How to Add Coolant to the Radiator
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, radiator including
the 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.)
2. Then keep turning the pressure cap, but now push
down
as you turn it. Remove the pressure cap.
