How
to
Add
Coolant
to
the
Radiator
I
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.
