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.)
2.
Then keep turning the pressure cap,
but
now push
down as you turn it. Remove
the
pressure
cap.
If
you hear a hiss, wait for that to stop.
A
hiss
means there is still some pressure left.
