WHAT TO DO IF...
2
•
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!
WARNING!
To reduce the chance of personal in-
jury 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 cor-
rect the condition. Continued unat-
tended operation of the engine, even
for a short time, may result in seri-
ous engine damage or a fire. Failure
to comply may result in death, per-
sonal injury, equipment or property
damage.
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.
