Check to see if coolant is visible in
the reservoir. If coolant is visible but
the coolant level is below the cold
fill line, there could be a leak in the
cooling system.
How to Add Coolant to the
Coolant Reservoir
If no problem is found, add the
proper DEX-COOL coolant mixture
at the coolant reservoir.
The coolant reservoir pressure cap
can be removed when the cooling
system, including the pressure cap,
is no longer hot.1. Turn the pressure cap counterclockwise and
remove it.
2. Fill the coolant reservoir with the proper mixture to the cold
fill line on the side of the
reservoir.
3. Reinstall the pressure cap tightly.
Check the level in the coolant
reservoir when the cooling system
has cooled down. If the coolant is
not at the proper level, repeat
Steps 1 and 2, then reinstall the
pressure cap. If the coolant still is
not at the proper level when the
system cools down again, see your
dealer.
Engine Coolant
The engine cooling system in the
vehicle is filled with DEX-COOL
engine coolant. The coolant needs
to be replaced every 5 years or
240 000 km (150,000 mi), whichever
occurs first.
The following explains the cooling
system and how to check and add
coolant when it is low. If there is a
problem with engine overheating,
see Engine Overheating 0253.
What to Use
{Warning
Adding only plain water or some
other liquid to the cooling system
can be dangerous. Plain water
and other liquids, can boil before
the proper coolant mixture will.
The coolant warning system is set
for the proper coolant mixture.
With plain water or the wrong
mixture, the engine could get too
hot but you would not get the

Warning (Continued)
overheat warning. The engine
could catch fire and you or others
could be burned. Use a 50/
50 mixture of deionized water and
DEX-COOL coolant.
Use a 50/50 mixture of deionized
water and DEX-COOL coolant.
If using this mixture, nothing else
needs to be added. This mixture:
. Gives freezing protection down
to−37 °C (−34 °F), outside
temperature.
. Gives boiling protection up to
129 °C (265 °F), engine
temperature.
. Protects against rust and
corrosion.
. Will not damage aluminum parts.
. Helps keep the proper engine
temperature.
Caution
If improper coolant mixture,
inhibitors, or additives are used in
the vehicle cooling system, the
engine could overheat and be
damaged. Too much deionized
water or clean drinkable water
can freeze and crack engine
cooling parts. The repairs would
not be covered by the vehicle
warranty. Use only the proper
mixture of engine coolant for the
cooling system. See
Recommended Fluids and
Lubricants 0327.
Never dispose of engine coolant by
putting it in the trash, pouring it on
the ground, or into sewers, streams,
or bodies of water. Have the coolant
changed by an authorized service
center, familiar with legal
requirements regarding used
coolant disposal. This will help
protect the environment and your
health.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
Check to see if coolant is visible in
the coolant surge tank. If the coolant
inside the coolant surge tank is
boiling, do not do anything else until
it cools down. If coolant is visible
but the coolant level is not at or
above the cold fill mark, add a 50/
50 mixture of deionized water and
DEX-COOL coolant at the coolant
surge tank, but be sure the cooling
system is cool before this is done.
See Engine Overheating 0253
The coolant reservoir is located on
the passenger side of the engine
compartment. See Engine
Compartment Overview 0242.
The coolant level should be at or
above the cold fill line on the
coolant surge tank. If it is not, there
could be a leak in the cooling
system.

How to Add Coolant to the
Coolant Surge Tank
{Warning
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.
Caution
This vehicle has a specific
coolant fill procedure. Failure to
follow this procedure could cause
the engine to overheat and be
severely damaged.
{Warning
The electric fans under the hood
can start up even when the
engine is not running and can(Continued)
Warning (Continued)
cause injury. Keep hands,
clothing, and tools away from any
underhood electric fan.
{Warning
Steam and scalding liquids from a
hot cooling system can blow out
and burn you badly. They are
under pressure, and if you turn
the surge tank pressure
cap—even a little —they can
come out at high speed. Never
turn the cap when the cooling
system, including the surge tank
pressure cap, is hot. Wait for the
cooling system and surge tank
pressure cap to cool if you ever
have to turn the pressure cap.
If coolant is needed, add the proper
DEX-COOL coolant mixture at the
coolant surge tank.
The coolant surge tank pressure
cap can be removed when the
cooling system, including the surge
tank pressure cap and upper
radiator hose, is no longer hot. 1. Turn the pressure cap slowly counterclockwise. If a hiss is
heard, wait for that to stop.
A hiss means there is still
some pressure left.
2. Keep turning the cap and remove it.

3. Fill the coolant surge tank withthe proper mixture to the cold
fill line.
4. Replace the pressure cap. Be sure the pressure cap is
hand-tight and fully seated.
Caution
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.
Engine Overheating
The vehicle has an indicator to warn
of engine overheating.
If the decision is made not to lift the
hood when this warning appears,
get service help right away. See
Roadside Service 0336.
If the decision is made to lift the
hood, make sure the vehicle is
parked on a level surface.
Then check to see if the engine
cooling fans are running. If the
engine is overheating, the fans
should be running. If they are not,
do not continue to run the vehicle
and have the vehicle serviced.
Caution
Running the engine without
coolant may cause damage or a
fire. Vehicle damage would not be
covered by the vehicle warranty.
Washer Fluid
What to Use
When adding windshield washer
fluid to the vehicle, be sure to read
the manufacturer's instructions
before use. If operating the vehicle
in an area where the temperature
may fall below freezing, use a fluid
that has sufficient protection against
freezing.
Adding Washer Fluid
Open the cap with the washer
symbol on it. Add washer fluid until
the tank is full. See Engine
Compartment Overview 0242 for
reservoir location.

Caution
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
clearance to the body and
chassis.
{Warning
Never use oil or grease on studs
or the threads of the wheel nuts.
The wheel nuts might come loose
and the wheel could fall off,
causing a crash.
{Warning
Incorrect wheel nuts or improperly
tightened wheel nuts can cause
the wheel to become loose and
even come off. This could lead to(Continued)
Warning (Continued)
a crash. Be sure to use the
correct wheel nuts. If you have to
replace them, be sure to get new
GM original equipment
wheel nuts.
Caution
Improperly tightened wheel nuts
can lead to brake pulsation and
rotor damage. To avoid expensive
brake repairs, evenly tighten the
wheel nuts in the proper
sequence and to the proper
torque specification.
Used Replacement Wheels
{Warning
Replacing a wheel with a used
one is dangerous. How it has
been used or how far it has been
driven may be unknown. It could (Continued)
Warning (Continued)
fail suddenly and cause a crash.
When replacing wheels, use a
new GM original equipment
wheel.
Tire Chains
{Warning
Do not use tire chains. There is
not enough clearance. Tire chains
used on a vehicle without the
proper amount of clearance can
cause damage to the brakes,
suspension, or other vehicle
parts. The area damaged by the
tire chains could cause loss of
control and a crash.
Use another type of traction
device only if its manufacturer
recommends it for the vehicle's
tire size combination and road
conditions. Follow that
manufacturer's instructions. To(Continued)
