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.
