9-22 Vehicle Service and Care
4. Then fill the coolant recovery
tank to the FULL mark.
5. Put the cap back on the coolant
recovery tank, but leave the
pressure cap off.
6. Start the engine and let it run
until you can feel the upper
radiator hose getting hot. Watch
out for the engine cooling fan.
7. By this time, the coolant level
inside the radiator filler neck may
be lower. If the level is lower,
add more of the proper coolant
mixture through the filler neck
until the level reaches the base
of the filler neck.
8. Then replace the pressure cap.
At any time during this procedure
if coolant begins to flow out of
the filler neck, reinstall the
pressure cap. Be sure the ears
on the pressure cap are in
line with the vent tube.

Pressure Cap

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.
See Engine Compartment Overview
on page 9-6 for more information
on location.

Engine Overheating

A coolant temperature gage is
located on the vehicle's instrument
panel. See Engine Coolant
Temperature Gage on page 4-19.
Check to see if the electric engine
cooling fan is running. If the engine
is overheating, the fan should be
running. If it is not, the vehicle
needs service.
If no problem is apparent, but the
coolant level is not at or above the
FULL mark, add a 50/50 mixture
of clean, drinkable water and
®
DEX-COOL coolant at the coolant
recovery tank. See Engine Coolant
on page 9-18 for more information
about the proper coolant mixture.
If the coolant inside the coolant
recovery tank is boiling, do not do
anything else until it cools down.
The vehicle should be parked on
a level surface.
