~ 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.

lever through each gear range, pausing for about
three seconds
in each range. Then, position the shift
lever
in PARK (P).
Let the engine run at idle for three minutes or more. Then,
without shutting
off the engine, follow
these steps:
1.
2.
Pull out the dipstick
and wipe it with
a clean
rag or paper towel.
Push it back
in all the
way, wait three seconds
and then pull it back
out again.

What to Use
Refer to the Maintenance Schedule to determine what
W 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.
A 50/50 mixture of water and the proper coolant for
your Geo will:
Give freezing protection down to -33 “F (-36°C).
0 Give boiling protection up to 258°F (125°C).
Protect against rust and corrosion.
Help keep the proper engine temperature,
Let the warning lights and gages work as
they should.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half antifreeze that meets
GM
Specification 1825-M, which won’t damage aluminum
parts. You can also use a recycled coolant conforming
to
GM Specification 1825-M with a complete coolant flush
and refill. If you use this mixture, you don’t need to add
anything else.
/i CAUTTON:
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 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 the proper antifreeze.
6-24
ProCarManuals.com

NOTICE:
If you use an improper coolant mix, your engine
could overheat and be badly damaged. The
repair cost wouldn’t be covered by
your
warranty. Too much water in the mix can freeze
and crack the engine, radiator, heater core and
other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
NOTICE:
r
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.
Checking Coolant
When your engine is cold, the coolant level should be at
LOW, or
a little higher. When your engine is warm, the
level should be
up to FULL, or a little higher.
Adding Coolant
If you need more coolant, add the proper mix at the
coolant recovery tank.

A RI
/t! CAUTION:
lhrning the radiator pressure cap when the
engine
and radiator are hot can allow steam and,
scalding liquids to blow out and burn
you badly.
With the coolant recovery tank, you will almost
never have to add coolant
at the radiator.
Never turn the radiator pressure cap -- even a
little -- when the engine and radiator are hot.
Add coolant mix at the recovery tank, but be careful not
to spill it.
'
A CAUTION:
Radiator Pressure Cap
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.
NOTICE:
Your radiator cap is a 13 psi (90 kPa)
pressure-type cap and must be tightly installed to
prevent coolant
loss and possible engine damage
from overheating. Be sure the arrows on the cap
line up with the overflow tube on the radiator
filler neck.
When you replace your radiator pressure cap, an AC@
cap is recommended.
Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine coolant system. The thermostat stops the
flow of coolant through the radiator until the coolant
reaches a preset temperature.
When you replace
your thermostat, an AC@ thermostat
is recommended.

Power Steering Fluid
When to Check Power Steering Fluid
It is not necessary to regularly check power steering fluid
unless you suspect there
is a leak in the system or you hear
an unusual noise. A fluid loss in this system could indicate
a problem. Have the system inspected and repaired.
How To Check Power Steering Fluid
When the engine compartment is cool, unscrew the cap
and wipe the dipstick with a clean rag. Replace the cap
and completely tighten it. Then remove the cap again
and look at the fluid level on the dipstick.
0 When the engine compartment is hot, the level
@ When the engine compartment is cool, the level
should
be at the

system fixed, since a leak means that sooner or later your
brakes won’t work well, or won’t work at all.
So, it isn’t a good idea to “top off’ your brake fluid.
Adding brake fluid won’t correct a leak.
If you add fluid
when your linings
are worn, then you’ll have too much
fluid when
you get new brake linings. You should add
(or remove) brake fluid, as necessary, only when work ’is
done on the brake hydraulic system.
A CAUTION:
If you have too much brake fluid, it can spill on
the engine. The fluid will burn if the engine is hot
enough.
You or others could be burned, and your
vehicle could be damaged. Add brake fluid only
when work
is done on the brake hydraulic system.
Refer to the Maintenance Schedule to determine when to
check your brake fluid. See “Periodic Maintenance
Inspections” in the Index.
Checking Brake Fluid
You can check the
brake fluid without taking
off the cap.
Just look at the windows on the brake fluid reservoir.
The fluid levels should be above
MIN, If they aren’t,
have your brake system checked
to see if there is a leak.
After work is done on the brake hydraulic system, make
sure the levels
are above MIN and below the top of
each window.
