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.

2

(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.

2

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.

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.

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.

3

(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

3

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.
