If the level is below the bottom of the filler plug hole, you’ll need to add
some lubricant.
If the differential is at operating temperature (warm), add enough lubricant to
raise the level
to the bottom of the filler plug hole.
If the differential is cold, add enough lubricant to raise the level to 1/2 inch
(12 mm) below the filler plug hole.
What to Use:
Refer to the Maintenance Schedule to determine what kind of lubricant to
use. See “Recommended Fluids and Lubricants” in the Index.\
Engine Coolant
The following explains your cooling system and how to add coolant when it is
low.
If you have a problem with engine overheating, see “Engine
Overheating’’ in the Index.
The proper coolant
for your vehicle will:
Give freezing protection down to -20°F (-29°C) or -34°F (-37°C) for
Give boiling protection up to 258°F (125°C).
Canadian vehicles and vehicles with the cold climate option.
Protect against rust and corrosion.
Help keep
the proper engine temperature.
Let the warning lights and gages work as they should.

Service & Appearance Care
What to Use:
Use a mixture of clean water (preferably distilled) and antifreeze that meets
“GM Specification 6038-M,” which won’t damage aluminum parts. Also use
GM Engine Coolant Supplement (sealer) with
a complete coolant change. If
you use these, you don’t need to add anything else.
I
Adding only plain water to your cooling system can be dangerous.
proper coolant mix will. Your vehicle’s coolant warning system is set
for the proper coolant mix. With plain water or the wrong mix, your
engine could get
too hot but you wouldn’t get the overheat warning.
Your engine could catch fire and you or others could be burned. Use
- Plain water, or some other liquid like alcohol, can boil before the
II a 50/50 mix of clean water and a proper antifreeze.
NOTICE
J use an improper coolant mix, your engine could overheat and be
badly damaged. The repair cost wouldn’t be covered by your warrant\
y
much water
in the mix can freeze and crack the engine, radiator, hea
core and other
part
Some conditions, such as air trapped in the cooling system, can affect the
coolant level in the radiator. Check the coolant level when th\
e engine is cold
and follow the steps under “Adding Coolant” for the prope\
r way to add
coolant.
If you have to add coolant more than four times a year, have your dealer
check your cooling system.
’‘ you use the proper coolant, you don’t have to add extra inhibitors c-
auditives which claim to improve the system. These can be harmful. ~ ~~~~~

Service & Appearance Care
To Check Brake Fluid:
You can check the brake fluid without taking off the cap. Just look at the
windows on the brake fluid reservoir. The fluid levels should be above
MIN. If
they aren’t, have your brake system checked to see if there is a leak.
After work is done on the brake hydraulic system, make sure t\
he levels are above
MIN and below the top of each window.
What To Add
When you do need brake fluid, use only DOT-3 brake fluid-such as Delco
Supreme
11 @ (GM Part No. 1052535). Use new brake fluid from a sealed
container only.
Replacing Brake System Parts
The braking system on a modern vehicle is complex. Its many parts have to
be of top quality and work well together if the vehicle is to have really good
braking. Vehicles we design and test have top-quality GM brake parts in
them, as your vehicle does when
it is new. When you replace parts of your
braking system-for example, when your brake linings wear down and you
have to have new ones put in-be sure you get new genuine GM
replacement parts.
If you don’t, your brakes may no longer work properly. For
example,
if someone puts in brake linings that are wrong for your vehicle, the
balance between your front and rear brakes can change, for the\
worse. The braking performance you’ve come
to expect can change in many other ways
if someone puts in the wrong replacement brake parts.
Fluid Leak Check
After the vehicle has been parked for a while, inspect the su\
rface under the
vehicle for water, oil, fuel or other fluids. Water dripping from the air
conditioning system after
it has been used is normal. If you notice fuel leaks
or fumes, the causes should be found and corrected at once.

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 se\
ction. Make sure whoever services your vehicle uses these. All parts should be \
replaced and all necessary repairs done before you or anyone else drives th\
e vehicle.
1. ENGINE OIL AND OIL FILTER CHANGE* -ALWAYS USE SG OR SG/CE QUALITY, ENERGY CONSERVING
II OILS OF THE PROPER
VISCOSITY. To determine the preferred viscosity oil for your vehicle’s
engine (e.g. SAE 5W-30). See “Engine Oil” in the Index.\
2. CHASSIS LUBRICATION -Lubricate the front suspension, ball joint,
steering linkage, clutch, and transfer case shift linkage, parki\
ng brake
cable guides, propshaft splines, universal joints, brake pedal s\
prings, and
clutch pedal springs at the intervals specified on the proper \
maintenance
schedule, or at every engine oil change, whichever comes first.\
On
vehicles without hydraulic clutches, lubricate the clutch cross \
shaft every
30,000 miles
(50 000 km).
Ball joints should not be lubricated unless their temperature i\
s 10°F
(-12°C) or higher. When the weather is cold, let them war\
m up before
lubricating them or they could be damaged.
Also, be sure to check all the vehicle fluid levels at this \
time.
3. CLUTCH FORK BALL STUD LUBRICATION (4.3L ENGINES ONLY)
-Lubricate the clutch fork ball stud through the fitting on th\
e clutch housing. Lubricant must be added “sparingly” to the fittin\
g, as only
.0066
Ib. (.003 kg) is required to lubricate the ball stud surface\
. Do not add
lubricant more often than the intervals recommended in the Main\
tenance
Schedules. Too much lubricant
will damage the clutch assembly.
4. COOLING SYSTEM SERVICE* -Drain, flush and refill the system wit\
h
new coolant. See “Engine Coolant’’ in the Index for th\
e proper coolant
and mixture to use in your vehicle.
Also inspect the hoses and replace them
if they are cracked, swollen, or
deteriorated. Tighten all hose clamps. Clean the outside of the radiator
and air conditioning condenser. Wash the radiator neck. To ensure proper
operation, pressure test the radiator and cap.

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.
