If you haven’t found a problem yet, but the coolant level
isn’t at
the COLD mark, add a 50/50 mixture of
clean water (preferably distilled) and DEX-COOL TM
(orange-colored, silicate-free) antifreeze at the coolant
recovery tank. (See “Engine Coolant” in the
Index for
more information.)
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warning
system is set for the proper coolant mix. With
plain water or the wrong mix, your engine could
get too hot but
you wouldn’t get the overheat
warning. Your engine could catch fire and you or
others could be burned. Use a
50/50 mix of clean
water and
DEX-COOL TM antifreeze.
1 NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts. Use the recommended coolant and the proper
coolant mix.

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
COLD mark, start your vehicle.
If the overheat warning continues, there's one more
thing you can try.
You can add the proper coolant mix
directly to the radiator, but
be sure the cooling system is
cool before you do it.

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.

I NOTICE:
lant to the ldiator
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 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

will burn if the engine parts are hot

valve, close the valve. Otherwise, close the valves after
the radiator
is filled.
5. Rinse or wipe any spilled coolant from the engine
and compartment.
6. Then fill the coolant recovery tank to the COLD mark.
7. Put the cap back on the coolant recovery tank, but
leave the radiator pressure cap off.

upper radiator hose getting hot. Watch out for the
engine fans.
9. By this time the coolant level inside the r' d d' lator
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.
10. 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.
11. Check the coolant in the recovery tank. The level in
the coolant recovery tank should be at the HOT
mark when the engine is hot or at the COLD mark
when
the engine is cold.

An' electric fan under the hood'can' start up and
injure you even when the engine
is not running.
Keep hands, clothing and tools away from any
underhood electric fan.
I
Things that burn can get on hot engine parts and
start
a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber. You or others
could be burned. Be careful not to drop or spill
things that will burn onto a hot engine.
Hood Release
To open the'hood, first pull
the handle inside the vehicle.
Then
go to the front of the
vehicle and release the secondary hood release.
Lift the hood.
