Four- Wheel Drive
Most
lubricant checks in this section also
apply to four-wheel-drive vehicles.
However, they have
two additional
systems that need lubricatiog.
Transfer Case
When to Check qnd Change Lubricant
Refer to the Maintenance Schedule to
determine how often to check the
lubricant and when to change
it. See
“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. Add enough lubricant to raise
the level to the bottom of the filler plug
hole.
What to Use
Refer to the Maintenance Schedule to
determine what kind of lybricant to use.
See “Recommended Fluids and
Lubricants”
in the Index.
Front Axle
When
to Check and Change Lubricant
Refer to the Maintenance Schedule to a
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.
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.
The proper coolant for your Geo will:
Give freezing protection down to
-20°F (-29”C), or -34°F (-37°C)
in
Canada and for vehicles with the cold
climate option.
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
6038-M,” which won’t damage aluminum
parts.
You can also use a recycled coolant
conforming to
“GM Specification
6038-M”
with a complete coolant flush

dake certain that all wheel nuts are
lroperly tightened. See “Wheel Nut
’orque”
in the Index.
Rust or dirt on a wheel, or on the
pas to which it is fastened, can
make wheel nuts become loose &er
a time. The wheel
could come off and
cause
an accident. When you change
a wheel, remove any rust or dirt from
places where the wheel attaches to
the vehicle. In an emergency, you
can use a cloth or a paper towel to
do this; but be sure to use a scraper
or wire brush later, if you need to,
to get all the rust or dirt off. (See
“Changing
a Rat Tire” in the Index.)

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 based on braking
(straight-ahead) traction tests and does
not include cornering (turning) traction.
Temperature - A, B, C
The temperature grades are A (the
highest),
B, and C, representing the tire’s
resistance to the generation of heat and its
ability to dissipate heat when tested under
controlled conditions on a specified
indoor laboratory test wheel. Sustained
high temperature can cause the material
of the tire to degenerate and reduce tire
life, and excessive temperature can lead to
sudden tire failure. The grade
C
corresponds to a level of performance
which all passenger car tires must meet
under the Federal Motor Vehicle Safety
Standard
No. 109. Grades B and A
represent higher levels of performance on
the laboratory test wheel than the
minimum required by law.
Warning: The temperature grade for this
tire is established for a tire that is properly
inflated and not overloaded. Excessive
speed, underinflation, or excessive
loading, either separately or
in
combination, can cause heat buildup and
possible tire failure.
These grades are molded on the sidewalls
of passenger car tires.
While the tires available as standard or
optional equipment on General Motors
vehicles may vary with respect to these
grades, all such tires meet General Motors
performance standards and have been
approved for use on General Motors
vehicles. All passenger type
(P Metric)
tires must conform to Federal safety
requirements in addition to these grades.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned
and balanced carefully at the factory to give
you the longest tire life and best
overall performance.
In most cases, you will not need to have
your wheels aligned again. However, if
you notice unusual tire wear or your
vehicle pulling one way or the other, the
alignment may need to be reset. If you
notice your vehicle vibrating when
driving on a smooth road, your wheels
may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked or
badly rusted. If wheel nuts keep coming
loose, the wheel, wheel bolts, and wheel
nuts should be replaced. If the wheel
leaks air, replace it (except some
aluminum wheels, which can sometimes
be repaired). See your Geo dealer if any
of these conditions exist.
Your dealer will know the kind of wheel
you need.
Each new wheel should have the same
load carrying capacity, diameter, width,
offset, and be mounted the same way as
the one it replaces.

Service and Appearance Care
If you need to replace any of your wheels,
wheel bolts, or wheel nuts, replace them
only
with new GM original equipment
parts. This way, you
will be sure to have
the right wheel, wheel bolts, and wheel
nuts for your Geo model.
NOTICE:
The wrong wheel can also cause
problems
with bearing life, brake
cooling, speedometer/odometer
calibration, headlight aim, bumper
height, vehicle ground clearance,
and
tire or tire chain clearance to the
body and chassis.
Used Replacement Wheels
A CAUTION:
Putting a used wheel on your vehicle
is dangerous. You can’t know how
it’s been used or how many miles it’s
been driven. It could
fail suddenly
and cause an accident.
If you have
to replace a wheel
use a new GM
original equipment wheel.
Tire Chains
NOTICE:
Use tire chains only where legal and
only when you must. Use only SAE
Class “S” type chains that are the
proper size for your tires. Install them
on the tires of the drive axle (four-
wheel drive vehicles can use chains
on both axles). Tighten them
as
tightly as possible with the ends
securely fastened. Drive slowly and
follow the chain manufacturer’s
instructions.
If you can hear the
chains contacting your vehicle, stop
and retighten them.
If the contact
continues, slow down until
it stops.
Driving too fast with chains
on will
damage your vehicle.

Wipe off dust with a soft cotton cloth
moistened with clean, cool or
lukewarm water. Don’t use a “dry”
cloth. Wipe in one direction only, not
back and forth.
To remove frost, snow or ice, use
lukewarm water. Don’t use a scraper
or any de-icing fluids.
Wash the windows with a soft cloth
and clean, cool or lukewarm water.
Never use a dry cloth, hot water,
strong soap or detergent, solvents or
harsh cleaning agents. Rinse
thoroughly and wipe with a slightly
moist soft, clean cloth.

Don’t put any labels, stickers or tape
on windows. It’s hard to remove
adhesives left on the window when
such items are removed.
If a sticker or
label must be removed, remove any
adhesive left on the window while the
adhesive is still soft and sticky. Press
on a new sticker or piece of tape and
then lift it off again; keep doing this
until all the adhesive lifts off with
the sticker or tape.
Aluminum Wheels (If So Equipped)
Your aluminum wheels have a protective
zoating similar to the painted surface
3f your vehicle. Don’t use strong soaps,
:hemicals, chrome polish, abrasive
cleaners or abrasive cleaning brushes
on them because you could damage this
coating. After rinsing thoroughly, a wax
mi ay be applied.
NOTICE:
If you have aluminum wheels, don’t
use an automatic car wash that has
hard silicon carbide cleaning brushes.
These brushes can take
off the
protective coating.
Tires
Your Geo dealer has a GM White Sidewall
Tire Cleaner. You can use a stiff brush
with the 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.
Weatherstrips
Silicone grease on weatherstrips will
make them last longer, seal better, and
not stick or squeak. Apply silicone
grease with a clean cloth at least every
six months. During very cold, damp
weather more frequent application may
be required. (See “Recommended Fluids
and Lubricants” in the Index.)
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.
