the coolant surge
tank pressure
cap when the
cooling system,
including the
coolant surge
tank pressure cap
and upper radiator
hose, is no longer
hot.
Turn the pressure cap slowly to the left 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 cap, but now
push down as you
turn it. Remove
the pressure cap.
