Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They
are under pressure, and if you turn the radiator
pressure cap
--
even a little
--
they can come out
at high speed. Never turn the cap when the
cooling system, including the radiator pressure
cap, is hot. Wait for the cooling system and
radiator pressure cap to cool if you ever have to
turn the pressure cap.
How
to
Add
Coolant to the Radiator
P
I.
You
can remove the pressure cap when the cooling
system, including the 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.
