Rear Axle What to Use
When to Check and Change Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant and when to change it. See
“Scheduled Maintenance Services”
in the Index.
How to Check Lubricant
If the level is below the bottom of the filler plug hole,
you’ll need to add some lubricant. Add enough lubricant
to raise the level to the bottom of the filler pl~~g hole. Refer
to the Maintenance Schedule to determine what
kind of lubricant to use. See “Recommended
Fluids and
Lubricants”
in the Index.
Engine Coolant
The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant is designed
to remain
in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs first, if you add only
DEX-COOL@ extended life coolant.
J
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.
A 50/50 mixture of water and DEX-COOL@
coolant will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.

Brakes
Brake Fluid
of the brake system. If it is, you should have yo~~r brake
system tlxed, since
a leak nleans that sooner or later your
brakes won't work well, or won't work at
all.
So. it isn't a good idea to "top oft'' your brake fluid.
Adding brake fluid won't correct
a leak. If you add fluid
when your linings are worn, then you'll have too much
fluid when you get new brake linings. You should add
(or remove) brake fluid, as necessary, only when work is
done on the brake hydraulic system.
Your brake master cylinder reservoir is here.
It is filled
with DOT-3 brake fluid.
There are only two reasons
why the brake fluid level in the
reservoir might go down. The first is that the brake fluid
goes down to an acceptable level during norlnal brake
lining weal-. When new linings are
put in, the fluid level
goes back up. The other reason is that fluid is leaking out
If you have too much brake fluid, it can spill on
the engine. The fluid
will burn if the engine is
hot enough. You or others could be burned,
and your vehicle could be damaged. Add brake
fluid only when work
is done on the brake
hydraulic system.
Refer to the Maintenance Schedule to determine when to
check your brake fluid. See "Periodic Maintenance
Inspections"
in the Index.

Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to I3 000 km). Any time you notice unusual
wear, rotate your tires as
soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See “When
It’s Time for New Tires” and
“Wheel Replacement” later
in this section for
more information.
The purpose of regular rotation is to achieve more
lrniform wear for all tires on the vehicle. The first
rotation is the most important. See ”Scheduled
Maintenance Services”
in the Index for scheduled
rotation intervals. When rotating your
tires, always use the correct rotation
pattern shown here.
If your vehicle has a compact spare tire, don’t include it
in your tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown
on the
CertificatiodTire label. Make certain that all wheel nuts
are properly tightened. See “Wheel
Nut Torque’‘ in
the Index.
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose
after a time. The wheel could 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 a 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 the Index.)

Your Vehicle and the EnvironmcC
Proper vehicle maintenance not only helps to keep your
vehicle
in good working condition, but also helps the
environment.
All recommended maintenance procedures
are important. Improper vehicle maintenance can even
affect the quality of the air we breathe. Improper fluid
levels or the wrong tire inflation can increase
the level
of emissions from your vehicle. To help protect our
environment. and to keep your vehicle
in good
condition, please maintain your vehicle properly.
How This Section is Organized
The remainder of this section is divided into five parts:
“Part A: Scheduled Maintenance Services” shows
what to have done and how often. Some
of these
services can be complex,
so unless you are technically
qualified
and have the necessary equipment, you should
let your retailer’s service department or another
qualified service center do these
jobs.

Part A: Scheduled Maintenance
Services
Using Your Maintenance Schedule
We at General Motors want to help you keep your vehicle
in good working condition. But we don‘t know exactly
how you’ll drive
it. You may drive very short distances
only a few times
a week. Or you may drive long distances
all
the time in very hot, dusty weather. You may use your
vehicle
in making deliveries. Or you may drive it to work,
to do en-ands or
in many other ways.
Because of
all the different ways people use their
vehicles, maintenance needs vary. You may even need
more frequent checks and replacements than
you’ll find
in the schedules in this section. So please read this
section and note how you drive.
If you have any
questions on how to keep your vehicle
in good
condition, see your
GM retailer.
This part tells you the maintenance services you should
have done and
when you should schedule them. If you
go to your retailer for your service needs, you’ll know
that GM-trained and supported service people
will
perform the work using genuine GM parts. The proper fluids and lubricants to use are listed
in
Part D. 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.
These schedules are for vehicles
that:
0 carry passengers and cargo within recommended
limits. You
will find these limits on your vehicle’s
Certification/Tire label. See “Loading Your Vehicle”
in the Index.
0 are driven on reasonable road surfaces within legal
driving limits.
0 use the recommended fuel. See ”Fuel” in the Index.
Selecting the Right Schedule
First you’ll need to decide which of the two schedules is
right for your vehicle. Here’s how to decide which
schedule to follow:
ProCarManuals.com

Maintenance Schedule
I Short Trip/City Definition
Follow the Short Trip/City Maintenance Schedule if any
one of these conditions is true for your vehicle:
0
0
0
0
0
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
You operate your vehicle in dusty areas or
off-road frequently.
You frequently tow a trailer or use a carrier on top of
your vehicle.
If
the vehicle is used for delivery service, police, taxi
or other commercial application.
One of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions cause engine oil to break
down sooney:
Short Trip/City Intervals
Every 3,000 Miles (5 000 km): Engine Oil and
Filter Change (or
3 months, whichever occurs first).
