4. Fill the coolant recovery tank to
the FULL COLD mark.
5. Reinstall the cap on the coolant
recovery tank, but leave the
radiator pressure cap off.
6. Start the engine and let it run
until the upper radiator hose can
be felt getting hot. Watch out for
the engine cooling fan.
7. By this time, the coolant level
inside the radiator filler neck
might be lower. If the level is
lower, add more of the proper
DEXCOOL 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.
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 a coolant
temperature gauge displayed on
the instrument panel to warn if the
engine is overheating. See Engine
Coolant Temperature Gauge on
page 510. If the engine is too hot,
the air conditioning might stop
working. This is normal and helps
cool the engine.
If the decision is made not to lift the
hood when the warning appears, but
instead get service help right away.
