service CHEVROLET KODIAK 2008 Repair Manual

{CAUTION:
Your vehicle, when new, did not include tire
changing equipment or a place to store a tire
in the vehicle. Special tools and procedures
are required if a tire needs to be serviced.
If these tools and procedures are not used,
you or others could be injured or killed while
trying to change or service a truck tire.
Your truck, when new, did not include tire changing
equipment or a place to store a tire in the vehicle. Few
drivers of these vehicles have the necessary equipment
aboard to be able to change a flat tire safely. For
example, you would need a truck jack that can lift
several thousand pounds and a torque wrench that can
generate several hundred foot-pounds (Y)of
twisting force.
{CAUTION:
If you try to put air back into a tire that has run
at, even a tire that was extremely low on air,
the tire can have a sudden air-out. This could
cause you to lose control of the vehicle and
have a serious crash. Do not rell a at or very
low tire with air without rst having the tire
taken off the wheel and checked for damage.
So if you are stopped somewhere by a flat or damaged
tire or wheel, you should get expert help. See
Roadside Assistance Program on page 7-5.

Vehicle Identication
Vehicle Identication Number (VIN)
This is the legal identifier for your vehicle. It appears on
a plate in the front corner of the instrument panel, on
the driver side. You can see it if you look through the
windshield from outside your vehicle. The VIN also
appears on the Certification/Tire and Service Parts labels
and the certificates of title and registration.
Engine Identication
The eighth character in the VIN is the engine code. This
code helps you identify your vehicle’s engine,
specifications, and replacement parts. SeeCapacities
and Specifications on page 5-109for your vehicle’s
engine code.
5-101

Service Parts Identication Label
This label is in a location determined by the body
manufacturer. It is very helpful if you ever need to order
parts. The label has the following information:
•Vehicle Identification Number (VIN)
•Model designation
•Paint information
•Production options and special equipment
Do not remove this label from the vehicle.
Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer/retailer
rst. Some electrical equipment can damage your
vehicle and the damage would not be covered by
your warranty. Some add-on electrical equipment can
keep other components from working as they should.
Add-on equipment can drain your vehicle’s battery, even
if your vehicle is not operating.Your vehicle has an airbag system. Before attempting to
add anything electrical to your vehicle, seeServicing
Your Airbag-Equipped Vehicle on page 1-59.
Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the light switch. An electrical overload will cause the
lights to go on and off, or in some cases to remain off.
If this happens, have your headlamp wiring checked
right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a circuit
breaker inside the motor and a circuit breaker or fuse in
the fuse block. If the motor overheats, the wipers will
stop until the motor cools. If the overload is caused by
an electrical problem, be sure to get it fixed.

Section 6 Maintenance Schedule
6-1

How This Section is Organized
This maintenance schedule is divided into four parts:
“Part A: Scheduled Maintenance Services”explains
what to have done and how often. Some of these
services can be complex, so unless you are technically
qualified and have the necessary equipment, you
should let your dealer/retailer do these jobs.
Your dealer/retailer has trained and supported service
people that will perform the work using genuine parts.
{CAUTION:
Performing maintenance work on a vehicle can
be dangerous. In trying to do some jobs, you
can be seriously injured. Do your own
maintenance work only if you have the required
know-how and the proper tools and equipment
for the job. If you have any doubt, have a
qualied technician do the work. SeeDoing
Your Own Service Work on page 5-6.
If you want to purchase service information, seeService
Publications Ordering Information on page 7-10.“Part B: Owner Checks and Services”tells you what
should be checked and when. It also explains what
you can easily do to keep your vehicle in good condition.
“Part C: Recommended Fluids and Lubricants”
lists some recommended products necessary to help
keep your vehicle properly maintained. These products,
or their equivalents, should be used whether you do the
work yourself or have it done.
“Part D: Maintenance Record”is a place for you to
record and keep track of the maintenance performed on
your vehicle. Keep your maintenance receipts. They
may be needed to qualify your vehicle for warranty
repairs.
6-3

Part A: Scheduled Maintenance
Services
In this part are scheduled maintenance services which
are to be performed at the mileage intervals specified.
Using the Maintenance Schedule
We want to help keep your vehicle in good working
condition. But we do not know exactly how you will drive
it. You might drive very short distances only a few times
a week. Or you might drive long distances all the
time in very hot, dusty weather. You might use your
vehicle in making deliveries or in many other ways.
Because of all the different ways people use their
vehicles, maintenance needs vary. You might need
more frequent checks and replacements. So please read
the following and note how you drive. If you have any
questions on how to keep your vehicle in good condition,
see your dealer/retailer.
This part tells you the maintenance services you should
have done and when to schedule them.
When you go to your dealer/retailer for your service
needs, you will know that trained and supported service
people will perform the work using genuine parts.The proper fluids and lubricants to use are listed in
Part C. 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 limits on your vehicle’s
Certification or Tire Information label. SeeLoading
Your Vehicle on page 4-21.
•are driven on reasonable road surfaces within legal
driving limits.
•use the recommended fuel. SeeGasoline Octane
on page 5-7for gasoline engine vehicles orWhat
Fuel to Use on page 5-9for diesel engine vehicles.
Scheduled Maintenance
Supplements
If your vehicle has a Caterpillar®diesel engine, your
owner manual is supplemented by the Caterpillar®
Diesel Engine Operation & Maintenance Manual. If your
vehicle has an Allison Transmission®, your owner
manual is supplemented by an Allison Transmission®
Operator’s Manual. Always refer to these manuals
for related maintenance services.
6-4

Scheduled Maintenance
The services shown in this schedule up to 100,000 miles
(166 000 km) should be repeated after 100,000 miles
(166 000 km) at the same intervals for the life of
this vehicle. The services shown after 100,000 miles
(166 000 km) should be repeated at the same miles (km)
after those intervals for the life of this vehicle.
Gasoline engine vehicles and some DURAMAX
®diesel
and Isuzu diesel engine vehicles have a computer
that lets you know when to change the engine oil. This
is not based on mileage, but on engine operation and
engine temperature. When the computer has calculated
that the oil needs changing, the Engine Oil Life System
will indicate that a change is necessary. SeeEngine Oil
Life System (Gasoline Engine) on page 5-36orEngine
Oil Life System (DURAMAX
®/Isuzu Diesel Engines) on
page 5-37orEngine Oil Life System (Caterpillar®Diesel
Engine) on page 5-39.
The “Footnotes” at the end of this Maintenance
Schedule further explain maintenance services.
