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.
2.
Then keep turning the pressure cap,
but
now push
down as you turn it. Remove the pressure cap.
