If the overheat warning continues, there is one
more thing you can try. You can add the proper
coolant mixture directly to the radiator, but be sure
the cooling system is cool before you do it.
{CAUTION:
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
Notice: Your engine has a specific radiator fill
procedure. Failure to follow this procedure
could cause your engine to overheat and
be severely damaged.
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
counterclockwise. If you hear a hiss, wait for
that to stop. A hiss means there is still
some pressure left, close the cap and wait for
the system to cool down.
