Isuzu N Series - When the Engine Overheats

8-27
IN CASE OF EMERGENCY
If engine power drops and the needle on the engine coolant temperature gauge goes
up above the upper limit of the safety zone and enters the "H" zone, the engine is
overheating. The engine overheat warning light will come on (if equipped) and the
warning buzzer will sound. Either steam or boiling water will squirt out of the radiator.
Take the following corrective actions immediately.
1. Operate the hazard warning flasher
and pull the vehicle immediately over
to a safe place that does not impede
traffic (shoulder, verge) and park it.
2. Lower the temperature of the engine
for a while with the engine idling.
ADVICE
Do not stop the engine immediately.
Otherwise, the engine may seize.
•
3. When the needle of the engine
coolant temperature gauge returns to
the middle of the safety zone, stop the
engine.
WARNING
Even when the engine has been stopped, the engine coolant in the radiator
remains under pressure. Immediately removing the radiator cap could cause
steam or hot water to blow out, and you could be scalded as a result. The
engine coolant in the reserve tank may also be hot. Immediately removing the
cap could cause hot water to blow out, and possibly scald you.
When removing the radiator cap and reserve tank cap, use a thick cloth to cover
the cap and turn it little by little.
