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.
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.

have the air cleaner in place when you’re driving.
Automatic Transaxle Fluid
(Three-Speed Only)
When to Check and Change
A good time to check your automatic transaxle 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:
In heavy city traffic where the outside temperature
In hilly or mountainous terrain.
When doing frequent trailer towing.
0 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.

Because this operation can be a little difficult, you may
choose to have this done at your Chevrolet 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
transaxle.
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
transaxle fluid.
Wait at least 30 minutes before checking the transaxle
fluid level if you have been driving:
0 When outside temperatures are above 90°F (32°C).
0 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).
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), you may
have to drive longer.

1. If you have a three speed
automatic transaxle, the
handle on the transaxle

How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind
of transaxle fluid to use. See “Recommended
Fluids and Lubricants” in the Index.
If the fluid level is low, add only enough of the proper
fluid to bring the level into the cross-hatched area

Manual Transaxle Fluid
When to Check
A good time to have it checked is when the engine oil is
changed. However, the fluid in your manual transaxle
doesn't require changing.
How to Check
Because this operation can be a little difficult, you may
choose to have this done at your Chevrolet 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.
ITICE:
Too much or too little fluid can damage your
manual transaxle.
Too much can mean that some
of the fluid could come out and fall on hot engine
1 parts or exhaust system parts, starting a fire. Be
sure to get an accurate reading if you check your
transaxle fluid.
Check the fluid level only when your engine is off, the
vehicle
is parked on a level place and the manual
transaxle is cool enough for
you to rest your fingers on
the transaxle case.

1. The manual transaxle
dipstick is located
below the brake
master cylinder,
near
the rear of the
transaxle case. Flip the
handle up and then
pull out the dipstick and clean
it with a rag
or paper towel.
2. Push it back in all the way and remove it.
3. Check both sides of the dipstick and read the lower
level. The fluid level must be between the
ADD and
FULL marks. (Note: Fluid may appear at the bottom
of the dipstick even when the fluid level is several
pints low.)
4. If the fluid level is where it should be, push the
dipstick back
in all the way and flip the handle
down. If the fluid level is low, add more fluid
as
described in the next steps.

Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. The clutch master cylinder reservoir is
filled with hydraulic clutch fluid.
It isn’t a good idea to “top off’ your clutch fluid. Adding
fluid won’t correct a leak.
A fluid loss in this system could indicate a problem.
Have the system inspected and repaired.
When to Check and What to Use
Refer to the Maintenance Schedule to determine how
often you should check the fluid level in your clutch
master cylinder reservoir and for the proper fluid. See
“Owner Checks and Services” and “Recommended
Fluids and Lubricants” in the Index.
6-24

Downloaded from www.Manualslib.com manuals search engine How to Check
You do not need to check the fluid level unless you
suspect a clutch problem.
To check the fluid level, take
the cap
off. If the fluid reaches the step inside the
reservoir, the fluid level is correct.
Engine Coolant
The cooling s stem in your vehicle is filled with
DEX-COOL
8 engine coolant. This coolant is designed
to remain in your vehicle for
5 years or 150,000 miles
(240 000 km) whichever occurs first, if you add only
DEX-COOL’ extended life 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 DEX-COOL@
coolant will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 “F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.
NOTICE:
When adding coolant, it is important that you
use only
DEX-COOL@ (silicate-free) coolant.
If coolant other than DEX-COOL is added to
the system, premature engine, heater core or
radiator corrosion may result. In addition, the
engine coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the
use of coolant other than DEX-COOL@ is not
covered by your new vehicle warranty.
6-25

Downloaded from www.Manualslib.com manuals search engine What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL@ coolant which
won’t damage aluminum parts.
If you use this mixture,
you don’t need to add anything else.
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 mixture will. Your vehicle’s coolant
warning system is set for the proper coolant
mixture. With plain water or the wrong mixture,
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 mixture of clean water and
DEX-COOL@ coolant.
NOTICE:
If you use an improper coolant mixture, your
engine could overheat and be badly damaged.
The repair cost wouldn’t be covered by your
warranty.
Too much water in the mixture 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:
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.

The surge tank is located on the passenger’s side of the
engine compartment.
A CAUTION:
Thrning the surge tank pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn you badly.
Never turn the surge tank pressure cap
-- even a
little
-- when the engine and radiator are hot.
When your engine is cold, the coolant level should be at
the FULL
COLD mark.
