4. Then fill the coolant recovery tank to the COLD
FILL line.
5. Install the coolant recovery tank cap and the
pressure cap. After a day or two of driving, when
the engine is cold, check the coolant level in the
recovery tank. If it is low, refill it to the COLD
FILL line.
If the coolant in the recovery tank is constantly low, you
should have a dealer service department inspect the
vehicle for leaks.
Notice: If the pressure cap is not tightly installed,
coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.
Engine Overheating
The vehicle has several indicators to warn of engine
overheating.
You will find a warning light about a hot engine as well
as an engine coolant temperature gauge on the
instrument panel cluster.
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 while driving with
no coolant, the vehicle can be badly damaged. The
costly repairs would not be covered by the vehicle
warranty. See Overheated Engine Protection
