Downloaded from www.Manualslib.com manuals search engine 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 making deliveries. Or you may drive it to work, to do errands, or in many
other ways.
Because of all the different ways’pWple use their GM vehicle\
s, maintenance
needs vary. You may even need more frequent checks and replacements than
you will find in the schedules in this section.
So please read this section and
note how you drive. If you have any questions on how to keep your vehicle
in good condition, see your GM dealer, the place many GM owners \
choose
to have their maintenance work done. Your dealer can be relied up\
on to use
proper parts and practices.
Your Vehicle And The Environment
Proper vehicle maintenance not only helps keep your vehicle in good
working condition, but it 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 infla\
tion 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.
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 Section
8, Customer Assistance
Information.
See “Service Publications” in the Index.
The Maintenance Record provides a place for you to record the maintenance
performed on your vehicle. Whenever any maintenance is performed\
, be
sure
to write it down in this section. This will help you determine when your
next maintenance should be done. In addition, it is a good idea to keep your

warranty repairs.
Scheduled Mainfenance Services
This part tells you the maintenance services you should have done and wh\
en
you should schedule them. Your GM dealer knows your vehicle best and
wants you to be happy with it. If you go to your dealer for all your service
needs, you’ll know that GM-trained and supported service peop\
le will
perform the work using genuine GM
parts.

Listed below are inspections and services which should be perfo\
rmed at
least twice a year (for instance, each spring and fall). You should let your
GM dealer’s service department or other qualified service center do these
jobs. Make sure any necessary repairs are completed
at once.
Steering and Suspension Inspection? - Inspect front and rear suspension

lack of lubrication. Inspect power steering lines and hoses for proper
hook-up, binding, leaks, cracks, chafing, etc.

Accelerator Control System - Lubricate all pivot points with engine oil,
except the
TBI throttle shaft. Do not lubricate the cam pulley. Remove all
external deposits from pulley.
Do not oil any accelerator or cruise control
cables. Replace any cables that have high effort or excessive \
wear.
Exhaust System Inspection - Inspect the complete system. Inspect the
body near the exhaust system. Look for broken, damaged, missing
or
out-of-position parts, as well as open seams, holes, loose conn\
ections or
other conditions which could cause a heat buildup in the
floor pan or could
let exhaust fumes seep into the passenger compartments. See “Engine
Exhaust” in the Index.
Drive Axle Service - Check readfront axle fluid level and add as needed.
Check constant velocity joints and axle seals for leaking.
Transfer Case (four-wheel drive) Inspection? - Every 12 months or at
oil change intervals, check front axle and transfer case and add l\
ubricant
when necessary. Check vent hose at transfer case
for kinks and proper
installation. More frequent lubrication may be required on off-road use.

and repaired at once.

Downloaded from www.Manualslib.com manuals search engine Bulletins cover various subjects. Some pertain to the proper us\
e and care of
your vehicle. Some describe costly repairs, Others describe inex\
pensive
repairs which, if done on time with the latest parts, may avo\
id future costly
repairs. Some bulletins tell
a technician how to repair a new or unexpected
condition. Others describe
a quicker way to fix your vehicle. They can help
a technician service your vehicle better.
Most bulletins apply to conditions affecting a small number of cars or
trucks. Your Chevrolet dealer or a qualified technician may have to
determine if a specific bulletin applies to your vehicle.
You
can subscribe to all Chevrolet’s bulletins by calling Helm, Inc. at
1-800-782-4356. This way you’ll get them
as they become available.
mdividual PSP’s
li you don’t want to buy all the PSP’s issued by Chevrolet \
for au car67
truck models in the model year, you can buy individual PSP’s, such as those\

which may pertain to a particular model. To do this, you will first need to
see our index of PSP’s. It provides a variety of information. Here’s what
you’ll find in the index and how you can get one:
What You’ll Find in the Index:
A list of PSP’s published by Chevrolet in a model year (1990 or later).
PSP’s covering all models of Chevrolet cars or light trucks (less than
10,000 pounds (4
536 kg) GVWR) are listed in the same index.
Ordering information so you can buy the specific PSP’s you may want.
Price information for the PSP’s you may want to buy.
How You Can Get an Index:
Indexes are published periodically. Most of the PSP’s which could
potentially apply to the most recent Chevrolet models will be \
listed in the
most recent publication for that model year. This means you may want to
wait until the end
of the model year before ordering an index, if you are
interested in buying PSP’s pertaining to a current model year car or truck.
Some PSP’s pertaining to a particular model year vehicle may\
be published
in later years, and these would be listed
in the later year’s index. When you
order an index for a model year that is not over yet, we’ll send you the mos\
t
recently published~issue. Check the ordering form for indexes for earlier
model years.
Cut out the ordering form, fill it out, and mail it in. We will then see to it
that an index is mailed to you. There
is no charge for indexes for the
1989-1994 model years.
