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.
