If The Engine Overheats - Mitsubishi FUSO FE 2006 Owner's Manual

WARNING
Open the pressure cap only after the coolant
temperature has dropped sufficiently. If the
cap is opened while the engine is still hot,
boiling coolant could gush out, burning you
Z12079
severely.
CAUTION
•
Be sure to stop the engine only after letting it
run at a speed slightly above the idling RPM
until the coolant cools down. Turning off the
engine immediately after stopping will cause
the coolant temperature to rise quickly and
may cause the engine to seize up.
•
Suddenly pouring cold water into the radia-
tor could make the engine crack. Supply
cold water a little at a time.
If the needle in the coolant temperature gauge
enters the red zone
Stop the vehicle in a safe place, and allow the
engine to cool by using the engine idling control vol-
ume or accelerator pedal to run the engine at a
speed slightly higher than the idling speed.
When the needle in the coolant temperature gauge
has come down to approximately the middle of the
scale, stop the engine and perform the following
inspections and corrective steps:
Z09375
1. Check that coolant is not leaking from the radia-
tor hoses or from other parts.
2. Check that the fan belt is not broken and that its
tension is normal.
3. Check the coolant level. If the level is too low,
add coolant.
•
Remove the pressure cap, then add coolant
until it reaches the top of the pressure cap
opening.
•
Remove the reservoir tank cap, then add
coolant until it reaches the "FULL" line.
4. Check that there is no dirt stuck to the front of
the radiator.
5. If coolant leaks or the engine repeatedly over-
heats, the cooling system is faulty. Have an
authorized dealer perform necessary inspection.
