If No Steam Is Coming from Your
Engine:
If you get the overheat warning but see
or hear no steam,
the problem may not
be too serious. Sometimes the engine
can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high speed driving.
Idle for long periods in traffic.
Tow a trailer. If you
get the overheat warning with no
sign of steam, try this for

highest fan speed and open
the
window as necessary.
3. If you’re in a traffic jam, shift to
N (Neutral).
If
you no longer have the overheat
warning, you can drive. Just to be safe,
drive slower for about ten minutes. If
the warning doesn’t come back on, you
can drive normally.
If the warning continues, pull over,
stop, and park your vehicle right away.
If there’s still no sign of steam, you can
idle the engine for two
or three minutes
while you’re parked, to see if the
warning stops. But then, if you still have
the warning, TURN OFF THE
ENGINE AND GET EVERYONE OUT
OF THE VEHICLE until it cools down.
You may decide not to lift the hood but
to get service help right away.

How to Add Coolant to the Coolant
Recovery
Tank
If you haven’t found a problem yet, but
the coolant level isn’t at or above
FULL, add a 50/50 mixture of clean
water
(preferably distilled) and the
proper antifreeze at the coolant recovery
tank. (See “Engine Coolant”
in the
Index for more information about the
proper coolant mix.)
A Adding only plain water to
L 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 coolant 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.

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. Take 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 may
be
very bumpy and noisy, but you can
still steer. Gently brake to a stop, well
off the road
if possible.
If your tire goes flat, the next section
shows how to use your jacking
equipment to change a flat tire safely.
ChanginQ a Flat lire
If a tire goes flat, avoid further tire and
wheel damage by driving slowly to a
level place. Turn
on your hazard
warning flashers.

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
Give boiling protection up to 258°F
Protect against rust and corrosion.

What to Use:
Use a mixture of one-half clean water
(preferably distilled) and one-half
antifreeze or approved recycled coolant
that meets “GM Specification 6038M,”
which won’t damage aluminum parts.
Also use GM Engine Coolant
Supplement (sealer) with a complete
coolant change. If you use these, you
don’t need to add anything else.

performance. (This applies only to
vehicles sold in the United States.)
Treadwear
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 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
