Y53-1181-1B1 (07/19/2013)

WHAT TO DO IF...

Check Engine Lamp Turns On

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.

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 damage.

NOTE

The system may also temporarily overheat during severe operating conditions such as:

• Climbing a hill on a hot day.

• Stopping after high-speed/highload driving.

• Debris blocking air ow 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:

• Reduce engine speed or stop.

When stopped, place the transmission in neutral and set the parking brake. See the vehicle operator's manual for instructions on transmission shifting and parking brake information.

• Check to ensure that the oil

pressure gauge reads normal.

• Increase the engine speed to

1,100 to 1,200 rpm maximum for 2-3 minutes.

(07/19/2013) Y53-1181-1B1 2-5

WHAT TO DO IF...

• Monitor the engine temperature.

After the temperature returns to normal, allow the engine to idle 3–5 minutes before shutting it off.

This allows the engine to cool gradually and uniformly.

• If the overheating came from

severe operating conditions, the temperature should have cooled by this time.

• Check the coolant level at the

cooling module surge tank.

WARNING!

To reduce the chance of personal injury and/or vehicle damage caused by engine overheating, never leave the engine idling when the vehicle is unattended. If the engine overheats, immediate action is required to correct the condition. Continued unattended operation of the engine, even for a short time, may result in serious engine damage or a re. Failure to comply may result in death, personal injury, equipment or property damage.

WARNING!

Removing the ll 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 previous 30 minutes, be very careful in removing the ll cap. Protect face, hands, and arms against escaping uid 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 escaping. In any situation, remove the cap very slowly and carefully. Be ready to back off if any steam or coolant begins to escape. See the vehicle operator's manual for instructions on checking and lling the cooling module surge tank.

2-6 Y53-1181-1B1 (07/19/2013)

WHAT TO DO IF...

CAUTION

Prolonged periods of idling after the engine has reached operating temperatures can decrease engine temperature and could cause engine damage from inadequate lubrication. The normal torsional vibrations generated can also cause transmission wear. An idle shutdown feature, available on PACCAR engines, can be programmed to shut the engine down after a period of low idle operation with no driver activity. A ashing warning lamp will inform the driver of an impending shutdown. Failure to comply may result in equipment or property damage.

CAUTION

If the truck is equipped with PTO equipment, the engine shutdown system can be deactivated when the PTO is operational; however, engine idle periods should not exceed 5 minutes whenever possible. Failure to comply may result in equipment or property damage.

Engine Warning Lamps

General Information

The following engine warning lamps cover only the lamps controlled by the engine’s Electronic Control Module (ECM). Please refer to the vehicle Operator's and Engine Aftertreatement Systems manual for additional warning lamp information.

Check Engine Lamp

The check engine warning lamp will illuminate when a problem exists, but the vehicle can still be safely driven. The 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 is required. 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 engine ECM begins ashing 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.

(07/19/2013) Y53-1181-1B1 3-3

Operating Instructions

Stop Engine Lamp

The stop engine warning lamp will

illuminate, and an audible tone will sound, when a major engine problem exists.

WARNING!

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 corrected before driving again. Failure to comply may result in personal injury, severe engine damage, equipment or property damage.

For engines with the engine protection shutdown feature enabled, the stop engine lamp will begin to

ash 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 Diesel Exhaust Fluid (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 light and Stop Engine light are illuminated and the operator does not correct the condition.

NOTE

The Malfunction Indicator Lamp (MIL) will illuminate if the OBD (Onboard Diagnostics) system detects a possible emissions system failure. The vehicle should be brought in for service at the next opportunity to ensure the condition is corrected.

Engine Operating Range

General Information

CAUTION

Operating the engine at full throttle below 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 torque rpm for more than 30 seconds. Failure to comply may result in equipment 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 maximum engine speed can cause severe engine damage. Use proper operating techniques for the vehicle to prevent engine overspeed. The maximum engine speed specication is listed in the “General Engine Specications” on page 5-12. Failure to comply may result in equipment or property damage.

NOTE

For applications with high idle time, to help reduce soot loading in the aftertreatment system, avoid long periods of idling. If idling is required increase idle speed using the cruise control function.

3-6 Y53-1181-1B1 (07/19/2013)

Operating Instructions

Engine Braking System

WARNING!

Do not operate the engine compression brake when driving/operating your vehicle bobtail or with a loaded or unloaded trailer on road surfaces with poor traction (wet, icy, or snow covered roads) or in heavy trafc. Braking caused by the normal operation of the engine compression brake could cause you to lose control of the vehicle resulting in an injury accident. Failure to comply may result in death, personal injury, equipment 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 engine backpressure to slow the drivetrain. Use the service brakes for quick stops. You could be seriously injured if you relied only on the engine compression brake to stop the vehicle in an emergency. Failure to comply may result in death, personal injury, equipment or property damage.

WARNING!

Do not use the compression brake when operating on road surfaces with poor traction (such as wet, icy, or snow covered roads or gravel). Compression brakes 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.

NOTE

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

(07/19/2013) Y53-1181-1B1 3-7

Operating Instructions

An engine compression brake is standard on the PACCAR MX-13 engine. When activated, the engine compression brake creates a braking effect on the drive wheels. This device uses engine power to slow the vehicle down. Because it can help keep your vehicle’s brakes from

overheating, it can save wear and tear on the service brakes. However, the engine compression brake is not an emergency brake.

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

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).

• Do not use the engine

compression brake to slow the vehicle down when you are bobtailing or pulling an empty trailer.

• Make sure the brake is OFF before

starting the engine.

• 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, operation of the compression brake may be automatically activated.

3-8 Y53-1181-1B1 (07/19/2013)

Operating Instructions

Compression Brake Controls

Two (2) switches on the dash panel 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.

• 3-position selector switch.

• Clutch switch.

• Throttle sensor.

• Service brake pressure switch.

• Eaton Vorad® Anti-Lock Braking

System.

Engaging conditions for the engine compression brake are:

• Engine speed must be above

1,000 rpm.

• Coolant temperature must be

above 59°F (15°C).

Deactivation conditions for the engine compression brake are:

• Accelerator pedal is depressed.

• Clutch pedal is depressed.

• Engine speed falls below 800 rpm.

• ABS control is active.

• Engine ECM recognizes a system

problem.

CAUTION

Operating the engine with a compression 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 internal engine damage. Do not operate the engine if the compression brake will not deactivate. Failure to comply may result in equipment or property damage.

(07/19/2013) Y53-1181-1B1 3-9

Operating Instructions

Engine Compression Brake Level Switch Operation

There are 2 switches that control your vehicle’s 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 3-position engine compression brake level switch, there will be 100% engine braking when the switch is in the up (HIGH) position. In the middle (MEDIUM) position, there will be 66% engine braking. In the down (LOW) position there will be 33% 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.

Correct care of your engine will result in longer life, better performance, and more economical operation.

Follow the daily maintenance checks listed in “Maintenance Schedule” on page 5-4.

Check the engine oil pressure and engine coolant gauges, warning lights, and other gauges daily to make sure they are operational.

WARNING!

Combustible vapors near the air intake system could be ingested into the engine, causing the engine to suddenly accelerate and overspeed. This condition could result in operator losing control of the vehicle if an unexpected increase in engine rpm occurs. Combustible vapors could also cause a re. 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.

IT IS THE RESPONSIBILITY OF THE OWNER AND OPERATOR TO OPERATE THE VEHICLE IN A SAFE ENVIRONMENT.

(07/19/2013) Y53-1181-1B1 4-3

Operating Instructions

Normal Starting Procedure

Starting

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

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

3. Release the key after 10 seconds

if the engine does not start. Then wait 10 seconds and try again.

NOTE

If the engine is running, do not increase 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 5 minute period may cause it to overheat and can damage the starter motor.

• If starter is engaged continuously for 30 seconds, you must wait 5 minutes before trying to start the engine to allow the starter motor to cool down.

If the engine does not start, or runs erratic, follow the procedure under “Starting After the Fuel Tank Has Run Dry”, see on page 5-30.

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

1. Check engine lamp; yellow in color.

2. STOP engine lamp; red in color.

3. Diesel Particulate Filter (DPF) status indicator; yellow in color.

4. High Exhaust System Temperature (HEST); amber in color.

Operating Instructions

Cold Weather Starting

General Information

Follow the “Normal Starting Procedure” on page 4-4.

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

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.

The use of cold starting aids are not recommended for ambient temperatures above 0° F (-18° C).

If an engine must idle for an extended period of time, it should be done at a fast idle (1000 rpm maximum) at coolant temperatures below 150° F (70° C).

For coolant temperatures below 150° F (70° C), 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.

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 lubricating oil

• Carbon buildup in the cylinder

• Sticking of the valves in the cylinder head

• Reduced performance

• Damage to aftertreatment components

Operating Instructions

Operating the Engine

Normal

Monitor the oil pressure and coolant temperature gauges frequently. Refer to “Lubricating Oil System” and “Cooling System” for recommended operating pressures and temperatures. Shut off the engine if any pressure or temperature does not meet the specications.

Engine Shutdown

Before Stopping the Engine

NOTE

Do not shut off the engine immediately. 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 4 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.

Electromagnetic Interference (EMI)

General Information

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 electronic 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 specications. 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 reective energy data measurements.

° Ensure that the optimum

antenna type and mounting arrangement is being used.

° Ensure the accessory

equipment is properly constructed for maximum ltering to reject incoming electromagnetic noise.

Overview

General Information

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

If the engine is operating in ambient temperatures below 0°F (-18°C) or above 100°F (38°C), 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 qualied 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.

Oil Drain Intervals

Oil drain interval recommendations are based on vehicle application or engine duty cycle. PACCAR recommends the use of high quality lubricating oil as indicated in the Lubricating Oil Recommendations in the Maintenance Specications Section.

Lubricating Oil Recommendations and

Specications

General Information

CAUTION

Extending the oil and lter change interval beyond the recommendations will decrease the engine life due to factors such as corrosion, deposits, and wear. Engine oil lters capture dirt and remove deposits from the oil to prolong the life of internal moving components. Follow the oil and lter change intervals as recommended in this section of the manual. Failure to comply may result in equipment or property damage.

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 lter change intervals. Attempting to extend the oil

and lter change interval beyond the manufacturers recommendations may decrease engine life.

NOTE

It is the operator’s responsibility to abide by these recommendations to ensure that the engine warranty does not get affected.

PACCAR recommends the use of high-quality SAE 10W30 API CJ-4 heavy-duty engine oil.

The primary PACCAR recommendation is for the use of 10W30 multigrade lubricating oil for normal operation at ambient temperatures above 5°F (-15°C). For ambient temperatures below 5°F (-15°C) SAE 5W30 may be used, provided it meets API CJ-4 oil specications and biodiesel or biodiesel blended fuel is not used as fuel for the engine. Using a multigrade

oil helps improve engine cranking in low-temperature conditions, reduces deposit formation and increases engine durability.

New Engine Break-In Oils

PACCAR does not approve the use of special “break-in” engine lubricating oils for new or rebuilt PACCAR engines. It is recommended to use the same lubricating oil for engine break-in that will be used during normal operation.

(07/19/2013) Y53-1181-1B1 5-17

Maintenance Specications

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 sufcient 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.

Coolant Recommendations and Specications

The cooling system in your vehicle was factory lled with Extended Life Coolant (ELC) that meets or exceeds all ASTM D 6210 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 -34°F (- 36.7°C), 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

-62°F (-52.2°C).

Your engine is also equipped with a Coolant Filter designed to capture and remove harmful deposits from the cooling system to help prolong system life.

CAUTION

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

Maintenance Specications

Checking Coolant Condition Recommended Extended Life Cooling System Sealing Additives

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

1. Check the coolant color at every maintenance interval. It should be a bright red with no signs of debris or any oil.

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

PACCAR warrants to the rst purchaser or rst lessee and each subsequent purchaser that the Engine is designed, built and equipped so as to conform at the time of sale by PACCAR with all U.S. Federal emission regulations applicable at the time of manufacture and that it is free from defects in material or factory workmanship which would cause it not to meet these regulations within the longer of the following periods: (A) Five years or 100,000 miles (160,000 kilometers) of operation, whichever occurs rst, as measured from the date of delivery of the Engine to the rst purchaser or rst lessee or (B) The Base Engine Warranty.

If the vehicle in which the Engine is installed is registered in the state of California, a separate California Emission Warranty also applies.

Replacement Parts

PACCAR recommends that any service parts used for maintenance, repair or replacement of emission control systems be new or genuine approved rebuilt parts and assemblies, and that the engine be serviced by an authorized PACCAR Engine dealer. Your vehicle contains air, fuel, and electrical components that may affect engine emission controls. The use of non-genuine engine or vehicle replacement parts that are not equivalent to the PACCAR engine or OEM vehicle manufacturer’s original part may impair the engine and vehicle emissions control system from working or functioning effectively, and may jeopardize your emissions warranty coverage.

Warranty

Limitations

Your sole and exclusive remedy against PACCAR and the Selling Dealer arising from your purchase and use of this Engine is limited to the repair or replacement of “warrantable failures” at authorized United States and Canadian PACCAR Engine Dealers, or an authorized PACCAR Engine facility where applicable, subject to PACCAR’s time, mileage, and hour limitations of the engine emission warranty. The maximum time, mileage and hour limitations of the engine emission warranty begin running on the Date of Delivery to the rst purchaser or rst lessee. The accrued time, mileage, or hours is calculated when the engine is brought into an Authorized Dealer for correction

of warrantable failures.

Failures, other than those resulting from defects in material or factory workmanship, are not covered by this

Warranty. PACCAR is not responsible for failures or damage resulting from what PACCAR determines to be abuse or neglect, including, but not limited to: damage due to accident; operation without adequate coolants or lubricants; overfueling; overspeeding; lack of maintenance of lubricating, cooling or intake systems; improper storage, starting, warm-up, run-in or shutdown practices; unauthorized modications of the Engine. PACCAR is also not responsible for failures caused by incorrect oil, fuel or diesel exhaust uid or by water, dirt or other contaminants in the fuel, oil or diesel exhaust uid. Failure of replacement parts used in repairs due to the above non-warrantable conditions is not warrantable.

PACCAR is not responsible for non-Engine repairs, downtime expenses, cargo damage, nes, all applicable taxes, all business costs

or other losses resulting from a Warrantable Failure.

THIS LIMITED EMISSION WARRANTY IS THE SOLE WARRANTY MADE BY PACCAR RELATING TO THE EMISSION EQUIPMENT. EXCEPT FOR THE ABOVE LIMITED WARRANTY, PACCAR MAKES NO OTHER WARRANTIES, EXPRESS OR IMPLIED. PACCAR EXPRESSLY DISCLAIMS ANY WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.
