loing Your Own Service Work
F YOU want to do some of your own
ervice work, you’ll want to get the
lroper Geo Service Manual.
It tells you
mch more about how to service your
;eo than this manual can. To order the
. . .I56
xoper service manual, see “Service
Publications” in the Index.
You should keep a record with all parts
receipts and list the mileage and the date
Df any service work you perform. See
“Maintenance Record” in the Index.
NOTICE:
If you try to do your own service
work without knowing enough about
it, your vehicle could be damaged.
Fuel
Use regular unleaded gasoline rated at 87
octane or higher. It should meet
specifications ASTM D4814
in the U.S.
and CGSB 3.5-92 in Canada. These fuels
should have the proper additives,
so you
should not have to add anything to the
fuel.
In the U.S. and Canada, it’s easy to be
sure you get the right kind of gasoline
(unleaded). You’ll see “UNLEADED”
right on the pump. And only unleaded
nozzles will
fit into your vehicle’s filler
neck.
Be sure
the posted octane is at least 87. If
the octane is less than 87, you may get a
heavy knocking noise when you drive. If
it’s bad enough, it can damage your
engine.
If you’re using fuel rated at 87 octane or
higher and you still hear heavy knocking, your engine needs service.
But don’t
ProCarManuals.com

worry if you hear a little pinging noise
when you’re accelerating or driving up a
hill. That’s normal and you don’t have to
buy a higher octane fuel to get rid of
pinging. It’s the heavy, constant knock
that means you have a problem.
What about gasoline
with blending
materials that contain oxygen
(oxygenates), such as MTBE or alcohol?
MTBE
is “methyl tertiary-butyl ether.”
Fuel that is no more than
15% MTBE is
fine for your vehicle.
Ethanol
is ethyl or grain alcohol.
Properly-blended fuel that
is no more
than
10% ethanol is fine for your vehicle.
Methanol is methyl or wood alcohol.
NOTICE:
Fuel that is more than S% methanol
is bad for your vehicle. Don’t use it.
It can corrode metal parts
in your fuel
system and also damage plastic and
rubber parts. That damage wouldn’t
be covered under your warranty. And
even
at 5% or less, there must be
“cosolvents” and corrosion prevent-
ers
in this fuel to help avoid these
problems.
Gasolines for Cleaner Air
Your use of gasoline with deposit control
additives
will help prevent deposits from
forming
in your engine and fuel system.
That helps keep your engine
in tune and
your emission control system working
properly. It’s good for your vehicle, and
you’ll be doing your part
for cleaner air.
Many gasolines are now blended with
oxygenates. General Motors recommends
that you use gasolines
with these blending
materials, such as MTBE and ethanol. By
doing
so, you can help clean the air,
especially
in those parts of the country
that have high carbon monoxide levels.
In addition, some gasoline suppliers are
now producing reformulated gasolines.
These gasolines are specially designed to
reduce vehicle emissions. General Motors
recommends that you use reformulated
gasoline.
By doing so, you can help clean
the air, especially
in those parts of the
country that have high ozone levels.
You should ask your service station
operators
if their gasolines contain deposit
control additives and oxygenates, and
if
they have been reformulated to reduce
vehicle emissions.
Fuels in Foreign Countries
If you plan on driving in another country
outside the
U.S. or Canada, unleaded fuel
may be hard to find.
Do not use leaded
gasoline. If you use even one tankful,
your emission controls won’t work well
or at all. With continuous use, spark plugs
can get fouled, the exhaust system can
corrode, and your engine oil can
deteriorate quickly. Your vehicle’s oxygen
sensor
will be damaged. All of that means
costly repairs that wouldn’t be covered by
your warranty.
To check on fuel availability, ask an auto
club, or contact a major oil company
that
does business in the country where you’ll
be driving.
You can also write us
at the following
address for advice. Just tell us where
you’re going and give your Vehicle
Identification Number
(VIN).

Be careful not to spill gasoline. Clean
gasoline from painted surfaces as soon as
possible. See “Cleaning

If you need a new cap, be sure to get

Engine Oil
It’s a good idea to check your engine oil
level every time you get fuel. In order to
get an accurate reading,
the oil must be
warm and the vehicle
must be on level
ground.
Turn off the engine and give
the oil a few
minutes
to drain back into the oil pan. If
you don’t, the oil dipstick might not show
the actual level.
To Check Engine Oil
Pull out the dipstick and clean it with a
paper towel or cloth, then push it back in
all the way. Remove it again, keeping the
tip lower.

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

stop-and-go traffic).
You tow a trailer often.
Most trips are through dusty places.

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.

I A utomatic Transmission FIuid
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 Geo dealership 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 tluid 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 tluid. Wait
at least 30 minutes before checking
the transmission fluid level
if you have
been driving:
0 When outside temperatures are above
0 At high speed for quite a while.
0 In heavy traffic - especially in hot
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).
To check transmission fluid hot: Get the
vehicle warmed
up by driving about IS
miles (24 km) when outside temperatures
are above 50°F
( 10°C). If it’s colder than
50°F (IOOC), drive the vehicle in “D”
(Third Gear) until the engine temperature
gage moves
and then remains steady for
ten minutes. Then follow the hot check
procedures.
To check transmission fluid cold: A cold
check is made after the vehicle has been
sitting for eight hours or more
with the
engine off
and is used only as a reference.
Let
the engine run at idle for five minutes
if outside temperatures are 50°F (10°C)
or more. If it’s colder than 50°F (IO’C),

may have to idle the engine longer.

3. Check both sides of the dipstick, and
read the lower level. The fluid level
must be in the “COLD’ area for a
cold check or
in the “HOT” area or
cross-hatched area for a hot check.
4. If the fluid level is in the acceptable
range, push the dipstick back

How to Add Fluid
Refer to the Maintenance Schedule to
determine what kind of transmission fluid
to use. See “Recommended Fluids and
Lubricants”
in the Index.
[f the fluid level is low, add only enough
of the proper fluid to bring the level up to
the “COLD” area for a cold check or the
“HOT” area for a hot check. It doesn’t take
much fluid, generally less than a
pint.
Don’t overfill. We recommend you use
only fluid labeled DEXRON@-III
or
DEXRON@-IIE, because fluids with that
label are made especially for
your
automatic transmission. Dama e caused
