The coolant level should be at or above FULL. If it
isn’t, you may have a leak in the radiator hoses, heater
hoses, radiator, water
pump or somewhere else in the
cooling system.
Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them.
If you
do, you can be burned.
Don’t run the engine
if there is a leak. If you run
the engine, it could lose
all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
I NOTICE:
Engine damage from running your engine
without coolant isn’t covered
by your warranty.
If there seems to be no leak, with the engine on, check to
see if the electric engine fan is running. If the engine is
overheating, the
fan should be running. If it isn’t, your
vehicle needs service.

If your vehicle is certified to meet California Emission
Standards (indicated
on the underhood tune-up label), it
is designed to operate on fuels that meet California
specifications. If such fuels are not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp on
your instrument panel may turn on and/or your vehicle
may fail a smog-check test. If this occurs, return to your
authorized Geo dealer for diagnosis to determine the
cause
of failure. In the event it is determined that the
cause
of the condition is the type of fuels used, repairs
may not be covered by your warranty.
In Canada, some gasolines contain an octane-enhancing
additive called
MMT. If you use such fuels, your
emission control system performance may deteriorate
and the malfunction indicator lamp
on your instrument
panel may turn
on. If this happens, return to your
authorized Chevrolet/Geo dealer for service.
To provide cleaner air, all gasolines are now required to
contain additives that will help prevent deposits
from
forming in your engine and fuel system, allowing your
emission control system
to function properly. Therefore,
you should not have to add anything to the fuel.
In
addition, gasolines containing oxygenates, such as ethers
and ethanol, and reformulated gasolines may be available
in your area to help clean the air. General Motors
recommends that you use these gasolines
if they comply
with the specifications described earlier.
1 NOTICE:
,
Your vehicle was not designed for fuel that
contains methanol. 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.

Checking Things Under the Hood
A CAUTICV: I
An electric fan under the hood can start up and
injure
you even when the engine is not running.
Keep hands, clothing and tools away from any
underhood electric fan. Don’t reach through the
grille to release the underhood lever.
To open the hood, first pull the release handle inside the
glove box.
Things that burn can get on hot engine parts and
start
a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber.
You or others
could
be burned, Be careful not to drop or spill
things that will
burn onto a hot engine.

Before closing the hood, be sure all the filler
caps are on.
Then lift the hood to relieve pressure on the hood prop.
Remove the hood prop from the slot in the hood and
return the prop
to its retainer. Then let the hood down
and close
it firmly.
Engine Oil
If the engine oil
pressure light on the
instrument panel comes
on, it means
you need
to check
your engine oil level
right away.
For more information,
see “Engine Oil Pressure Light”
in the Index. You should check your engine oil level
regularly; this is an added reminder. It’s a good
idea
to check your engine oil 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
drain back into the oil
pan. If you don’t, the oil
dipstick might not show
the actual level.

Checking Engine Oil
Pull out the dipstick and clean it with a paper towel or
iApBrh, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.
When to Add Oil
If the oil is at or below the ADD mark, then you’ll need
to
add some oil. But you must use the right kind. This
part explains what kind of oil to use. For crankcase
capacity, see “Capacities
and Specifications” in the Index.
NOTICE:
Don’t add too much oil. If your engine has so
much oil that the oil level gets above the upper
mark that shows the proper operating range,
your engine could be damaged.
Just fill it enough to put the level somewhere in the
proper operating range. Push the dipstick all the way
back in when you’re through.

~ Operating the
engine with the air cleaner off can
~ cause you or others to be burned. The air cleaner
~ not only cleans the air, it stops flame if the engine
backfires.
If it isn’t there, and the engine
backfires,
you could be burned. Don’t drive with
it
off, and be careful working on the engine with
the air cleaner off.
I NOTICE:
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get
into your
engine, which will damage it. Always
have the
air cleaner in place when you’re driving.

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.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
0 In heavy city traffic where the outside temperature
regularly reaches
90°F (32” C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not
require changing.
See “Scheduled Maintenance Services” in the Index.

How to Check
Because this operation can be a little difficult, you
may choose to have t,his 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 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:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
@ In heavy traffic -- especially in hot weather.
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).
Checking Transmission Fluid Hot
Get the vehicle warmed up by driving about 15 miles
(24 km) when outside temperatures are above 50°F
(10°C). If it's colder than 50°F (lO"C), drive the
vehicle
in DRIVE (D) until the engine temperature gage
moves and then remains steady for
10 minutes. Then
follow the hot check procedures.
Checking 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 (lO°C), you may have to
idle the engine longer. Should the fluid level be low
during
a cold check, you must perform a hot check
before adding fluid. This will give
vou a more accurate
reading of the fluid level.
