When you decide it’s safe to lift the hood, here’s what you’ll see:
Coolant recovery tank
7 Radiator pressure cap
7 Electric engine fans
’ A CAUTION: I
An 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.

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.

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 to the left 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.

5. Put the cap back
on the coolant
recovery tank, but
leave the radiator
pressure cap
off.
6. Start the engine
and let it run
until
you can feel the
upper radiator
hose getting hot.
Watch out for the
engine fans.
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.

To Check Coolant:
When your engine
is
cold, the coolant level
should be at “FULL
COLD,” or a little
higher. When your
engine is
warm, the
level should be
up to
“FULL
HOT,” or a
little higher.
To Add Coolant: If you need more coolant, add the proper mix at the
coolant recovery tank.
A CAUTION: I
lhrning the radiator pressure cap when the engine and radiator si:;
-z. *?’
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 q little -- when tken le and
radiator are hot.

A CAUTION:
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 enougl- spill coolant on
a hot e-yine.
RADUTOR PRESSURE CAP
I-
_I
must be tightly Installed to prevent coolant loss and possible
engine
damage from overheating. Be sure the arrows on the c
line up with the overflow tube on the radiator filler neck .L
When you replace your radiator pressure cap, an ACS cap is
recommended.
THERMOSTAT
Engine coolant temperature is controlled by a thermostat in the engine
coolant system. The thermostat stops the
flow of coolant through the
radiator until the coolant reaches a preset temperature.
When you replace your thermostat, an
AC@ thermostat is recommended.
