Engine Overheating
The vehicle has a coolant temperature gage displayed
on the instrument panel to warn if the engine is
overheating. See Engine Coolant Temperature
Gage on page 3-29. If the engine is too hot, the air
conditioning might stop working. This is normal
and helps cool the engine.
You may decide not to lift the hood when the warning
appears, but instead get service help right away.
See Roadside Assistance Program on page 7-7.
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 engine cooling fan speed should increase when
idle speed is doubled by pushing the accelerator pedal
down. If it does not, the vehicle needs service.
Turn off the engine.
Notice: Engine damage from running the engine
without coolant is not covered by the warranty.
Notice: If the engine catches ?re 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 ?re. You or others could
be badly burned. Stop your engine if it overheats,
and get out of the vehicle until the engine is cool.
