Downloaded from www.Manualslib.com manuals search engine Headlight Wiring
The headlight wiring is protected by a
circuit breaker in the fuseblock. An
electrical overload will cause the lights
to go on and off, or in some cases
to
remain off. If this happens, have your
headlight system checked right away.
To access the headlight circuit breaker,
squeeze the plastic clip together and
remove.
Windshield Wipers
The windshield wiper motor is
protected by
a circuit breaker and a
fuse. If the motor overheats due to
heavy snow, etc., the wiper will stop
until the motor cools.
If the overload is
caused by some electrical problem, have
it fixed.
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 and closes, protecting the circuit
until the problem is fixed.

A Word About Maintenance
We at General Motors want to help you
keep your vehicle in good working
condition. But we don’t know exactly
how you’ll 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 malting
deliveries. Or you may drive it to work,
to do errands
or in many other ways.
Because of all the different ways people
use their GM vehicles, maintenance
needs vary. You may even need more
frequent checks and replacements than
you will find in the schedules in this
part.
So please read this part and note
how you drive. If you have any
questions on how to keep your vehicle
in good condition, see your Chevrolet
dealer, the place many
GM owners
choose to have their maintenance work
done. Your dealer can be relied upon to
use proper parts and practices.
204
Your Vehicle and the Environment
Proper vehicle maintenance not only
helps to keep your vehicle in good
working condition, but also helps the
environment. All recommended
maintenance procedures are important.
Improper vehicle maintenance or the
removal of important components can
significantly affect the quality of the air
we breathe. Improper fluid levels or
even the wrong tire inflation can
increase the level
of emissions from
your vehicle.
To help protect our
environment, and to help keep your
vehicle in good condition, please
maintain your vehicle properly.
How This Part is Organized
The remainder of this part is divided
into five sections:
“Section A: Scheduled Maintenance
Services” shows 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’s
service department or another qualified
service center do these jobs. If
you are skilled enough to do some
work on your vehicle, you will probably
want to get the service information GM
publishes. You will find a list of
publications and how
to get them in
this manual. See
Service Publications
in the Index.
“Section B: Owner Checks and
Services” tells you what should be
checked whenever you stop for fuel. It
also explains what you can easily do to
help keep your vehicle in good
condition.
“Section
C: Periodic Maintenance
Inspections” explains important

Explanation of Scheduled
Maintenance Services
Following are explanations of the

whoever services your vehicle uses
these. All parts should be replaced and
all necessary repairs done before you or
anyone else drives the vehicle.
ITEM SERVICE
NO.
1. Engine Oil and Filter Change* -
Always use SH or SG Energy
Conserving I1 oils of proper viscosity.
The
“SH” or “SG” designation may
be shown alone or in combination
with others, such as “SH/CD,”
“SH,
SG, CD,” “SG/CD,” etc. To
determine the preferred viscosity for
your vehicle’s engine (e.g., SAE 5W-
30 or SAE 10W-30), see
Engine Oil
in the Index.
the suspension and steering linkage.
Lubricate the transaxle shift linkage.
Inspection - For proper wear and
maximum tire life, rotate your tires
following the instructions in this
manual. See
Tires, Inspection G
Rotation in the Index. Check the
tires for uneven wear or damage. If
you see irregular or premature wear,
check the wheel alignment. Check for
damaged wheels also.

flush and refill the system with new
or approved recycled coolant
conforming to
GM Specification
1825M. Keep coolant at the proper
mixture as specified. See
Coolant in

inhibitor level and maintains proper
engine operating temperature.
Inspect hoses and replace if they are
cracked, swollen or deteriorated.
Tighten screw-type hose clamps.
Clean the outside of the radiator and
air conditioning condenser. Wash the
pressure cap and neck.
To help ensure proper operation, we
recommend a pressure test
of both the
cooling system and the pressure cap.

General Motors, however, urges that all
recommended maintenance services be
performed at the indicated intervals and the
maintenance be recorded in “Section
E:
