WHAT TO DO IF...
transmission in neutral (N) 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
two to three minutes.
•
Monitor the engine temperature.
After the temperature returns
to normal, allow the engine to
idle three to five 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.
•
Be sure the vehicle is parked on
level ground or the readings may
be incorrect. Check the coolant
level at the cooling module surge
tank.
WARNING!
To reduce the chance of per-
sonal injury and/or vehicle damage
caused by engine overheating,
never leave the engine idling when
the vehicle is unattended. If the en-
gine 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 com-
ply may result in death, personal
injury, equipment or property dam-
age.
WARNING!
Removing the fill cap on a hot en-
gine can cause scalding coolant
to spray out and burn you badly.
If the engine has been in opera-
tion within the previous 30 minutes,
be very careful in removing the fill
cap. Protect face, hands, and arms
against escaping fluid 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 filling
the cooling module surge tank.
