Downloaded from www.Manualslib.com manuals search engine If No Steam Is Coming From Your Engine
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. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
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 . p~
the vehicle until it cools down. *! ?rLw&pa
You may decide not to lift the hood but to get service
help right away.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (@)
or DRIVE (D).

don’t do anything else
until it cools down. A CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them.
If you
do, you can be burned.
Don’t run the engine if there is a leak.
If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
The coolant level should be at or above the COLD mark.
If it isn’t, you may have a leak in the radiator hoses,
heater hoses, radiator, water
pump or somewhere else in
the cooling system.
1 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 fans are running. If the engine
is overheating, both fans should be running.
If they
aren‘t, your vehicle needs service.

If you haven’t found a problem yet, but the coolant level
isn’t at
the COLD mark, add a 50/50 mixture of
clean water (preferably distilled) and DEX-COOL TM
(orange-colored, silicate-free) antifreeze at the coolant
recovery tank. (See “Engine Coolant” in the
Index for
more information.)
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
DEX-COOL TM antifreeze.
1 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.

engine parts. Coolant contains ethylene glycol
and it will burn if the engine parts are hot

When the coolant in the coolant recovery tank is at the

If the overheat warning continues, there's one more
thing you can try.
You can add the proper coolant mix

Downloaded from www.Manualslib.com manuals search engine If You’re Stuck: In Sand, Mud,
Ice or Snow I NOTICE:
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.
Spinning your wheels can destroy parts of your
vehicle as well as the tires.
If you spin the wheels
too fast while shifting your transaxle back and
forth, you can destroy your transaxle.
If you let your tires spin at high speed, they can
explode, and you or others could be injured.
And, the transaxle
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.
For information about using tire chains on your vehicle,
see “Tire Chains”
in the Index.
Rocking Your Vehicle to Get it Out
First, turn your steering wheel left and right. That will
clear the area around your front wheels. Then shift back
and forth between REVERSE
(R) and a forward gear,
spinning
the wheels as little as possible. Release the
accelerator pedal while you shift, and press lightly on
the accelerator pedal when the transaxle is
in gear. If
that doesn’t get you out after
a few tries, you may need
to be towed out.
If you do need to be towed out, see
“Towing Your Vehicle”
in the Index.

Downloaded from www.Manualslib.com manuals search engine How to Add Fluid Engine Coolant
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 on
the dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough fluid at the
dipstick hole to bring
it to the proper level. It doesn’t
take much fluid, generally less than
a pint (OSL).
Don ’t overfill. We recommend you use only fluid
labeled DEXRON@-111, because fluid with that
label is made especially for your automatic transaxle.
Damage caused by fluid other than DEXRON@-I11
is
not covered by your new vehicle warranty.
0 After adding fluid, recheck the fluid level as
described under “How to Check.”
0 When the correct fluid level is obtained, push the
dipstick back
in all the way. The cooling
system in your vehicle is filled with new
DEX-COOL
TM (orange-colored, silicate-free) engine
coolant. This coolant is designed
to remain in your
vehicle for
5 years or 100,000 miles ( 166 000 km),
whichever occurs first.
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.
A 50/50 mixture of water and the proper coolant for
your Chevrolet will:
0 Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights and gages work as they
should.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
When adding coolant it is important that you use
DEX-COOL
TM (orange-colored, silicate-free)
coolant meeting
GM Specification 6277M.
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.
What to
Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL TM (orange-colored,
silicate-free) antifreeze that meets
GM Specification
6277M, 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.
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 DEX-COOL
TM (orange-colored,
silicate-free) antifreeze.

Downloaded from www.Manualslib.com manuals search engine 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.
I 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.
Checking Coolant
r-
When your engine is cold, the coolant level should be at
the
COLD mark or a little higher. When .your engine is
warm,
the level should be up to the HOT mark or a
little higher.

COOLANT
If this light comes on, it
means you’re low on
engine coolant.
Adding Coolant
If you need more coolant, add the proper mix at the
coolant recovery tank.
If the coolant recovery tank is completely empty, add
coolant
to the radiator. (See “Engine Overheating” in
the Index.)
Thrning 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:
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.
