Part B: Owner Checks and Services
Listed below are owner checks and services which should be performed at
the intervals specified to help ensure the safety, dependability and emission
control performance
of your vehicle.
Be sure any necessary repairs are completed at once. Whenever any fluids
or lubricants are added
to your vehicle, make sure they are the proper ones,
as shown in Part
D.
At Each Fuel Fill
It is important for you or u service station attendant to perjorm these
underhood checks at each fuel
fill.
Engine Oil Level
Check the engine oil level and add the proper oil if necessary. See “Engine
Oil” in the Index for further details.
Engine Coolant Level
Check the engine coolant level and add the proper coolant mix if necessary.
See “Coolant”
in the Index for further details.
Windshield Washer Fluid Level
Check the windshield washer fluid level in the windshield washer tank and
add the proper fluid
if necessary. See “Windshield Washer Fluid” in the
Index for further details.
At Least Once a Month
lire Inflation
Check tire inflation. Make sure tires are inflated to the pressures specified
on the Certificationire label which is located on the rear edge
of the
driver’s door or
on the incomplete vehicle document in the cab. See “Tires”
in the Index for further details.
Cassette Deck
Clean cassette deck. Cleaning should be done every 50 hours of tape play.
See “Audio Systems” in the Index for further details.

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.
