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. Do not 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.
3. Fill the radiator with the proper DEX-COOL
®
coolant mixture, up to the base of the filler
neck. See Engine Coolant on page 5-27 for more
information about the proper coolant mixture.
