Engine Overheating

The vehicle has an engine coolant
temperature gauge on the instrument
cluster to warn of engine overheating. See
Engine Coolant Temperature Gauge 0 51.
If the decision is made not to lift the hood
when this warning appears, get service help
right away. Contact your dealer for
additional information.
If the decision is made to lift the hood,
make sure the vehicle is parked on a level
surface.
Vehicle Care
Then check to see if the engine cooling fan
is running. If the engine is overheating, the
fan should be running. If it is not, do not
continue to run the engine, and have the
vehicle serviced.
Caution
Do not run the engine if there is a leak
in the engine cooling system. This can
cause a loss of all coolant and can
damage the system and vehicle. Have
any leaks fixed right away.
If Steam Is Coming from the Engine
Compartment
Warning
Steam and scalding liquids from a hot
cooling system are under pressure.
Turning the pressure cap, even a little,
can cause them to come out at high
speed and you could be burned. Never
turn the cap when the cooling system,
including the pressure cap, is hot. Wait
for the cooling system and pressure cap
to cool.
