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. 5-16

How
to
Add
Coolant
to
the
Radiator
1.
You can remove the
radiator pressure cap when
the
cooling
system,
including
the

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

some
pressure left.
2.
Then keep
turning
the
pressure cap, but
now
push
down
as
you
turn it.
Remove the
pressure cap.
