2007 CHEVROLET KODIAK check engine

{CAUTION:
Fans or other moving engine parts can
injure you badly. Keep your hands away
from moving parts once the engine is
running.
5. Check that the jumper cables do not have
loose or missing insulation. If they do, you
could get a shock. The vehicles could
be damaged too.
Before you connect the cables, here are some
basic things you should know. Positive (+)
will go to positive (+) or to a remote positive (+)
terminal if the vehicle has one. Negative (−)
will go to a heavy, unpainted metal engine part
or to a remote negative (−) terminal if the
vehicle has one.Do not connect positive (+) to negative (−)or
you will get a short that would damage
the battery and maybe other parts too. And do
not connect the negative (−) cable to the
negative (−) terminal on the dead battery
because this can cause sparks.
6. Connect the red
positive (+) cable to
the positive (+)
terminal of the dead
battery. Use a
remote positive (+)
terminal if the
vehicle has one.

Other Service Items
Fuel Filter
Fuel Filter/Pressure Regulator
(Gasoline Engines)
The steel fuel filter/pressure regulator is located
near the engine compartment on the driver’s
side frame rail. If your vehicle has a rear steel fuel
tank, the fuel filter/pressure regulator is located
near the rear fuel tank, on the driver’s side frame
rail. SeeScheduled Maintenance on page 363
for recommended service intervals.
If your vehicle is equipped with the optional Davco
spin-on type filter, it is located on the driver’s
side frame rail.
Fuel Filter (Diesel Engines)
If you have a diesel engine, your fuel filter is
located in the engine compartment on the driver’s
side of the vehicle, or along the driver’s side
frame rail. See “Fuel Filter Replacement” earlier in
this section for further information.
Also seeScheduled Maintenance on page 363for
recommended service intervals.
Primary Fuel Filter and Water
Separator
If you have a diesel
engine, you may have
this spin-on filter. It
is located on the driver’s
side frame rail.
It has a clear plastic drain bowl at the bottom.
Check the drain bowl occasionally for any water or
particles.
To drain the bowl, do the following:
1. Shut off the engine.
2. Partially open the drain valve at the bottom of
the filter.

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’s 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 will help you identify your vehicle’s
engine, specifications, and replacement parts.
Service Parts Identication Label
You will find this label in a location determined by
the body manufacturer. It is very helpful if you
ever need to order parts. On this label, you will find
the following:
•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
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.

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.
Fusible Links
A fusible link is a short piece of wire several gauge
sizes smaller than the circuit it protects. It will melt
in an overload situation, opening the circuit.
Your starter and other circuits have these fusible
links. The size is printed on the insulation. If the
insulation is burned beyond recognition, consult
your dealer for the proper size. Replace a fusiblelink with one of the same size and insulation type.
Fusible link insulation is a special purpose
high-temperature material.
Some examples of circuits with fusible links are
the hydraulic brake booster motor feed circuit, the
generator output circuit, and the intake heater
feed circuit in vehicles with a diesel engine.
Power Windows and Other
Power Options
Circuit breakers in the fuse panel protect the power
windows and other power accessories. When the
current load is too heavy, the circuit breaker opens.
This protects the circuit until the current load returns
to normal or the problem is fixed.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected
from short circuits by a combination of fuses, circuit
breakers, maxi-fuses and fusible links. This greatly
reduces the chance of a fire caused by an electrical
problem. There may be a fuse taped to the wiring
harness near the hydraulic brake booster.

Maintenance Schedule
Introduction
Important: Keep engine oil at the proper level
and change as recommended.
Have you purchased the GM Protection Plan? The
Plan supplements your new vehicle warranties.
See your Warranty and Owner Assistance booklet
or your dealer for details.
Maintenance Requirements
Maintenance intervals, checks, inspections and
recommended fluids and lubricants as prescribed
in this manual are necessary to keep your
vehicle in good working condition. Any damage
caused by failure to follow scheduled maintenance
may not be covered by warranty.
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to
keep your vehicle in good working condition, but
also helps the environment. Improper vehicle
maintenance can even affect the quality of the air
we breathe. Improper fluid levels or the wrong
tire inflation can increase the level of emissions
from your vehicle. To help protect our environment,
and to keep your vehicle in good condition, be
sure to maintain your vehicle properly.
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 GM
dealer’s service department do these jobs.
Your GM dealer has GM-trained and supported
service people that will perform the work using
genuine GM parts.

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 at General Motors want to help keep
your vehicle in good working condition. But we do
not know exactly how you will drive it. You may
drive very 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 in many other ways.
Because of all the different ways people use their
vehicles, maintenance needs vary. You may
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.
This part tells you the maintenance services you
should have done and when to schedule them.When you go to your dealer for your service
needs, you will 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 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 238.
•are driven on reasonable road surfaces within
legal driving limits.
•use the recommended fuel. SeeGasoline
Octane on page 251for gasoline engine
vehicles orWhat Fuel to Use on page 253
for diesel engine vehicles.
