Coolant Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at
ADD, 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.)
k!, CAUTICJ:
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 5W50 mix of clean
water and
DEX-COOL TM antifreeze.
I 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.

Downloaded from www.Manualslib.com manuals search engine 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
enough. Don’t spill coolant on a hot engine.
When the coolant in the coolant recovery tank is at
ADD, 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
cool before you do it.

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.

of the filler neck.
4. Then fill the coolant recovery tank to the ADD mark.
5. 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 fan.
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.

To open the hood, first pull
the handle inside the vehicle
on the lower left side of the
instrument panel.
Then
go to the front of the vehicle and release the
secondary hood release. Lift
the hood, release the hood prop from its retainer and
put the hood prop into the slot in the hood. You may
have a lamp that comes on when you lift the hood.
-
A CAUTION:
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.

If the level is below the bottom of the filler plug hole,
you’ll need to add some lubricant.
If the differential is at operating temperature (warm),
add enough lubricant
to raise the level to the bottom of
the filler plug hole. If
the differential is cold, add enough lubricant to raise
the level
to 1/2 inch (12 mm) below the filler plug hole.
What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. See “Recommended Fluids
and
Lubricants’’ in the Index.
Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL R’l (orange-colored, silicate-free) engine
coolant. This coolant is designed to remain in your
vehicle for
5 years or 100,000 miles ( 166 000 km),
whichever occurs first.
The following explains your cooling system and
how
to add coolant when it is low. If you have a problem
with engine overheating, see “Engine Overheating”
in the Index.

Downloaded from www.Manualslib.com manuals search engine A 50/50 mixture of water and the proper coolant for
your vehicle will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 “F ( 129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
0 Let the warning lights and gages work as
they should.
NOTICE:
~~ ~~~~ ~ ~~
When adding coolant it is important that you use
DEX-COOL (orange-colored, silicate-free)
coolant meeting GM Specification 6277M.
If silicated coolant is added to the system,
premature engine, heater core or radiator
corrosion may result. In addition, the engine
coolant
will require change sooner -- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. What to
Use
Use a mixture of one-half
clean water (preferably
distilled) and one-half DEX-COOL (orange-colored,
silicate-free) antifreeze that meets GM Specification
6277M’ which won’t damage aluminum parts. Use
GM Engine Coolant Supplement (sealer) (GM Part
No. 3634621) with any complete coolant change. If you
use this mixture, you don’t need to add anything else.
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 (orange-colored,
silicate-free) antifreeze.
