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.
