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:
0 Climb a long hill on a hot day.
0 Stop after high-speed driving.
0 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
-- AUTOMATIC OVERDRIVE (a) or
DRIVE (D) for automatic transmissions.
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about
10 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.

Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at FULL COLD, add a
50/50 mixture of clean water
(preferably distilled) and DEX-COOL@ (silicate-free)
antifreeze
at the coolant recovery tank. (See “Engine
Coolant’’ in the Index for more information.)
A CAUTION:
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.
CAUTION: (Continued)
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 DEX-COOL@ coolant.
I 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.

Downloaded from www.Manualslib.com manuals search engine 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
FULL COLD, 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.

If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your hazard
warning flashers.
-
/ CA, TION:
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. nrn 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.
The following steps will tell you how to use the jack and
change
a tire.

Don’t add anything to your oil. Your Chevrolet dealer is
ready to advise if you think something should be added.
When to Change Engine Oil
If any one of these is true for you, use the short tripkity
maintenance schedule:
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
Most trips are through dusty areas.
You frequently tow a trailer or use a carrier on top of
your vehicle.
The vehicle is used for delivery service, police, taxi
or other commercial application.
Driving under these conditions causes engine oil
to
break down sooner. If any one of these is true for your
vehicle, then
you need to change your oil and filter
every
3,000 miles (5 000 km) or 3 months -- whichever
occurs first.
(See “Change Oil Indicator” in the Index.) If
none
of them is true, use the long triphighway
maintenance schedule. Change the oil and filter every
7,500 miles (1 2 500 km) or I2 months -- whichever
occurs first. Driving
a vehicle with a fully warmed
engine under highway conditions causes engine oil to
break down slower.
(See “Change Oil Indicator” in the Index.)
What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don’t let used oil stay on your skin
for very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil. (See
the manufacturer’s warnings about the use and disposal
of oil products.)
Used oil can be a real threat
to the environment. If you
change your own oil, be sure
to drain all free-flowing oil
from the filter before disposal. Don’t ever dispose
of oil
by putting it in
the trash, pouring it on the ground, into
sewers,
or into streams or bodies of water. Instead,
recycle it by taking
it to a place that collects used oil. If
you have a problem properly disposing of your used oil,
ask your dealer, a service station or a local recycling
center for help.

The cooling s stem in your vehicle is filled with
DEX-COOL 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 or
if you need to add coolant to your
radiator, see “Engine Overheating” in the Index.
d
A 50/50 mixture of water and DEX-COOL@
coolant will:
0 Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 265 “F (1 29°C).
0 Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 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 silicated coolant 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.

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. Use
GM Engine Coolant
Supplement (sealer)
(GM Part No. 3634621) with any
complete coolant change.
If you use this mixture, you
don’t need to add anything else.
CAUTION:
Adding only plain water to your cooling syste.m
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
DEX-COOL@ coolant.
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.
[f you have to add coolant more than four times a year,
lave your dealer :ck 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.

Using the wrong fluid can badly damage
brake system parts. For example, just a few
drops of mineral-based oil, such
as engine
oil, in your brake system can damage brake
system parts
so badly that they’ll have to be
replaced. Don’t let someone put in the
wrong kind
of fluid.
If you spill brake fluid on your vehicle’s
painted surfaces, the paint finish can be
damaged. Be careful not to spill brake fluid
on your vehicle.
If you do, wash it off
immediately. See “Appearance Care” in
the Index.
Brake Wear
Unless you have the four-wheel disc brake option, your
Chevrolet has front disc brakes and rear drum brakes.
Disc brake pads have built-in wear indicators that make a
high-pitched warning sound when the brake pads are worn and new pads
are needed. The sound may come and go or
be heard
all the time your vehicle is moving (except when
you are pushing
on the brake pedal firmly).
The brake wear warning sound means that soon
your brakes won’t work well. That could lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
I NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
