Front Axle Engine Coolant
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
“Periodic Maintenance Inspections” and “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.
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. 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 Geo will:
0 Give freezing protection down to -33°F (-36°C).
Give boiling protection up to 258°F (125°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights work as they should.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half antifreeze that meets
“GM
Specification 1825M,” which won’t damage aluminum
parts. You can also use a recycled coolant conforming to
GM Specification 1825M with a complete coolant flush
and refill. If you use this mixture, you don’t need to add
anything else.

When the engine compartment is hot, the level
should
be at the MAX mark.
When the engine compartment is cool, the level
should be at the MIN mark.
A fluid loss in this system could indicate a problem.
Have the system inspected and repaired.
What to Add
Refer to the Maintenance Schedule to determine what
kind
of fluid to use. See “Recommended Fluids and
Lubricants” in the Index.
NOTICE:
When adding power steering fluid or making a
complete fluid change, always use the proper
fluid. Failure to use the proper fluid can cause
leaks and damage hoses and seals.

Brakes
Brake Master Cylinder
YOLK 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.

Inflation - Tire Pressure
The Tire-Loading Information label which is on the
driver’s door shows the correct inflation pressures for
your tires, when they’re cold.
“Cold” means your
vehicle has been sitting for at least three hours or driven
no more than
a mile.
I
’ NOTICE:
Don’t let anyone tell you that underidation or
~ overinflation is all right. It’s not. If your tires don’t
~ have enough air (underinflation) you can get:
Too much flexing
Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy.
If your tires have too much air (overinflation),
you can get:
Unusual wear
0 Bad handling
Rough ride
Needless damage from road hazards. 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. Simply looking at the tires will
not tell you the
pressure, especially if you have radial tires
-- which
may look properly inflated even
if they’re underinflated.
If your tires have valve caps, be sure to put them back on.
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.
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.

Gem Section 7 Maintenance Schedule
IMPORTANT:
KEEP ENGINE OIL
AT THE PROPER
RECOMMENDED
This section covers the maintenance required for your
Geo. Your vehicle needs these services to retain
its
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 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.
Have you purchased the GM Protection Plan .? The Plan
supplements your new vehicle warranties. See your
Chevrolet/Geo dealersfor details.

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.
“Part B: Owner Checks and Services” tells you what
should be checked whenever
you stop for fuel. It also
explains what
you can easily do to help keep your
vehicle in good condition.
“Part C: Periodic Maintenance Inspections” explains
important inspections that your Chevrolet/Geo dealer’s
service department or another qualified service center
should perform.
“Part D: Recommended Fluids and Lubricants” lists
some products
GM recommends to help keep your
vehicle properly maintained. These products, or their
equivalents, should be used whether you do the work
yourself
or have it done.
“Part E: 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 part. 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.
If you are skilled enough to do some work
on your
vehicle, you will probably want to get the service
information
GM publishes. See “Service Publications”
in the Index.

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 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’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 Chevrolet/Geo 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:
0 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.
use the recommended unleaded 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:
