If a Tire Goes Flat
It’s unusual for a tire to “blow out” while
you’re driving, especially
if you maintain
your tires properly.
If air goes out of a
tire, it’s much more likely to leak out
slowly.
But if you should ever have a
“blowout.” here are a few tips about what
to expect and what to do:
If a front tire Fails, the flat tire will create
a drag that pulls the vehicle toward that
side. Tdke your foot off
the accelerator
pedal and grip the steering wheel firmly.
Steer
to maintain lane position, then
gently brake to a stop well out
of the
traffic lane.
A rear blowout, particularly on a curve,
acts much like
a skid and may require the
same correction you’d use
in a skid. In
any rear blowout, remove your foot from
the accelerator pedal. Get the vehicle under control by steering
the way you
want the vehicle to go. It rnay be very
bumpy and noisy, but
you can still steer.
fently brake to a stop, well off the road
if possible.
If a tire goes tlat, the next section shows
how to use your jacking equipment
to
:hange a tlat tire safely.
Changing a Flat Tire
If a tire goes tlat, avoid further tire and
wheel damage by driving slowly
to a
level place.
Turn on your hazard warning
flashers.

Engine Oil Additives
Don’t add anything to your oil. Your Geo
dealer is ready to advise
if you think
something should be added.
When to Change Engine Oil
See if any one of these is true for you:
Most trips are less than 4 miles (6 km).
It’s below freezing outside and most
trips are less than 10 miles (1 6 km).
The engine is at low speed most of the
time (as
in door-to-door delivery, or
stop-and-go traffic).
You tow a trailer often.
Most trips are through dusty places.
The vehicle is frequently operated
If any one of these is true for your
vehicle, then you need to change your
and filter every
3,000 miles (5 000 km) or
3 months - whichever comes first.
If none of them is true, change oil and
filter every
7,500 miles (1 2 500 km) or
7.5 months - whichever comes first.

Engine
Coolant Heater (Engine Block
Heater)
An engine coolant heater can be a big
help
if you have to park outside in very
cold weather,
0°F (-I 8°C) or colder. If
your vehicle has this option, see “Engine
Coolant Heater”
in the Index.
What to Do with Used Oil
Did you know that used engine oil
contains elements that may be unhealthy
for your skin and could even cause
cancer? Don’t let used oil stay on your
skin for very long. Clean your skin and
nails
with soap and water, or a good hand
cleaner. Wash or properly throw away
clothing or rags containing used engine
oil. (See the manufacturer’s warnings
about
the use and disposal of oil products.)
Used oil can
be a real threat to the
environment.
If you change your own oil,
be sure
to drain all free-tlowing oil from
the filter before disposal. Don’t ever
dispose of oil by putting
it in the trash,
pouring
it on the ground, into sewers, or
into streams or bodies
of water. Instead.
recycle
it by taking it to a place that
collects used
oil. If you have a problem

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
. . .I70
ProCarManuals.com

and refill. If you use this mixture. you
don't need to add anything else.
A CAUTION:
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 mix will. Your vehicle's
cool-
ant warning system is set for the
proper coolant
mix. With plain water
or the wrong mix, 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 mix of clean
water and a proper antifreeze.
NOTICE:
If you use an improper coolant mix,
your engine could overheat and be
badly damaged. The repair cost
wouldn't be covered by your war-
ranty.
Too much water in the mix can
freeze and crack the engine, radiator,
heater core and other parts. Some conditions, such
as air
trapped in
the cooling system, can af't'ect the coolant
level
in the radiator. Check the coolant
level when the engine is cold and follow
the steps under "Adding Coolant" for the
proper way
to add coolant.
If you have to add coolant Inore than four
times
a year. have your dealer check your
cooling system.
NOTICE:
If you use the proper coolant. you
don't have to add extra inhibitors
or
additives which claim to improve thc
system. These can
be harmful.
%-Valve Engine
Adding Coolant
To Check Coolant: When your engine is

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 Schedple to
determine when to check
yoqr drake
fluid. See “Periodic Maintenance
Inspections” in the Index.
To Check Brake Fluid:
You can check the brake fluid without
taking
off the cap. Just look at the
windows on the brake fluid reservoir. The
fluid levels should be above “MIN.” If
they aren’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 levels are above
“MIN’ and below the top
of each
window.
What to Add:
When you do need brake fluid, use only
DOT-3 brake fluid
- such as Delco-
Supreme 11s (GM Part
No. 1052535).
Use new brake fluid from a sealed container
only, and always clean the brakl
fluid reservoir cap before removing it.
NOTICE:
Don’t let someone put in the
wrong kind of fluid. For example,
just a few drops of mineral-based
oil, such as engine oil, in your
brake system can damage brake system parts
so badly that they’ll
have to be replaced.
Brake fluid can damage paint, so
be careful not to spill brake fluid
on your vehicle. If
you do, wash it
off immediately. See “Appearance
Care” in the Index.
Brake Wear
Your Geo has front disc brakes and rear
drum brakes.
Disc brake pads have built-in wear
indicators that make a high-pitched
warning sound when the brake pads are
worn and new pads are needed. The
sound may come and
go or be heard all
the time your vehicle is moving (except
when you are pushing on the brake pedal
firmly).

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.

WHAT SHOULD BE DONE
Check the gear lubricant level and add if needed. See “Rear Axle” and “Four-Wheel Drive” in
the Index. A fluid loss may indicate a problem. Check the system(s), and repair the system(s) if
needed. Refer to “Scheduled Maintenance Services,” earlier in
this part, to determine when to
change the lubricant.
Inspect the complete system. Inspect brake lines and hoses for proper hookup, binding, leaks,
cracks, chafing, etc. Inspect disc brake pads for wear and rotors for surface condition. Also
inspect
drum brake linings for wear and cracks. Inspect other brake parts, including drums,
wheel cylinders, calipers, parking brake, etc. Check parking brake adjustment. You may need to
have your brakes inspected more often if your driving habits or conditions result in frequent
braking.
NOTE: A low brake fluid level can indicate worn disc brake pads which may need to be serv-
iced. Also,
if the brake system warning light stays on or comes on, something may be wrong
with either the regular or rear wheel anti-lock brake system, or both systems. See “Brake System
Warning Light” in the Index.
Check clutch pedal free travel and adjust
as necessary. See “Clutch Adjustment” in the Index. ..
