Engine Coolant
The cooling system in your vehicle
is lled with DEX-COOL®engine
coolant. This coolant is designed to
remain in your vehicle for ve years
or 150,000 miles (240 000 km),
whichever occurs rst, if you add
only DEX-COOL
®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 9-18.
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.
Notice:Using coolant other than
DEX-COOL
®can cause premature
engine, heater core, or radiator
corrosion. In addition, the engine
coolant may require changing
sooner, at the rst maintenance
service after each 30,000 miles
(50 000 km) or 24 months,
whichever occurs rst. Any
repairs would not be covered by
the vehicle warranty. Always
use DEX-COOL
®(silicate-free)
coolant in the vehicle.
What to Use
Use a mixture of one-half clean,
drinkable water and one-half
DEX-COOL
®coolant which will not
damage aluminum parts. If you
use this coolant mixture, you do not
need to add anything else.
{CAUTION
Adding only plain water to the
cooling system can be dangerous.
Plain water, or some other liquid
such as alcohol, can boil before
the proper coolant mixture will.
The vehicle’s coolant warning
system is set for the proper
coolant mixture. With plain water
or the wrong mixture, the engine
could get too hot but would not
get the overheat warning. The
engine could catch re and you or
others could be burned. Use a
50/50 mixture of clean, drinkable
water and DEX-COOL
®coolant.

Notice:If an improper coolant
mixture is used, the engine could
overheat and be badly damaged.
The repair cost would not be
covered by the vehicle warranty.
Too much water in the mixture
can freeze and crack the engine,
radiator, heater core, and
other parts.
Notice:If you use extra
inhibitors and/or additives in
your vehicle’s cooling system,
you could damage your vehicle.
Use only the proper mixture of
the engine coolant listed in
this manual for the cooling
system. See Recommended
Fluids and Lubricants in the
Maintenance and Limited
Warranty and Owner Assistance
Information manual.Checking Coolant
The coolant reservoir is located in
the engine compartment on the
driver’s side of the vehicle.
SeeEngine Compartment Overview
on page 9-6for more information
on location.
{CAUTION
Turning the coolant reservoir
pressure cap when the engine
and radiator are hot can allow
steam and scalding liquids to blow
out and burn you badly. Never
turn the coolant reservoir pressure
cap – even a little – when the
engine and radiator are hot.
The vehicle must be on a level
surface. When your engine is cold,
the coolant level should be at
the KALT/COLD line.
Do not overll the coolant reservoir.
Too much coolant can result in
an overow condition when the
uid is hot.

Adding Coolant
If you need more coolant, add the
proper DEX-COOL®coolant mixture
at the coolant reservoir, but only
when the engine is cool. If the
coolant reservoir is empty, a
special ll procedure is necessary.
SeeCooling System on page 9-12
for instructions on “How to Add
Coolant to the Coolant Reservoir.”
{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. Do not spill
coolant on a hot engine.
When replacing the pressure cap,
make sure it is hand-tight and
fully seated.
Pressure Cap
Notice:If the pressure cap is not
tightly installed, coolant loss
and possible engine damage may
occur. Be sure the cap is
properly and tightly secured.
SeeEngine Compartment Overview
on page 9-6for more information
on location.
Engine Overheating
There is an engine coolant
temperature warning light on your
vehicle’s instrument panel. See
Engine Coolant Temperature
Warning Light on page 4-18for
more information.
If Steam Is Coming From
Your Engine
{CAUTION
Steam from an overheated engine
can burn you badly, even if you
just open the hood. Stay away
from the engine if you see or hear
steam coming from it. Just turn it
off and get everyone away from
the vehicle until it cools down.
Wait until there is no sign of
steam or coolant before you open
the hood.
If you keep driving when your
engine is overheated, the liquids in
it can catch re. You or others
could be badly burned. Stop your
engine if it overheats, and get out
of the vehicle until the engine
is cool.

Wheel Replacement
Replace any wheel that is bent,
cracked or badly rusted or corroded.
If the wheel bolts keep coming
loose, the wheel and wheel bolts
should be replaced. If the wheel
leaks air, replace it (except some
aluminum wheels, which can
sometimes be repaired). See your
dealer/retailer if any of these
conditions exist.
Your dealer/retailer will know the
kind of wheel you need.
Each new wheel should have the
same load-carrying capacity,
diameter, width, offset and be
mounted the same way as the
one it replaces.
If you need to replace any of the
wheels or wheel bolts, replace them
only with new GM original equipment
parts. This way, you will be sure to
have the right wheel and wheel bolts
for the vehicle.{CAUTION
Using the wrong replacement
wheels or wheel bolts on your
vehicle can be dangerous. It could
affect the braking and handling of
the vehicle, make the tires lose air
and make you lose control of
the vehicle. You could have a
collision in which you or others
could be injured. Always use the
correct wheel and wheel bolts for
replacement.
Notice:The wrong wheel can
also cause problems with bearing
life, brake cooling, speedometer
or odometer calibration,
headlamp aim, bumper height,
vehicle ground clearance, and tire
or tire chain clearance to the
body and chassis.
SeeChanging a Flat Tire on
page 9-61for more information.
Used Replacement Wheels
{CAUTION
Putting a used wheel on the
vehicle is dangerous. You cannot
know how it has been used or
how far it has been driven.
It could fail suddenly and cause a
crash. If you have to replace a
wheel, use a new GM original
equipment wheel.

Maintenance Footnotes
(a)A fluid loss in any vehicle system
could indicate a problem. Have the
system inspected and repaired
and the fluid level checked. Add fluid
if needed.
(b)If driving regularly under dusty
conditions or in high-polluted
regions, replace the filter at each
engine oil change.
(c)Inspect brake lines and hoses for
proper hook-up, binding, leaks,
cracks, chafing, etc. Inspect disc
brake pads for wear and rotors for
surface condition. Inspect other
brake parts, including calipers,
parking brake, etc.
(d)Inspect front and rear suspension
and steering system for damaged,
loose, or missing parts or signs of
wear. Inspect power steering cables
for proper hook-up, binding, cracks,
chafing, etc. Inspect power steering
hydraulic lines and hoses for proper
hook-up, binding, leaks, cracks,
chafing, etc.(e)Inspect hoses and have them
replaced if they are cracked,
swollen, or deteriorated. Inspect all
pipes, fittings and clamps; replace
with genuine parts as needed.
To help ensure proper operation,
a pressure test of the cooling system
and pressure cap and cleaning
the outside of the radiator and
air conditioning condenser is
recommended at least once a year.
(f)Inspect wiper blades for wear,
cracking, or contamination.
Clean the windshield and wiper
blades, if contaminated. Replace
wiper blades that are worn or
damaged. See Windshield Wiper
Blade Replacement on page 9-21
and “Windshield and Wiper Blades”
in Exterior Cleaning on page 9-76.
(g)Make sure the safety belt
