Engine Overheating
The vehicle has an indicator to warn
of engine overheating.
A coolant temperature gage is
displayed on the instrument panel.
See Engine Coolant Temperature
Gage on page 3-29.
You may decide not to lift the hood
when this warning appears, but
instead get service help right away.
See Roadside Service on page 7-6.
If you do decide to lift the hood,
make sure the vehicle is parked on
a level surface.
Then check to see if the engine
cooling fans are running. If the
engine is overheating, both fans
should be running. If they are not, do
not continue to run the engine and
have the vehicle serviced.
The air conditioning might stop
working if the engine is too hot.
This is normal and helps cool the
engine.
Notice: Engine damage from
running the engine without
coolant is not covered by the
warranty.
Notice: If the engine catches fire
because of being driven with
no coolant, your vehicle can be
badly damaged. The costly
repairs would not be covered by
the vehicle warranty.
If Steam Is Coming From The
Engine Compartment
{ CAUTION
Steam from an overheated engine
can burn you badly, even if you
just open the hood. Stay away
from the engine if you see or hear
steam coming from it. Just turn it
off and get everyone away from
the vehicle until it cools down.
Wait until there is no sign of
steam or coolant before you
open the hood.
If you keep driving when your
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop your
engine if it overheats, and get
out of the vehicle until the engine
is cool.
