Cooling System
When you decide it’s safe to lift the hood, here’s what
you’ll see:
An electric engine cooling 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.

' A 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
I NOTICE:
Your engine has a specific radiator fill procedure.
Failure to follow this procedure could cause your
engine to overheat and be severely damaged.
. . 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.
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.

Then fill the coolant recovery tank to the COLD
mark on the overflow hose in the coolant bottle.
Put the cap back on the coolant recovery tank, but
leave the pressure cap
off.
8. Start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch
out for the
engine cooling fans.
9. By this time, the coolant level inside the radiator
filler neck may be lower.
If the level is lower, add
more of the proper
DEX-COOL@ coolant mixture
through the filler neck until the level reaches the
base of the filler neck.

Adding Coolant
If you need more coolant, add the proper DEX-COOL@
coolant mixture ut the coolant recovery tank, but be
careful not to spill it.
If the coolant recovery tank is completely empty, add
coolant
to the radiator. (See “Engine Overheating” in
the Index.)
nrning 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.
b, CAUTIOI.. I
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.

Radiator Pressure Cap NOTICE:
Your radiator cap is a 15 psi (105 kPa)
pressure-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating. Be sure the arrows on the cap line up with the overflow tube on the radiator
filler neck.
When you replace your radiator pressure cap, an AC@
cap is recommended.
Power Steering Fluid
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.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear an unusual noise.
A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
