I A CAUTION:
If the overheat warning continues, there's one more
thing you can
try. You can add the proper coolant mix
dire'ctly to the radiator, but b'e sure the cooling system is
cool before you do it.
You can be burned if you spill coolant
on hot
engine parts. Coolant contains ethylene glycol
and it will burn
if the engine parts are hot
enough. Don't spill coolant
on a hot engine.
When the coolant
in the coolant recovery tank is at the
FULL COLD mark, start your vehicle. 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.

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.
