Part C: Periodic Maintenance Inspections
Listed below are inspections and services which should be performed 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 lnspection
Inspect the front and rear suspension and steering system for damaged,
loose or missing parts, signs
of wear, or lack of lubrication. Inspect power
steering lines and hoses for proper hookup, binding, leaks, cracks, chafing,
etc. (On vehicles equipped with manual steering gear, check
for seal
leakage.)
Exhaust System lnspection
Inspect the complete exhaust 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 connections, or other conditions which could
cause
a heat build-up in the floor pan or could let exhaust fumes into the
vehicle.
See “Engine Exhaust’’ in the Index.
Accelerator Control System
On gasoline engines, lubricate the pivot at the TBI throttle lever stud with
engine oil.
Do not oil any accelerator or cruise control cables. Replace any
cables that have high effort or excessive wear.
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 lubricant when necessary. Oil the control lever pivot point and
all exposed control linkage. Check vent hose
at transfer case for kinks and
proper installation. More frequent lubrication
may be required on off-road
use.

Part E: Maintenance Record
After the scheduled services are performed, record the date, odometer
reading and who performed
the service in the boxes provided after the
maintenance interval. Any additional information from “Owner Checks and
Services” or “Periodic Maintenance” can be added
on the following record
pages. Also,
you should retain all maintenance receipts. Your owner
information portfolio is a convenient place to store them.

Service and Owner Publications
Service manuals, service bulletins, owner’s manuals and other service
literature are available for purchase for all current and many past model
General Motors vehicles.

Service Manuals
Service manuals contain diagnosis and repair information for all chassis and
body systems. They may be useful for owners who wish
to get a greater
understanding of their vehicle. They are also useful for owners with the
appropriate skill level or training who wish to perform “do-it-yourself’
service. These are authentic General Motors’ service manuals meant for
professional, qualified technicians.
Service Bulletins
Service bulletins covering various subjects are regularly sent to all General
Motors dealerships. GM monitors product performance in the field. When
service methods are found which promote better service on GM vehicles,
bulletins
are created to help the technician perform better service. Service
bulletins may involve any number of vehicles. Some will describe
inexpensive service; others will describe expensive service. Some will
advise
of new or unexpected conditions, and others may help avoid future
costly repairs. Service bulletins are meant for qualified technicians. In some
cases they refer to service manuals, specialized tools, equipment and safety
procedures necessary to service the vehicle. Since these bulletins are issued
throughout the model year and beyond, an index is required and published
quarterly
to help identify specific bulletins. Subscriptions are available. You
can order an index at the toll-free numbers listed previously, or ask a GM
dealer to see an index or individual bulletin.
Owner Publications
Owner’s manuals, warranty folders and various owner assistance booklets
provide owners with general operation and maintenance information.
