How to Add Coolant to the Radiator
1.
You can remove the radiator pressure
cap when the cooling system,
including the radiator pressure cap an(
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 pressure cap,
but now push down
as you turn it.
Remove the pressure cap.
3. Fill the radiator with the proper mix,
up to the base of the filler neck.
