How to Add Coolant to the Radiator

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.
