missing insulation. If they do, you could get a shock.
The vehicles could be damaged,
too.
6. Positive (+) goes to positive (+) and negative (-)
goes to negative (-) or a metal engine part. Connect
the red positive
(+) cable to the positive (+) terminal
of the vehicle with the dead battery. Use a remote
positive
(+) terminal if the vehicle has one.
7. Don’t let the other end touch metal. Connect it to the
positive
(+) terminal of the good battery. Use a
remote positive (+) terminal if the vehicle has one.
8. Now connect the black negative (-) cable to the good
battery’s negative
(-) terminal. Don’t let the other
end touch anything until the next step.

The other end of the negative cable doesn't go to the
dead battery. It goes to a heavy unpainted metal part
on the engine
of the vehicle with the dead battery.
Attach the cable at least
18 inches (45 cm) away
from the dead battery, but not near engine parts that
move. The electrical connection
is just as good there,
but
the chance of sparks getting back to the battery is
much less.
Now start the vehicle with the good battery and run
the engine for a while.
Try to start the vehicle with the dead battery. If it won't
start after a few tries, it probably needs service.
12. Remove the cables in reverse order to prevent
electrical shorting. Take care that they don't touch
each other
or any other metal.

Engine Overheating
You will find a coolant temperature gage on your Geo
instrument panel.
If Steam Is Coming From Your Engine

If No Steam Is Coming From Your Engine
I NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered by your warranty.
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 a minute or
so:
1. If you have an air conditioner, turn it off.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- DRIVE (D) for automatic transmissions.
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 ofthe
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.

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.
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 the FULL mark, add a 50 mixture of
clean water (preferably distilled) and a proper antifreeze
at the coolant recovery tank. (See “Engine Coolant”
in
the Index for more information about the proper coolant
mix.)
ProCarManuals.com

I NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts. Use
the recommended coolant.
When the coolant in the coolant recovery tank is at or
above the
FULL mark, start your vehicle.
If the overheat warning continues, there's one more
thing
you can try. You can add the proper coolant mix
directly to the radiator, but be sure the cooling system is
cool before you do it.

6. Start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch out for the
engine fan.
7. By this time the coolant level inside the radiator
filler neck may be lower.
If the level is lower, add
more
of the proper mix through the filler neck until
the level reaches the base of the filler neck.
8. Then replace the pressure cap. At any time during
this procedure
if coolant begins to flow out of the
filler neck, reinstall the pressure cap. Be sure the
arrows on the pressure cap line up like this.

Fuel
NOTICE:
If you try to do your own service work without
knowing enough about it, your vehicle could be
damaged.
Use regular unleaded gasoline rated at 87 octane or
higher. It should meet specifications ASTM D4814 in
the United States 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 United States 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 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 5% 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
preventers 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.
