Automatic Transmission Fluid
When to Check and Change
A good time to check your automatic transmission fluid
level is when the engine oil is changed. Refer to the
Maintenance Schedule to determine
when to change
your fluid. See “Scheduled Maintenance Services”
in the
Index.
How to Check
Because this operation can be a little difficult, you may
choose to have this done at your Chevrolet/Geo dealer
Service Department.
If you do it yourself, be sure to follow all the
instructions here, or you could get a false reading on the
dipstick.
NOTICE:
Too much or too little fluid can damage your
transmission.
Too much can mean that some of
the fluid could come out and fall on hot engine
parts or exhaust system parts, starting a fire. Be sure to get an accurate reading if you check your
transmission fluid.
Wait at least 30 minutes before checking the
transmission fluid level if you have been driving:
0 When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
0 In heavy traffic -- especially in hot weather.
0 While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which is
180” F to 200” F
(82°C to 93°C).

How to Add Fluid Manual Transmission Fluid
Refer to the Maintenance Schedule to determine what
kind
of transmission fluid to use. See “Recommended
Fluids and Lubricants” in the Index.
Add fluid only after checking the transmission fluid
HOT. (A COLD check is used only as a reference.) If
the fluid level is low, add only enough of the proper
fluid to bring the level up to the
HOT area for a hot
check. It doesn’t take much fluid, generally less than a
pint.
Don ’t ove$ZZ. We recommend you use only fluid
labeled DEXRON@-111, because fluid with that label is
made especially for your automatic transmission.
Damage caused by fluid other than DEXRON@-I11 is
not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as
described under “How to Check.’’
When the correct fluid level is obtained, push the
dipstick back in all the way.
When to Check and Change
A good time to have it checked is when the engine oil is
changed. Refer to the Maintenance Schedule to
determine when to change
your transmission fluid. See
“Scheduled Maintenance Services” in the Index.

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.

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.

When It’s Time for New Tires
One way to tell when it’s
time for new tires is to
check the treadwear
indicators, which will
appear when your tires have
only
1/16 inch (1.6 rnm) or
less of tread remaining.
You need a new tire
if
0 You can see the indicators at three or more places
0 You can see cord or fabric showing through the tire’s
0 The tread or sidewall is cracked, cut or snagged deep
around the tire.
rubber.
enough to show cord
or fabric.
0 The tire has a bump, bulge or split.
0 The tire has a puncture, cut, or other damage that
can’t be repaired well because of the size or location
of the damage.
Buying New Tires
To find out what kind and size of tires you need, look at
the Tire-Loading Information label.
The tires installed on your vehicle when it was new had
a Tire Performance Criteria Specification (TPC Spec)
number on each tire’s sidewall. When you get new tires,
get ones with that same TPC Spec number. That way,
your vehicle will continue to have tires
that are designed
to give proper endurance, handling, speed rating,
traction, ride and other things during norrnal service on
your vehicle.
If your tires have an all-season tread
design, the TPC number will
be followed by an “MS”
(for mud and snow).
If you ever replace your tires with those not having a
TPC Spec number, make sure they
are the same size,
load range, speed rating and construction type (bias,
bias-belted or radial) as your original tires.

Treadwear
Uniform Tire Quality Grading
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration which grades tires by
treadwear, traction and temperature performance. (This
applies only to vehicles sold in the United States.) The
treadwear grade is a comparative rating based on
the wear rate
of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded
150 would wear one and a half
(1 1/2) times as well on the government course as a tire
graded
100. The relative performance of tires depends
upon the actual conditions of their use, however, and
may depart significantly from the norm due to variations
in driving habits, service practices and differences in
road characteristics and climate.
Traction - A, B, C
The traction grades, from highest to lowest are: A, B,
and C. They represent the tire’s ability to stop on wet
pavement as measured under controlled conditions on
specified government test surfaces of asphalt and
concrete.
A tire marked C may have poor traction
performance.
Warning: The traction grade assigned to this tire is basea
on braking (straight-ahead) traction tests and does not
include cornering (turning) traction.

Aluminum Wheels (If So Equipped)
Your aluminum wheels have a protective coating similar
to the painted surface of your vehicle. Don’t
use strong
soaps, chemicals, chrome polish, abrasive cleaners or
abrasive cleaning brushes
on them because you could
damage this coating. After rinsing thoroughly, a wax
may be applied.
I NOTICE:
If you have aluminum wheels, don’t use an
automatic vehicle wash that has hard silicon
carbide cleaning brushes. These brushes can take
the protective coating
off your aluminum wheels.
Tires
To clean your tires, use a stiff brush with a tire cleaner.
When applying a tire dressing always take care
to wipe
off any overspray or splash from painted surfaces.
Petroleum-based products may damage the paint finish.
Sheet Metal Damage
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.
