How to Add Coolant to the Radiator
(3.8L V6 Engine)
Notice: Your engine 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.
Turn the pressure cap slowly counterclockwise until
it first stops. Do not 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.
