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 50/50 mixture of
clean water (preferably distilled) and a proper antifi-eeze at
the coolant recovery tank. (See “Engine Coolant” in the
Index for more information about the proper coolant mix.)
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 coolant warning
system is set
for the proper coolant mix. With
plain water or the wrong mix, your engine couId
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:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant
mix.

You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn if the engine parts are hot
enough. Don’t spill coolant on a hot engine.
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.

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.

If a Tire Goes Plat
It’s unusual for a tire to “blow out” while you’re driving,
especiaIIy
if you maintain your tires properly. If air goes
out
of a tire, it’s much more likely to leak put 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, and 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 a tire goes flat, the next part shows how to use your
jacking equipment to change a flat tire safely.
Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly
to a level place. Turn on your hazard
warning flashers.
I
’ A CAUTION:
Changing a tire can cause an injury. The vehicle
can slip
off the jack and roll over you or other
people.
You and they could be badly injured.
Find
a level place to change your tire. To help
prevent the vehicle
from moving:
1. Set the parking brake firmly.
2. Put an automatic transmission shift
lever in PARK (P) or shift a manual
transmission to FIRST (1) or
REVERSE
(R).
3. If you have a four-wheel-drive vehicle,
be sure the transfer case is in
a drive
gear
-- not in NEUTRAL (N).
4. Turn off the engine.
To be even more certain the vehicle won’t move,
you can put blocks at the front and rear of the
tire farthest away from the one being changed.
That would be the tire on the other side of the
vehicle,
at the opposite end.

If You’re Stuck: In Sand, Mud, Ice
or Snow
What you don’t want to do when your vehicle is stuck is
to spin your wheels too fast. The method known as
“rocking” can help you get out when you’re stuck, but
you must use caution.

let your tires spin at high speed, they can
explode, and you or others could be injured. And,
the transmission or other parts
of the vehicle can
overheat. That
could cause an engine
compartment fire or other damage. When you’re
stuck, spin the wheels as little as possible. Don’t
spin the wheels above
35 mph (55 km/h) as shown
on the speedometer.
I NOTICE:
Spinning your wheels can destroy parts of your
vehicle as well as the tires.
If you spin the wheels
too
fast while shifting your transmission back
and forth, you can destroy your transmission.

A CAUTION:
~ ~~
You can be injured and your vehicle could be
damaged if you try to
do service work on a
vehicle without knowing enough about it.
Be sure you have sufficient knowledge,
experience, and the proper replacement
parts and tools before you attempt any
vehicle maintenance task.
0 Be sure to use the proper nuts, bolts and
other fasteners. “English,’ and “metric”
fasteners can be easily confused.
If you use
the wrong fasteners, parts can later break
or fall off. You could be hurt.
Fuel
Use regular unleaded gasoline rated at 87 octane or higher.
At a
minimum, it should meet specifications ASTM D4814
in the United States and CGSB 3.5-M93 in cana$a
Improved gasoline specifications have been developed by
the American Automobile Manufacturers Association
(AAMA) for better vehicle performance and engine
protection.
Gasolines meting the AAMA specification
could provide improved driveability
and emission control
system protection compared to other gasolines.
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.

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.
