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.
If
you hear a hiss, wait for that to stop.
A
hiss
means there is still some pressure left.
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.)
2.
Then keep turning the pressure cap, but now push
down as you turn it. Remove the pressure cap.
