How to Add Coolant to the Radiator
NOTICE:
Your engine has a specific radiator fill procedure.
Failure to follow this procedure could cause your
engine to overheat and be severely damaged.
The radiator pressure cap is located on the passenger’s
side in the front of the engine compartment, near the
battery and the diagonal cross brace. See “Engine
Compartment Overview” in the Index for more
information on location.
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. (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.
