4. Then fill the coolant recovery tank to the
COLD FILL mark.
5. Put the cap back on the coolant recovery tank,
but leave the radiator pressure cap off.6. Start the engine and let it run until you can
feel the upper radiator hose getting hot.
Watch out for the engine cooling 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 DEX-COOL
®
coolant mixture 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.

Notice:
When using concentrated washer uid,
follow the manufacturer’s instructions
for adding water.
Do not mix water with ready-to-use washer
uid. Water can cause the solution to
freeze and damage your washer uid tank
and other parts of the washer system.
Also, water does not clean as well
as washer uid.
Fill the washer uid tank only
three-quarters full when it is very cold.
This allows for uid expansion if freezing
occurs, which could damage the tank if
it is completely full.
Do not use engine coolant (antifreeze) in
your windshield washer. It can damage
the vehicle’s windshield washer system
and paint.
Brakes
Brake Fluid
The brake master
cylinder reservoir is
filled with DOT-3 brake
fluid. SeeEngine
Compartment Overview
on page 302for the
location of the reservoir.
There are only two reasons why the brake fluid
level in the reservoir might go down. The first
is that the brake fluid goes down to an acceptable
level during normal brake lining wear. When
new linings are put in, the fluid level goes back
up. The other reason is that fluid is leaking out of
the brake system. If it is, you should have the
brake system fixed, since a leak means that
sooner or later the brakes will not work well.
So, it is not a good idea to top off the brake fluid.
Adding brake fluid will not correct a leak.

Tire Terminology and Denitions
Air Pressure:The amount of air inside the tire
pressing outward on each square inch of the
tire. Air pressure is expressed in pounds
per square inch (psi) or kilopascal (kPa).
Accessory Weight:This means the combined
weight of optional accessories. Some examples of
optional accessories are, automatic transmission,
power steering, power brakes, power windows,
power seats, and air conditioning.
Aspect Ratio:The relationship of a tire’s height
to its width.
Belt:A rubber coated layer of cords that is
located between the plies and the tread. Cords
may be made from steel or other reinforcing
materials.
Bead:The tire bead contains steel wires wrapped
by steel cords that hold the tire onto the rim.
Bias Ply Tire:A pneumatic tire in which the plies
are laid at alternate angles less than 90 degrees
to the centerline of the tread.Cold Tire Pressure:The amount of air pressure in
a tire, measured in pounds per square inch (psi) or
kilopascals (kPa) before a tire has built up heat
from driving. SeeInation - Tire Pressure on
page 354.
Curb Weight:This means the weight of a motor
vehicle with standard and optional equipment
including the maximum capacity of fuel, oil, and
coolant, but without passengers and cargo.
DOT Markings:A code molded into the sidewall
of a tire signifying that the tire is in compliance
with the U.S. Department of Transportation (DOT)
motor vehicle safety standards. The DOT code
includes the Tire Identification Number (TIN),
an alphanumeric designator which can also identify
the tire manufacturer, production plant, brand,
and date of production.
GVWR:Gross Vehicle Weight Rating. See
Loading Your Vehicle on page 261.
GAWR FRT:Gross Axle Weight Rating for the
front axle. SeeLoading Your Vehicle on page 261.

(i)Drain, ush, and rell cooling system. This
service can be complex; you should have
your dealer/retailer perform this service. See
Engine Coolant on page 312 for what to use.
Inspect hoses. Clean radiator, condenser, pressure
cap, and ller neck. Pressure test the cooling
system and pressure cap.
(j)A uid loss in any vehicle system could indicate
a problem. Have the system inspected and
repaired and the uid level checked. Add uid if
needed.
(k)Inspect system. Check all fuel and vapor lines
and hoses for proper hook-up, routing, and
condition. Check that the purge valve works
properly, if equipped. Replace as needed.
(l)If you drive regularly under dusty conditions,
inspect the lter at each engine oil change.
(m)Check system for interference or binding and
for damaged or missing parts. Replace parts
as needed. Replace any components that have
high effort or excessive wear. Do not lubricate
accelerator or cruise control cables.
(n)Visually inspect belt for fraying, excessive
cracks, or obvious damage. Replace belt if
necessary.Owner Checks and Services
These owner checks and services should be
performed at the intervals specified to help
ensure the safety, dependability, and emission
control performance of your vehicle. Your
GM Goodwrench
®dealer can assist you with
these checks and services.
Be sure any necessary repairs are completed at
once. Whenever any fluids or lubricants are added
to your vehicle, make sure they are the proper
ones, as shown inRecommended Fluids and
Lubricants on page 415.
At the First 100, 1,000 and 6,000 Miles
(160, 1 600 and 10 000 km)
For vehicles with dual wheels, check dual wheel
nut torque. For proper torque, seeCapacities
and Specications on page 398.

At Each Fuel Fill
It is important to perform these underhood checks
at each fuel ll.
Engine Oil Level Check
Check the engine oil level and add the proper oil
if necessary. SeeEngine Oil (Gasoline Engine)
on page 303for further details.
Notice:It is important to check the engine
oil regularly and keep it at the proper
level. Failure to keep the engine oil at the
proper level can cause damage to the engine
not covered by your warranty.
Engine Coolant Level Check
Check the engine coolant level and add
DEX-COOL®coolant mixture if necessary. See
Engine Coolant on page 312for further details.
Windshield Washer Fluid Level Check
Check the windshield washer fluid level in
the windshield washer fluid reservoir and add
the proper fluid if necessary.
At Least Once a Month
Tire Ination Check
Inspect your vehicle’s tires and make sure they
are inflated to the correct pressures. Do not forget
to check the spare tire. SeeInation - Tire
Pressure on page 354. Check to make sure the
spare tire is stored securely. SeeChanging a Flat
Tire on page 366.
Tire Wear Inspection
Tire rotation may be required for high mileage
highway drivers prior to the Engine Oil Life System
service notification. Check the tires for wear
and, if necessary, rotate the tires. SeeTire
Inspection and Rotation on page 356.
