine Oil Level How to check engine oil level

To check engine oil level, park vehicle on level ground and wait 15 minutes after shutting off engine. After the engine is shut off it will take at least 15 minutes for all the engine oil to return to the sump.

NOTE

It takes approximately 15 minutes for all the oil to run into the sump when the engine is warm. If the level is checked immediately after switching off the engine, the dipstick will show a low oil level.

Make sure that the vehicle suspension is sitting flat, both lengthwise and crosswise. Check this carefully on a vehicle with air suspension.

Engine coolant should be at or above the operating temperature of 180F (82C).

This procedure should be followed as part of routine maintenance checks.

1. Twist the dipstick handle to unlock it, then pull the dipstick out of the holder.

2. Wipe the dipstick clean with a lint- free cloth.

3. Reinsert the dipstick into the holder. 4. Remove the dipstick from the holder

and check the oil level. The oil level should always be between the two marks on the dipstick.

5. Reinstall the dipstick and twist to lock it in place.

Oil Filter Removal Preparation This procedure should be followed before replacing engine oil filters.

CAUTION

Before beginning to remove and/or disconnect any components, wait at least 5 minutes after the key switch is turned OFF for the aftertreatment DEF dosing system to purge the DEF from the system. The DEF system purges to prevent damage from freezing. Fail- ure to comply may result in equipment or property damage.

WARNING

Turn off the engine and place the igni- tion switch in the OFF position before disconnecting the battery clamps. DO NOT place any tools or other materials on top of or close to the batteries. This can cause a dangerous high current short circuit and, in the worst case, a battery explosion. Keep all objects away from the battery terminals. Al- ways break the contact between the

battery clamp and the negative termi- nal before working on the vehicle. Working on a vehicle while the battery is connected may result in electrical in- jury or damage. Always disconnect the battery at the negative terminal when performing service procedures. Failure to comply may result in death, person- al injury or equipment damage.

WARNING

Electrical shock hazard: Never discon- nect the battery clamp when the en- gine is running. Disconnecting the bat- tery clamps while the engine is running may result in death, personal injury or equipment damage from electrical arc- ing or damage to electrical compo- nents.

1. Disconnect the chassis battery cable at the negative battery terminal.

2. Place an oil collection pan directly under the oil filter.

After Replacing Engine Oil Filter(s) Procedure for what to do after installing new oil filters.

Follow the steps below after installing new oil filters:

1. Reconnect the chassis battery cable at the negative battery terminal. See "Oil Filter Removal Preparation."

2. Add SAE-approved CK-4/CJ-4 engine oil to the maximum level marked on the dipstick. If the engine is running a different weight of oil, be sure to top-off the engine oil with the same brand and viscosity of oil.

3. Start and run the engine for 5 to 10 minutes and check for any oil leaks.

4. Remove oil collection pan and dispose of any spillage properly.

Fuel Filter Important information on replacing engine mounted cartridge type fuel filters.

Perform these maintenance procedures according to the Preventative Maintenance Schedule.

WARNING

When removing the fuel filter, a quanti- ty of fuel will escape. DO NOT smoke or allow an open flame in close prox- imity. Failure to do so could ignite a fire or cause an explosion which could result in serious injury to you and/or bystanders. Failure to comply may re- sult in death, personal injury, equip- ment or property damage.

NOTE

The fuel filter and the hand pump are located on the left-hand side of the en- gine, as viewed from the driver's seat.

NOTE

Use of poor quality fuel may require more frequent fuel filter element serv- ice.

Description The fuel filter/water separator module provides fine-particle filtration, water separation, water-in fuel-sensing, automatic water draining, lifetime purification of drained water with a charcoal filter, 12V preheating and system manual priming in a singular easy to service module.

Replace the suction side and the pressure side fuel filters at the same time. It is recommended to replace the fuel filters at the same interval as the oil and oil filter are changed. If the oil drain interval being used is greater than 15,000 mi (24,000 km), as determined by the Engine Lubrication and Filter Intervals, the fuel filter change can be extended until the oil drain interval.

NOTE

The engine and fuel module should be operated in cold climates with accepta- ble cold climate fuel blends which no- ticeably reduces wax gelling in the fuel filter cartridge. The fuel module in- cludes a 12V preheater to support pre- heat of the fuel for initial start-up in mild climates. Failure to operate with acceptable cold climate fuel may result in insufficient fuel flow to the fuel injec- tion system.

Biodiesel For information on alternative fuels, such as biodiesel, and additional information for fuel recommendations and specifications refer to "Fuels for Cummins Engines," Bulletin 3379001.

3. Tighten the fuel filter cap by rotating it clockwise until the filter cap O-ring makes contact with the fuel module. Then tighten the filter cap to 30 lb-ft (40 Nm) as specified on the filter cap.

4. If installing a new fuel filter on a PX-7, loosen the fuel priming pump knob by rotating it counter-clockwise.

NOTE

The PX-9 uses an electric pri- ming pump. If installing a new fuel filter on a PX-9 engine first vent the fuel system at the quick- disconnect fitting at the pressure side filter head inlet. The vent overflow may be routed back to the fuel tank, or, into a vented container. Cycle the ignition switch to the ON position every 2 minutes (to power the electric lift pump) until fuel appears in the chassis-mounted fuel filter hous- ing and a solid stream of fuel flows out of the vent., then skip to Step 6.

5. Operate the priming pump by moving the knob in and out for 150 seconds.

During this time the pumping resistance will increase but the full time is required to fully prime the fuel system. Then tighten the knob by rotating it clockwise.

CAUTION

Operate priming pump at a maxi- mum rate of 30 strokes per mi- nute to prevent damage to pump.

6. Check for leakage at the fuel filter cap. Tighten if necessary.

WARNING

Check the fuel filter for signs of leakage. DO NOT smoke or al- low an open flame in close prox- imity. Failure to do so could ignite a fire or cause an explosion which could result in serious in- jury to you and/or bystanders. Failure to comply may result in death, personal injury, equipment or property damage.

7. Start the engine and allow it to idle for several minutes. Note that it could take up to 15 seconds of cranking for

the engine to start. If the starter is engaged for longer than 20 seconds without starting, additional priming pump actuation may be necessary.

CAUTION

If the engine is cranked exces- sively Starter Protection will be triggered and starter engage- ment will be restricted for 10 mi- nutes.

8. Check the system for leakage while idling. Then turn the engine off and check the system again for leakage.

Starting After the Fuel Tank Has Run Dry or After Fuel System Service has been Performed Procedure for starting the engine after running out of fuel.

1. Loosen the fuel primer pump knob by rotating it counter-clockwise.

2. If equipped with a return fuel blending valve, turn the valve to the PRIME (closed) position.

3. Operate the priming pump by moving the knob in and out for 150 seconds. During this time the pumping resistance will increase, but the full time is required to fully prime the fuel system.

CAUTION

Operate priming pump at a maxi- mum rate of 30 strokes per mi- nute to prevent damage to pump.

4. Check for leakage at the fuel filtercap. Tighten if necessary.

WARNING

Check the fuel filter for signs of leakage. DO NOT smoke or al- low an open flame in close prox- imity. Failure to do so could ignite a fire or cause an explosion which could result in serious in- jury to you and/or bystanders. Failure to comply may result in death, personal injury, equipment or property damage.

5. Start the engine and allow it to idle for several minutes. Note that it could take up to 15 seconds of cranking for the engine to start. If the starter is engaged for longer than 20 seconds without starting, additional priming pump actuation may be necessary.

CAUTION

If the engine is cranked exces- sively Starter Protection will be triggered and starter engage- ment will be restricted for 10 mi- nutes.

NOTE

Allowing the engine to idle for several minutes with the fuel blending valve in the prime posti- tion assists in purging air from the fuel system.

6. Check the system for leakage while idling. Then turn the engine off and check the system again for leakage.

7. If the engine does not start within this time, repeat steps two and three until the engine starts. If the engine still does not start, allow the starter to cool down for at least 5 minutes before repeating the procedure.

Valve Position 1. Run (open) 2. Prime (closed)

8. If equipped with a return fuel blending valve, turn the bypass to the RUN (open) position.

NOTE

Failure to return the bypass to the RUN (open) position will pre- vent fuel recirculation and heat- ing.

WARNING

DO NOT loosen any fuel line fit- tings in order to bleed the fuel system of air. The system is un- der high pressure which, when relieved, could cause death, per- sonal injury, equipment or prop- erty damage.

Cooling System Important information on replacing coolant filters.

Your engine may be equipped with a coolant filter designed to capture and remove harmful deposits from the cooling system to help prolong system life. Refer to the Preventative Maintenance Schedule for the recommended coolant filter change service interval.

WARNING

Do not remove the surge tank fill cap on a hot engine. It can cause scalding coolant to spray out and you could be burned. If the engine has been operat- ed within the last 30 minutes, be very careful in removing the radiator cap. Protect face, hands, and arms against escaping fluid and steam by covering the cap with a large, thick rag. Failure to comply may result in death, person- al injury, equipment or property dam- age

WARNING

Handle coolant and antifreeze careful- ly. Ethylene glycol antifreeze is poison- ous. Store in original fluid container only, and always keep out of the reach of children. Never remove the filler cap (vertically mounted) on the surge tank while the engine is still hot. Wait until the coolant temperature is below 120F (50C). Scalding steam and flu- id under pressure may escape and cause serious personal injuries. The pressure cap (horizontally mounted) on the surge tank should never be opened. Failure to comply may result in death, personal injury, equipment or property damage.

Coolant/Antifreeze Condition Maintenance checks for ensuring proper coolant\anti-freeze condition.

Perform these maintenance procedures according to the Preventative Maintenance Schedule.

ENGINE MAINTENANCE - Maintenance Procedures

Y53-1185-1E1 (04/16/18) 63

2

NOTE

Test the engine coolant at least twice per year to determine if the coolant must be replaced. If it is determined that the coolant should be replaced, make sure to flush the coolant system. Contact a PACCAR Authorized Re- pair Location for flushing the coolant system.

Service interval is every oil change or 15,000 mi (24,000 km), 500 hours, or 6 months, whichever occurs first. A heavy- duty, year-round antifreeze that meets the chemical composition of GM6038M must be used. The change interval is 2 years or 240,000 mi (385,000 km), whichever occurs first. Antifreeze is essential for freeze and corrosion protection. Supplemental coolant additives are essential for liner pitting and scaling protection.

1. Check the following anti-freeze conditions:

Coolant level Freeze point pH level

Nitrite level Carboxylate level

Checking Coolant Condition Recommended coolant checks.

To ensure the Extended Life Coolant (ELC) in your vehicle always provides maximum protection, perform the following tests:

1. Check the coolant color at every maintenance interval. It should have no cloudiness, floating debris, or oils.

2. Test the freeze point at least twice a year. A refractometer or test strips can be used to measure the protection level.

3. Determine the pH and chemical inhibitor concentration level by using an ELC-specific test kit or test strips.

4. Keep the cooling system full by topping-up using ELC pre-diluted to a 50/50 blend, unless a different ratio of water/antifreeze has been substituted (depending on operating conditions).

NOTE

Inhibitor concentration level de- termines corrosion protection. If you are concerned about possi- ble coolant quality, contamina- tion, or mechanical problems, submit a coolant sample to your dealer for analysis. Improper maintenance may cause coolant degradation and could result in damage to the cooling system and engine components. Consult your dealer or the coolant manu- facturer's representative for rec- ommended extended life coolant test kits, test strips, and laborato- ry sample procedures.
