Downloaded from www.Manualslib.com manuals search engine Protecting Exterior Bright Metal Parts
Bright metal parts should be cleaned regularly to keep their luster. Washing
with water is all that is usually needed. However, you may use
GM Chrome
Polish on chrome or stainless steel trim, if necessary.
Use special care
with aluminum trim. To avoid damaging protective trim,
never use auto or chrome polish, steam or caustic soap to clean aluminum.
A coating of wax, rubbed to high polish, is recommended for all bright
metal parts.
Aluminum Wheels (If So Equipped)
Your aluminum wheels have a protective coating similar to the painted
surface
of your vehicle. Don’t use strong soaps, chemicals, chrome polish,
abrasive cleaners or abrasive cleaning brushes on them because you could
damage this coating. After rinsing thoroughly, a wax may be applied.
NOTICE:
If you have aluminum wheels, don’t use an automatic vehicle
wash that has hard silicon carbide cleaning brushes. These
brushes can take
off the protective coating.
Weatherstrips
Silicone grease on weatherstrips will make them last longer, seal better, and
not stick or squeak. Apply silicone grease
with a clean cloth at least every
six months. During very cold, damp weather more frequent application may
be required. (See “Recommended Fluids
& Lubricants” in the Index.)
Sheet Metal Damage
If your vehicle is damaged and requires sheet metal repair or replacement,
make sure the body repair shop applies anti-corrosion material to
the parts
repaired or replaced to restore corrosion protection.
Foreign Material
Calcium chloride and other salts, ice melting agents, road oil and tar, tree
sap, bird droppings, chemicals from industrial chimneys, and other foreign
matter can damage your vehicle’s finish
if they remain on painted surfaces.
Use cleaners
that are marked safe for painted surfaces to remove foreign
matter.

Not all air conditioning refrigerants are the same. If the air conditioning
system in your vehicle needs refrigerant, be sure the proper refrigerant is
used. If you’re not sure, ask your
GM dealer. For additional information, see

Downloaded from www.Manualslib.com manuals search engine Explanation Of Scheduled Maintenance Services
Below are explanations of the services listed in the maintenance charts.
The proper fluids and lubricants to use are listed
in this section. 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.

ENGINE OIL AND OIL FILTER CHANGE“ - ALWAYS USE
API SERVICE
SH OR SG ENERGY CONSERVING I1 OILS OF THE
PROPER VISCOSITY. The
“SH7 or “SG7 designation may be shown
alone or in combination with others, such as “SWCD”, or
“SH, SG,
CD,” or “SG/CD”, etc. To determine the preferred viscosity oil for your
vehicle’s engine see “Engine Oil”
in the Index.
CHASSIS LUBRICATION - Lubricate the front suspension,
steering linkage, transfer case shift linkage, parking brake cab\
le guides,
and brake pedal springs at the intervals specified on the proper
maintenance schedule, or at every engine oil change, whichever \
comes
first.
Ball joints and king pin bushings should not be lubricated unless their
temperature is
10°F (-1 2°C) or higher. When the weather is cold, let
them warm up before lubricating them or they could be damaged.\

Also, be sure to check all the vehicle fluid levels at this \
time.
COOLING SYSTEM SERVICE* - Drain, flush and refill the
system
with new or approved recycled coolant conforming to “GM
Specification 6038-M”. See “Engine Coolant”
in the Index for the
proper coolant and mixture to use
in your vehicle.
Also inspect the hoses and replace them
if they are cracked, swollen, or
deteriorated. Clean the outside of the radiator and air conditioning
condenser. Wash the radiator neck.
To ensure proper operation,
pressure test the radiator and cap.
AIR CLEANER FILTER REPLACEMENT* - Replace at
specified intervals. Ask your dealer for the proper replacement
intervals for your driving conditions.
FRONT WHEEL BEARING REPACK
(2-WHEEL DRIVE ONLY)
- Clean and repack the front wheel
bearings at each brake relining,
or at the specified interval, whichever
comes first.

Downloaded from www.Manualslib.com manuals search engine 13. TIRE AND WHEEL ROTATION AND INSPECTION - For
proper wear and maximum tire life, rotate tires at the first
6,000 miles
(10
000 kilometers) for Schedule I or 7,500 miles (12 500 kilometers)
for Schedule I1 and
then every 15,000 miles (25 000 kilometers)
thereafter. Follow the instructions and patterns shown in Sectio\
n
6.
Check tires for uneven wear or damage. If irregular or premature wear
is apparent, check wheel alignment. Also, check for damaged wheels.
See “Tires” in the Index for more information.
14.
DRIVE AXLE SERVICE - Check readfront axle fluid level and add
as needed. Check constant velocity joints and axle seals for leaking.
Locking Differential - Drain fluid at first oil change and refill.
Check fluid level and add as needed at subsequent oil changes. In
dusty areas or trailer towing applications, drain fluid at every
15,000 miles (24 135 kilometers) and refill.?
Standard Differential - Check fluid level and add as needed at
every oil change. In dusty areas or trailer towing applications\
,
drain fluid every
15,000 miles (24 135 kilometers) and refill.?
15. BRAKE SYSTEM INSPECTION - When the engine oil is changed,
inspect the lines and hoses for proper hookup, binding, leaks, cracks,
chafing, etc. Check the parking brake adjustment, and the fluid\
level in the master cylinder. A low fluid level can indicate
worn disc brake pads
which may need to be serviced.?
When the wheels are removed for rotation, inspect disc brake pads for
wear and rotors for surface condition. Also inspect drum brake linings
for wear and cracks. Inspect other brake parts, including drums, wh\
eel
cylinders, parking brake, etc. at the same time.
Inspect brakes more often if driving habits or conditions resul\
t in
frequent braking.
-f A fluid loss in these systems may indicate a problem. Have them inspected a\
nd
repaired at once.

Downloaded from www.Manualslib.com manuals search engine Periodic Maintenance Inspections
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
and steering system for damaged, loose or missing parts, signs of wear or
lack of lubrication. Inspect power steering lines and hoses for proper
hook-up, binding, leaks, cracks, chafing, etc. Lubricate the steering linkage.
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 (all-wheel drive) Inspection? - Every 12 months or at oil
change intervals, check front axle and transfer case and add l\
ubricant when
necessary. Oil the control lever pivot point (except
L Van) and all exposed
control linkage. Check vent hose at transfer case for kinks and proper
installation.
-F A fluid loss in these systems may indicate a problem. Have them inspected a\
nd
repaired
at once.
