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
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.

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

is not running.
Keep hands, clothing and tools away from any

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.

Refer to the Maintenance Schedule to determine what
kind
of transaxle fluid to use. See “Recommended
Fluids and Lubricants”
in the Index.
If the fluid
level is low, add only enough of the proper
fluid to bring the level into the cross-hatched area on
the dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough fluid at the
dipstick hole to bring
it to the proper level. It doesn’t
take much fluid, generally less than
a pint (OSL).
Don ’t overfill. We recommend you use only fluid
labeled DEXRON@-111, because fluid with that
label is made especially for your automatic transaxle.
Damage caused by fluid other than DEXRON@-I11
is
not covered by your new vehicle warranty.
0 After adding fluid, recheck the fluid level as
described under “How to Check.”
0 When the correct fluid level is obtained, push the
dipstick back
in all the way. The cooling
system in your vehicle is filled with new
DEX-COOL
TM (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
or if you need to add coolant to your
radiator, see “Engine Overheating”
in the Index.
A 50/50 mixture of water and the proper coolant for
your Chevrolet will:
0 Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights and gages work as they
should.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
When adding coolant it is important that you use
DEX-COOL
TM (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 TM (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
TM (orange-colored,
silicate-free) antifreeze.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
If you use an improper coolant mix, your
engine could overheat and be badly damaged.
The repair cost wouldn’t be covered by your
warranty.
Too much water in the mix can freeze
and crack the engine, radiator, heater core and
other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
I NOTICE:
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.
Checking Coolant
r-
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.
