How to Add Coolant to the Radiator
(V8 Engine Only)
NOTICE:
The LTl Engine (Code P) has a specific radiator
fill procedure. Failure to follow this procedure
could cause your engine to overheat and be
severely damaged.
1. You can remove the radiator pressure cap when the
cooling system, including the radiator pressure cap and
upper radiator hose, is no longer hot.
T u r n
the pressure
cap slowly counterclockwise until it first stops. (Don't
press down while turning the pressure cap.)
If you hear a hiss, wait for that to stop. A hiss means
there is still some pressure left.
2. Then keep turning the pressure cap, but now push
down as you turn
it.
Remove the pressure cap.
