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 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.
