Most lubricant checks in this section also apply to

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.
A 50/50 mixture of water and the proper coolant will:
0 Give freezing protection down to -33°F (-36°C).
Give boiling protection up to 258 OF (1 25 O C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half coolant that meets GM
Specification 1825-M, which won’t damage aluminum
parts.
You can also use a recycled coolant conforming
to GM Specification 1825-M with a complete coolant
flush and refill.
If you use this mixture, you don’t need
to add anything else.
Adding only plain water
to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mixture will. Your vehicle’s coolant
warning system
is set for the proper coolant
mixture. With plain water or the wrong mixture,
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 a
50/50 mixture of clean water and the
proper coolant.

Downloaded from www.Manualslib.com manuals search engine If it is, you should have your brake system fixed, since a Checking Brake Fluid
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.
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.
You can check the brake
fluid without taking
off
the cap.
Just look at the brake
fluid reservoir. The fluid level should be above MIN.
If it isn’t, have your brake
system checked to see
if
there is a leak.
After work is done
on the brake hydraulic system,
make sure the level is above the MIN but not over
the
MAX mark or the top of the window on the side
of the reservoir.

Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 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 “Whe\
el
Replacement” later in this section for more information.
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.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire-Loading
Information label. Make certain that
all wheel nuts
are properly tightened. See “Wheel Nut Torque” in
the Index.

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.
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 dealer’s service department or another qualified
service center do these jobs.

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 errands 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 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:
carry passengers and cargo within recommended
limits. You will find these limits on your vehicle’s
Tire-Loading Information label. See “Loading Your
Vehicle” in the Index.
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:
