Brake Master Cylinder
Your brake master
cylinder is here. It is
filled with
DOT-3
brake fluid.
There are
only two reasons why the brake fluid level in your master cylinder
might go down. The first is that the brake fluid goes down to an acceptable
level during normal brake lining wear. When new linings are put in,
the
fluid level goes back up. The other reason is that fluid is leaking out of the
brake system.
If it is, you should have your brake system fixed, since a leak
means 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 off’ 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.
Refer to the Maintenance Schedule to determine when
to check your brake
fluid. See “Periodic Maintenance Inspections”
in the Index.

Front Suspension and Steering Linkage
Refer to the Maintenance Schedule to determine how often to lubricate the
fittings and what type of lubricant to use.
Front Wheel Bearing (Two- Wheel Drive)
If your vehicle is two-wheel drive, it has wheel bearings that must be
cleaned and repacked.
Refer to the Maintenance Schedule to determine how often this must be
done.
Single Belt Accessory Drive
Your new vehicle uses a serpentine belt that is lighter, and more durable
than systems with several belts.
The belt runs over or around the pulleys on the engine. A tensioner is used
to keep the belt tight at all times. 'The tensioner also makes replacing the
belt easier. If you need to replace the belt, be sure to get the correct
replacement belt. Your dealership or parts supplier can help you with this.
The Accessory Drive Belt Routing label on your vehicle will show you how
to route the belt your vehicle uses.

To replace your
windshield wiper
blade inserts, lift the
wiper
arm away from
the windshield. Pinch
the two tabs on the
wiper arm and slide
the insert out of the
blade. Slide the new

system to be sure it has not lost any cooling ability.
If you think the system
is not working properly, have your dealership check it out as soon as
possible.
The air conditioning will not work when the temperature is below
40°F
(4°C).
Lubrication
Accelerator Control System
Refer to the Maintenance Schedule to determine how often the accelerator
linkage pivot points must be lubricated and what type of lubricant to use.
Accelerator cables and cruise control cables should not be lubricated. Any
cables that
are worn or are hard to pull should be replaced.
When cleaning the engine compartment with water or steam, avoid directing
the flow onto the throttle linkage in a manner that would cause moisture to
enter the cables.
Hood Latches and Hood Hinge
Refer to the Maintenance Schedule to determine how to lubricate the hood
latch and hood hinge assembly.

Downloaded from www.Manualslib.com manuals search engine Propeller Shaft Slip Splines/Universal Joints
Refer to the Maintenance Schedule to determine how often the slip and
universal joints must be lubricated and what type of lubricant to use.
Body
Normal use of your vehicle will cause metal to metal wear at some points on
the cab and body if they are not lubricated.
For exposed surfaces, such as door checks, door lock bolts, lock s\
triker plates,
dovetail bumper wedges, etc., a
thin film of engine oil should be applied.
Where oil holes are provided
in the body or cab, a dripless oil can be used.
The seat adjusters and seat track should be lubricated with chassis grease.
Door weatherstrips and rubber hood bumpers should be wiped clean with a
wet cloth and lightly coated with a rubber lubricant.
Never use too much of any lubricant and be sure to wipe up any extra
lubricant when
you are finished.
Window regulators and controls are inside the doors. They are lubricated
with a long lasting grease.
If lubrication is required your dealer should
perform this service.
Refer to the Maintenance Schedule to determine how often to lubricate
these items and what type of lubricant to use.
Lock Cylinders
To be sure your locks operate properly, they must be lubricated.
Refer to the Maintenance Schedule to determine how often
to lubricate them
and what type of lubricant to
use.
You should not use penetrating oils because they could wash out the factory
installed lubricant and cause
the lock to bind. De-icers which contain
alcohol could also wash away the lubricant,
so be sure to lubricate the lock
after using a de-icer of this type.
Endgate Handle
The endgate handle pivot points on your vehicle should be lubricated to
keep the handle working smoothly.
Refer to the Maintenance Schedule
to determine how often to lubricate them
and what type of lubricant to use.

Downloaded from www.Manualslib.com manuals search engine A Word About Maintenance
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 errands, or in many
other ways.
Because of all the different ways people use their GM vehicles, maintenance
needs vary. You may even need more frequent checks and replacements than
you will 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 dealer, the place many GM owners choose
to have their maintenance work done. Your dealer can be relied upon
to use
proper parts and practices.
Your Vehicle And The Environment
Proper vehicle maintenance not only helps keep your vehicle in good
working condition, but it also helps the environment. All recommended
maintenance procedures are important. Improper vehicle maintenance or the
removal of important components can significantly affect the quality of the
air
we breathe. Improper fluid levels or even the wrong tire inflation can
increase the level of emissions from your vehicle. To help protect our
environment, and to help keep your vehicle in good condition, please
maintain your vehicle properly.
If you are skilled enough to do some work on your vehicle, you will
probably want to get the service information GM publishes. You will find a
list of publications and how to get them in Section
8, Customer Assistance
Information.
See “Service Publications” in the Index.
The Maintenance Record provides a place for you
to record the maintenance
performed on your vehicle. Whenever any maintenance is performed, be
sure to write it down in this section. This will help you determine when your
next maintenance should be done. In addition, it is a
good idea to keep your
maintenance receipts. They may be needed to qualify your vehicle for
warranty repairs.
