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.
