2 WHAT TO DO IF... 2-6 • 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. • 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 fire. Failure to comply may result in death, personal injury, equipment or property damage. 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. • Scalding steam and fluid under pressure may escape and cause serious personal injuries. • Wait until the coolant temperature is below 122°F (50°C). • Protect your face, hands, and arms by covering the cap with a large, thick rag to protect against escaping fluid and steam. • 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.
CAUTION: Do not allow your engine to idle, at low RPMs (400–600 rpm), longer than 5 minutes. 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 flashing warning lamp will inform the driver of an impending shutdown. 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. WHAT TO DO IF... 2-7 2
