When you decide it’s safe to lift the hood, here’s what
you’ll see:
A. Coolant Recovery Tank
B. Radiator Pressure Cap
C. Engine Fan(s)
A CAUTION: I
If your vehicle has air conditioning, the auxiliary
electric fan under the hood can start up even
when the engine
is not running and can injure
you. Keep hands, clothing and tools away from
any underhood electric fan.
If the coolant inside the coolant recovery tank is boiling,
don’t do anything else until it cools down.

system can blow @ut 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.

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 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.

off.

run until you can feel the
upper radiator hose
getting hot. Watch out
for the engine fan(s).
7. By this time the coolant level inside the radiator
filler neck may
be lower. If the level is lower, add
more
of the proper mix through the filler neck until
the level reaches the base
of the filler neck.
8. Then replace the pressure cap. At any time during
this procedure if coolant begins to
flow out of the
filler neck, reinstall
the pressure cap. Be sure the
arrows on the pressure cap line up like this.

The coolant recovery tank is located on the passenger side at the rear corner
of the engine compartment.
When your engine
is cold, the coolant level should be at
the
COLD mark, or a little higher. When your engine is
warm, the level should be up to the HOT mark, or a
little higher.
If you need more coolant, add the proper mix at the
coolant
recovery tank.
A CAUTION:
' Turning the radiator pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to
blow out and burn you badly.
With the coolant recovery tank, you will almost
never have to add coolant at the radiator.
Never turn the radiator pressure cap
-- even a
~ little -- when the engine and radiator are hot.
Add coolant mix at the recovery tank, but be careful not
to spill
it.
AUTION: 0
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.
