4. With the coolant surge tank pressure cap off,
start the engine and let it run until you can feel
the upper radiator hose getting hot. Watch out
for the engine cooling fan.
By this time, the coolant level inside the coolant
surge tank may be lower. If the level is lower
than the COLD FILL line, add more of the proper
mixture to the coolant surge tank until the level
reaches the COLD FILL line.
5. Then replace the pressure cap. Be sure the
pressure cap is hand-tight and fully seated.
See your dealer/retailer, if necessary.
Engine Overheating
The vehicle has an indicator to warn of engine
overheating.
You will find an engine coolant temperature warning
light on your vehicle's instrument panel. See Engine
Coolant Temperature Warning Light
on page 426
for
more information.
You may decide not to lift the hood when this warning
appears, but instead get service help right away.
See Roadside Assistance Program on page 87.
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.
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.
