1996 CHEVROLET TAHOE maintenance

Downloaded from www.Manualslib.com manuals search engine When to Check
Check your tires once a month or more. Also, check the
tire pressure of the spare tire.
How to Check
Use a good quality pocket-type gage to check tire
pressure.
You can’t tell.if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.
Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles
(10
000 to 13 000 km) for any signs of unusual wear.
If unusual wear is present, 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.
I FRT FRT
The purpose of regular rotation is to achieve more
uniform 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 one
of the correct
rotation patterns shown here.

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.
Finish Damage
Any stone chips, fractures or deep scratches in the finish
should be repaired right away. Bare metal will corrode
quickly and may develop into a major repair expense.
Minor chips and scratches can be repaired with touch-up
materials available from your dealer or other service
outlets, Larger areas of finish damage can
be corrected
in your dealer’s body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and dust control
can collect on the underbody.
If these are not removed,
accelerated corrosion (rust)
can occur on the underbody
parts such as
fuel lines, frame, floor pan and exhaust
system even though they have corrosion .protection. At least every spring, flush these materials from the
underbody with plain water. Clean any areas where mud
and other debris can collect. Dirt packed in closed areas
of the frame should be loosened before being flushed.
Your dealer or an underb.ody vehicle washing system
can do this for you.
.<
Chemical Paint Spotting
Some weather and atmospheric conditions can create
a chemical fallout. Airborne pollutants can fall upon
and attack painted surfaces on your vehicle. This
damage can take two forms: blotchy, ringlet-shaped
’
discolorations, and small irregular dark spots etched into
the paint surface.
Although no defect in the paint job causes this,
GM
will repair, at no charge to the owner, the surfaces of
new vehicles damaged by this fallout condition within
12 months or 12,000 miles
(20 000 km) of purchase,
whichever occurs first.

safety, dependability and emission control performance.

Introduction
Your Vehicle and the Environment
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.

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 GM
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 dealer.
This part tells you the maintenance services you should
have done and when
you should schedule them. If you
go to your dealer 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:

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:
Gasoline engine vehicles and diesel engine vehicles
have different maintenance requirements.
If you have a
diesel engine, follow a schedule designated for diesel
engine vehicles only.

maintenance schedules.
