8. By this time, the coolant level inside the radiator
filler port may be lower. If the level is lower, add
more of the proper DEX-COOL
® coolant mixture
through the fill port until the level reaches the base
of the fill port.
9. Then replace the pressure cap. At any time during
this procedure, if coolant begins to flow out of the
fill port, reinstall the pressure cap. Be sure the
pressure cap is hand-tight and fully seated.
10. When the engine has cooled, check the coolant in
the coolant recovery tank. The level in the coolant
recovery tank should be at the COLD FILL line
when the engine is cold.
Engine Overheating
The vehicle has several indicators to warn of engine
overheating.
You will find a coolant temperature warning light and a
coolant temperature gage on your vehicle’s instrument
panel. See Engine Coolant Temperature Warning
Light on page 4-33 and Engine Coolant Temperature
Gage on page 4-34 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 8-6.
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.
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.
