How to Add Fluid Engine Coolant
Refer to the Maintenance Schedule to determine what
kind of transaxle fluid to use. See
Part D:
Recommended Fluids and Lubricants on page 6-15.
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 one
pint
(0.5 L). Don’t overfill.
Notice: We recommend you use only fluid labeled
DEXRON@-Ill, because fluid with that label is
made especially for your automatic transaxle.
Damage caused by fluid other than DEXRON@-Ill is
not covered by your new vehicle warranty.
3. After adding fluid, recheck the fluid level as
described under “How to Check,” earlier in this
section. The
cooling system in your vehicle is filled with
DEX-COOL@ engine coolant. This coolant is designed
to remain in your vehicle for
5 years or 150,000 miles
(240
000 km), whichever occurs first, if you add
only extended life coolant.
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 on
page
5-28.
A 50/50 mixture of clean, drinkable water and
DEX-COOL@ coolant 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.
Let the warning lights and gages work as they
should.
4. When the correct fluid level is obtained, push the
dipstick back in all the way.

Notice: When adding coolant, it is important that
you use only DEX-COOL@ (silicate-free) coolant.
If coolant other than DEX-COOL@ 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.
Damage caused by the use of coolant other
than DEX-COOL@
is not covered by your new vehicle
warranty.
What to Use
Use a mixture of one-half clean, drinkable water and
one-half
DEX-COOL@ coolant which won’t damage
aluminum parts.
If you use this coolant mixture,
you don’t need
to add anything else. Adding
a plain water
to your cooling
system can be dangerous. Plain water, or
some other
liquid such as aicohol, can boil
before the proper coolant mixture will. Your
vehicle’s coolant warning system
is set for the
proper coolant mixture. With plain water or the
wrong mixture, 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 mixture of clean,
drinkable water and DEX-COOL@ coolant.
Notice: If you use an improper coolant mixture,
your engine could overheat and be badly damaged.
The repair cost wouldn’t be covered by your
warranty. Too much water
in the mixture can freeze
ana crack ihe engine, raiiiaiur, bakr
other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
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.

Coolant Surge Tank Pressure Cap
The cooling system pressure cap is located on the
surge tank.
Notice: Your cooling system pressure cap is a
pressure-type cap and must be tightly installed to
prevent coolant
loss and possible engine damage
from overheating.
Engine Overheating
You will find a coolant temperature gage on your
vehicle’s instrument panel. Your Driver Information
Center (DIC) will also display messages about engine
overheating. See
Engine Coolant Temperature Gage on
page 3-38.
Overheated Engine Protection
Operating Mode
If an overheated engine condition exists and the
message HOT STOP
ENGINE is displayed, an overheat
protection mode which alternates firing groups of
cylinders helps prevent engine damage. In this mode,
you will notice a
loss in power and engine performance.
This operating mode allows your vehicle to be driven
to a safe place in an emergency. Driving extended miles
(km) and/or towing a trailer in the overheat protection
mode should be avoided.
Notice: After driving in the overheated engine
protection operating mode, to avoid engine damage,
allow the engine to cool before attempting any
repair. The engine oil will be severely degraded. Repair the cause of coolant
loss, change the oil and
reset the oil life system. See “Engine
Oil” in the
Index.

ProCarManuals.com

If the coolant inside the coolant recovery tank is boiling,
don’t do anything else until it cools down. The vehicle
should be parked on a level surface.
A low coolant level should be indicated by a LOW
ENGINE COOLANT message on the Driver Information
Center.
If it is, you may have a leak at the pressure
cap or
in the radiator hoses, heater hoses, radiator,
water pump or somewhere else in the cooling system. Heater
and radiator hoses, and other engine
parts, can be very hot. Don’t touch them.
If you
do, you can be burned.
Don’t run the engine if there is a leak. If you
run the engine,
it could lose all coolant. That
could cause an engine fire, and you could be
burned. Get any leak fixed before you drive the
vehicle.
If there seems to be no leak, with the engine on, check
to see
if the electric engine cooling fans are running.
If the engine is overheating, both fans should be
running.
If they aren’t, your vehicle needs service.
Notice: Engine damage from running your engine
without coolant isn’t covered by your warranty.
See “Overheated Engine Protection Operating
Mode’’ in the Index for information on driving to a
safe place
in an emergency.

1 Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil before the proper coolant mixture will. Your
vehicle’s coolant warning system is set for the proper coolant mixture.
CAUTION: (Continued)
I I
With plain water or the wrong mixture, 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 mixture of clean, drinkable water and
DEX COOL@ coolant.
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
IT-:-’=- e.
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.

What to Add Notice:
When you do need brake fluid, use only DOT-3 brake
fluid. Refer
to Part D: Recommended Fluids and
Lubricants on page
6-75. Use new brake fluid from a
sealed container only.
Always clean the brake fluid reservoir cap and the area
around the cap before removing it. This will help
keep dirt from enteri-- the reservoir.
With the wrong kind of fluid in your brake
system, your brakes may not work well, or
they may not even work at all. This could
cause a crash. Always use the proper brake
fluid.
Using the wrong fluid can badly damage brake
system parts. For example, just a few drops of
mineral-based oil, such as engine oil, in your
brake system can damage brake system
parts
so badly that they’ll have to be replaced.
Don’t let someone put in the wrong kind of fluid.
9 If you spill brake fluid on your vehicle’s painted
surfaces, the paint finish can
be damaged. Be
careful not to spill brake fluid on your vehicle.
If
you do, wash it off immediately. See
“Appearance Care” in the Index.

Part A: Scheduled Maintenance
Services
This part contains engine oil scheduled maintenance
which explains the engine oil life system and how
it indicates when to change the engine oil and filter.
Also, listed are scheduled maintenance services which
are to be performed at the mileage intervals specified.
Using Your Maintenance Schedule
We at General Motors want to keep your vehicle in good
working condition. But we don’t know exactly how
you’ll drive it. You may drive short distances only a few
times a week. Or you may drive long distances all
the time in very hot, dusty weather. You may use your
vehicle in making deliveries. Or you may drive it to
work, to do errands or in many other ways.
Because of the different ways people use their vehicles,
maintenance needs may vary. You may need more
frequent checks and replacements.
So please read the
following and note how you drive. If you have
questions on how to keep your vehicle in good condition,
see your dealer. This part tells
you the maintenance services you should
have done and when you should schedule them.
When you go to your dealer for your service needs,
you’ll know that GM-trained and supported service
people will perform the work using genuine GM parts.
The proper fluids and lubricants to use are listed in
Part
D. Make sure whoever services your vehicle uses
these.
All parts should be replaced and all necessary
repairs done before you or anyone else drives the
vehicle.
This schedule is for vehicles that:
carry passengers and cargo within recommended
limits. You will find these on your vehicle’s
Tire-Loading Information label. See
Loading Your
Vehicle on page 4-34.

Footnotes
t The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior to
the completion of the vehicle
's useful life. We, however,
urge that all recommended maintenance services be
periormea at tne inuicateti intervais anti tne
maintenance be recorded.
@ Whenever the tires are rotated, the Check Tire
Pressure System must be reset.
+A good ti.me to check your brakes is duri.ng tire
rotation. See Brake System Inspection on page 6-14.
Engine Oil Scheduled Maintenance
Change engine oil and filter as indicated by the GM
Oil Life SystemTM (or every 12 months, whichever
occurs first). Reset the system.
Your vehicle has a computer system that lets you know
when to change the engine oil and filter. This is
based on engine revolutions and engine temperature,
and not on mileage. Based on driving conditions,
the mileage at which an oil change will be indicated can
vary considerably. For the oil life system to work
properly, you must reset the system every time the oil is
changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is
necessary. A CHANGE
OIL SOON light will come on.
Change your oil as
soon as possible within the next two
times you stop for fuel.
It is possible that, if you are
driving under the best conditions, the oil life system may
not indicate that an oil change is necessary for over a
year. However, your engine oil and filter must be
must be reset. It is
also important to check your oil
regularly and keep it at the proper level.
If the system is ever reset accidentally, you must
change your oil at
3,000 miles (5 000 km) since your
last oil change. Remember to reset the
oil life system
whenever the oil is changed. See
Engine Oil on
page
5-15 for information on resetting the system.
