Use this rotation pattern. Do not include “compact spare tire” in rotation, if so
equipped.
If your vehicle has front tires with different load ratings or tr\
ead designs (such
as all season vs. on/off road) than the rear tires, don’t \
rotate your tires front
to rear.
If you have styled steel or aluminum wheels, your spare is full-s\
ized, but its
appearance will not match your other wheels.
After the tires have been rotated, adjust the front and rear \
inflation pressure as shown on the CertificationRire label. Make certain that
all wheel nuts are
properly tightened. See “Wheel Nut Torque” in the Index.
A
Rust or dirt on a wheel, or on the parts to which it is fastened, can
make the wheel nuts become loose after a time. The wheel coul\
d
come off and cause an accident. When you change a wheel, remove
any rust or dirt from places where the wheel attaches to the \
vehicle.
In an emergency, you can use a cloth or paper towel to
do this; but
be sure to use a scraper or wire brush later, if you need to, to get
all the rust or dirt off. (See “Changing a Flat Tire” in t\
he Index.)

don’t have a spare fuse, you can “borrow” one of the correct value. Just pick
some feature of your vehicle that you can get along without-like the radio or
cigarette lighter-and use its fuse,
if it is of the value you need. Replace it
as soon as you can. See “Fuses and Circuit Breakers” in this section.

intervals. Ask your dealer for the proper replacement intervals for your
driving conditions.
6. FRONT WHEEL BEARING REP1 -;< (2-WHEEL DRIVE ONLY) -Clean
and repack the front wheel bearings at each brake relining, or at the
specified interval, whichever comes first.
7. TRANSMISSION SERVICE:
Automatic Transmission -Change the transmission fluid and filter \
every 15,000 miles (25
000 km) if the vehicle is mainly driven under one or
more of these conditions:
In heavy city traffic.
Where the outside temperature regularly reaches 90°F (32°C) or

urns, cracks or other damage. Check the wire boot fit at the distributor and \
at
the spark plugs. Replace wires as needed.
11. ENGINE TIMING CHECK AND DISTRIBUTOR CHECK* -Adjust timing to underhood label specifications. Inspect the inside and outsid\
e of the
distributor cap and rotor for cracks, carbon tracking and corro\
sion. Clean or replace as needed.

13. ENGINE ACCESSORY DRIVE BELT INSPECTION*-Inspect belt. Look
for cracks, fraying, wear, and proper tension. Adjust or replac\
e as needed.
14. 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
II and then every 15,000 miles (25 000 kilometers) thereafter.
Follow the instructions and patterns shown in Section
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.
15. DRIVE AXLE SERVICE -Check rear/front axle fluid level and add \
as
needed. Check constant velocity joints and axle seals for leaki\
ng.
Locking differential -Drain fluid at first oil change and refill. Check
fluid level and add as needed at subsequent oil changes. In d\
usty areas
or trailer towing applications, drain fluid at every 15,000 miles
(24
135 kilometers) and refi1l.t
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 refil1.t
More frequent lubrication may be required for off-road use.
16. 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.t
When the wheels are removed for rotation, inspect disc brake p\
ads 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.
tA fluid
loss in these systems may indicate a problem. Have them inspected
and repaired at once.

Downloaded from www.Manualslib.com manuals search engine 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 lnspectiont -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. (On vehicles equipped with manual
steering gear, check for seal leakage.) 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 connections 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 rear/front axle fluid level and add as needed.
Check constant velocity joints and axle seals for leaking.
Transfer Case (four-wheel drive) lnspectiont -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 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.
tA fluid loss in these systems may indicate a problem. Have them inspected
and repaired at once.
