How to Add Coolant to the Radiator
You can remove the
radiator pressure cap
when the cooling
system, including
the radiator pressure
cap and upper
radiator hose, is
no longer hot.
1. 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.
