How
to
Add
Coolant
to
the
Radiator
A
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.
