WHAT TO DO IF...

4.Return the engine speed to normal idle after two or three minutes.

5.Monitor the engine temperature.

2	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.

6.If the overheating came from severe operating conditions, the temperature should have cooled by this time.

7.Check the sight gauge (glass level indicator) on the side of the coolant expansion tank.

WARNING!

Removing the surge tank fill cap while the engine is hot can be dangerous. Never remove the surge tank cap while the engine is still hot; you could be badly burned. Failure to comply may result in death, personal injury, equipment or property damage.

Removing the surge tank fill cap while the engine is too hot is dangerous. Scalding steam and fluid under pressure may escape and cause serious personal injuries. When removing the surge tank fill cap, follow these steps:

1.Wait until the coolant temperature is below 122°F [50°C].

2.Protect your face, hands, and arms by covering the cap with a large, thick rag to protect against escaping fluid and steam.

3.Carefully and slowly turn the cap one turn to allow excess pressure to escape, then push down and turn for final removal. See the vehicle operator's manual for instructions on checking and filling 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. Iftheengineoverheats, immediate action is required to correct the condition. Continued unattendedoperationoftheengine,even for a short time, may result in serious engine damage or a fire. Failure to comply may result in death, personal injury, equipment or property damage.

2-6

WHAT TO DO IF...

CAUTION

Do not allow your engine to idle, at low rpm's (400-600 rpm), longer than five minutes. Long periods of idling after the engine has reached operating temperatures can decrease engine temperature and cause gummed piston rings, clogged injectors, and possible engine damage from lack of lubrication. The normal torsional vibrations generated by the engine can also cause transmission wear. If an engine must idle for an extended period of time, it should be done at fast idle (1,000 rpm or greater).

NOTE
An idle shutdown feature, available
on PACCAR Engines, can be pro-
		2
grammed to shut the engine down
after a period of low idle speed op-
eration with no driver activity. A
flashing warning lamp will inform the
driver of an impending shutdown.
NOTE
The power take off (PTO) feature,
available on PACCAR engines, can
beprogrammedtoadjustengineidle
speed with the use of switches to
pre-programmed set points.

Engine Warning Lamps

Wait-to-Start Lamp

Check Engine Lamp

General Information

The following engine indicator lamps cover only the lamps controlled

by the engine's ECM. The vehicle manufacturer can provide additional indicator lamps. Please refer to the vehicle's operator's manual for additional lamp information.

The WAIT TO START lamp illuminates when the intake air heater (grid heater) needs to warm the intake air prior to starting the engine.

The WAIT TO START lamp can look like:

•The words WAIT TO START spelled out

•A symbol similar to the graphic illustrated

•The color of the symbol or words can vary, based on the manufacturer of the vehicle, but will typically be red or amber.

The CHECK ENGINE lamp illuminates when the engine needs service at the 3 first available opportunity.

The CHECK ENGINE lamp is amber, and can look like:

•The words WARNING or CHECK ENGINE spelled out.

•A symbol of an engine, similar to the graphic illustrated.

The CHECK ENGINE lamp is located on the face of the tachometer and illuminates 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

3-3

OPERATING INSTRUCTIONS

Check Engine lamp will activate for several reasons. These include but are not limited to Water in Fuel and Diesel Particulate Filter (DPF) generation required.

Another function of the CHECK ENGINE lamp is to flash for 30 seconds at key ON when one of the

3 following occurs. This flashing function is referred to as the MAINTENANCE lamp. The MAINTENANCE lamp could flash for any of the following reasons:

•Maintenance required (if the Maintenance Monitor is enabled)

•Water-in-fuel is detected

•Coolant level is low.

Malfunction Indicator Lamp

Illuminates when an engine emissions failure has occurred. The vehicle can be safely driven but should be serviced to correct the problem. The situation should not be considered an emergency. In some cases, the Malfunction Indicator Lamp will activate in conjunction with the High Exhaust Temperature, Diesel Particulate Filter (DPF) and Diesel Exhaust Fluid (DEF) Warning Lights.

Stop Engine Lamp

The STOP ENGINE lamp indicates, when illuminated, the need to stop the engine as soon as it can be safely done. The engine must remain shut down until the engine can be repaired.

For engines with the Engine Protection Shutdown feature enabled, if the STOP ENGINE lamp begins to flash, the engine will automatically shut down after 30 seconds. The flashing STOP engine lamp alerts the operator to the impending shutdown.

OPERATING INSTRUCTIONS

High Exhaust System Temperature

(HEST) Warning Lamp

HEST Warning Lamp

Refer to Engine Aftertreatment Systems Operator's Manual for additional information.

Diesel Particulate Filter (DPF)

Warning Lamp

A flashing AFTERTREATMENT DIESEL PARTICULATE FILTER lamp indicates that the aftertreatment diesel particulate filter needs to be regenerated at the next possible opportunity. Engine power may be reduced automatically. When this lamp is flashing, the operator should:

1.Change to a more challenging duty cycle, such as highway driving, for at least 20 minutes.

2.Performing a stationary regeneration.

A flashing AFTERTREATMENT DIESEL PARTICULATE FILTER lamp combined with an illuminated WARNING or CHECK ENGINE lamp indicates that the aftertreatment diesel particulate filter needs be regenerated immediately. Engine power will be

reduced automatically.

3

When these lamps are illuminated, a stationary regeneration is required.

NOTE

If a stationary regeneration is not performed, the STOP ENGINE lamp will illuminate and the vehicle will needtobetakentoanauthorizedrepair location.

Refer to Engine Aftertreatment Systems Operator's Manual for additional information.

OPERATING INSTRUCTIONS

Diesel Exhaust Fluid (DEF) Lamp

Diesel Exhaust Fluid (DEF) Lamp

3 The AFTERTREATMENT DIESEL EXHAUST FLUID lamp indicates, when illuminated or flashing, that the diesel exhaust fluid level is low.

An illuminated AFTERTREATMENT DIESEL EXHAUST FLUID lamp indicates that the diesel exhaust fluid level has fallen below the initial warning level. This can be corrected by filling the diesel exhaust fluid tank with diesel exhaust fluid.

NOTE

Itisrecommendedthatthedieselexhaust fluid tank be filled completely full of diesel exhaust fluid in order to correct any fault conditions.

A flashing AFTERTREATMENT DIESEL EXHAUST FLUID lamp indicates that the diesel exhaust fluid level has fallen below the critical warning level. This can be corrected by filling the diesel exhaust fluid tank with diesel exhaust fluid.

NOTE

Itisrecommendedthatthedieselexhaust fluid tank be filled completely full of diesel exhaust fluid in order to correct any fault conditions.

A flashing AFTERTREATMENT DIESEL EXHAUST FLUID lamp combined with an illuminated WARNING or CHECK ENGINE lamp

indicates that the diesel exhaust fluid level has fallen below the initial derate level. The engine power will be limited automatically. This can be corrected by filling the diesel exhaust fluid tank with diesel exhaust fluid.

NOTE

Itisrecommendedthatthedieselexhaust fluid tank be filled completely full of diesel exhaust fluid in order to correct any fault conditions.

Allowing the diesel exhaust fluid tank to become empty will cause the aftertreatment diesel exhaust fluid dosing system to lose prime. A loss of prime condition may cause fault codes to become active.

NOTE

On OBD certified products, the MIL may become illuminated for a loss of prime condition.
