If you see or hear escaping steam or have other reason to suspect there is a
serious overheat condition, stop and park the vehicle as soon as it is safe
to do so and turn off the engine immediately and get out of the vehicle.
The cooling system may overheat if the coolant level is too low, if there is a
sudden
loss of coolant (such as a worn hose splitting), or if other problems occur. It may also temporarily overheat during severe operating conditions
such as:
• climbing a long hill on a hot day,
• stopping after high-speed driving,
• idling for long periods in trallic, or
• towing a trailer.
I! the Engine Coolant Temperature light comes on (or if you have an Engine
Coolant Temperature gage and it shows an overheat condition), or you have
any reason to suspect the engine may be overheating:
• tfyour air conditioner is on, turn it off.
• If you are stopped in traffic, shift the transaxle to "N" (Neutral).
If the warning light does not go off (or engine coolant temperature does not
start to drop) within a minute
Or two:
• Pull over, stop and park the vehicle as soon as it is safe to do so.
• Let the engine run at normal idle speed for two or three minutes.
I! the warning light does not go off (or engine coolant temperature does not
start to drop),
turn off the engine and get out of the car, then proceed as
follows:
CAUTION: To help avokt being burned:
• DO NOT OPEN ntE HOOD if you see or hear steam or coolant escaping from the engine compartment. Wait until no steam or coolant can be seen or heard before opening the hood.
• DO NOT REMOVE THE RADIATOR CAP or coolant RECOVERY TANK CAP IF THE COOLANT IN THE RECOVERY TANK IS BOIUNG. Also do not remove the radiator
cap while the engine and radiator are still hot Scalding fluid and steam can be blown out under pressure if eHher cap is taken off too soon.
I! no steam or coolant can be seen or heard, raise the engine hood. If the
coolant is boiling, wait until it stops before proceeding. Look at the

or above the
"FULL HOT" mark on the recovery tank.
CAUTION: Keep hand., toots and clothing -away from the engine COOling fa", to help prevent personIl intUry. lhiIlan is electric and can come on whether Or not the engine Is rUnning. 111. tan can start automatically In .respon .. to a heat sensor when the ignition Is in "Run."
Make sure the water pu"",, belts are not broken, or off the pulleys , and that the fan runs when the engine is running and there is an indication on the instrument panel of an overheat condition.
If the coolant level in the recovery tank is low, look for leaks at the radiator
hoses and connections, heater hoses and connections, radiator I and water pump. If you find major leaks, or spot other problems that may have caused
the engine to overheat,
do not run the engine untilthese problems have been
corrected. If you do not find a leak or other problem, caretully add coolant to
the recovery tank. (Coolant is a mixture of ethylene glycol antifreeze and water; see "Engine Cooling System" in "'Service and Maintenance," Section 5, for the proper antifreeze and mixture.) .
CAUTION: Under: some:' conditione, the ethylen~ glycol In engine coolant Is . combustible. -To help avoid being burned, DO NOT spill antifreeze or coolant on the exhauat system or hot engine parts..
If the coolant level in the recovery tank is at the correct level but there is still
an indication on the instrument panel of an overheat condition:
•
You may add coolant directly to the radiator. YOU MUST LET ENGINE COOL FIRST. See "Coolant Replacement" under "Engine Cooling
System"
in Section 5, "Service and Maintenance" in this manual. Follow steps t through 3 for the correct way to remove the radiator
cap
and add coolant.
Once the Engine Coolant Temperature light has gone out (or the Engine Coolant Temperature gage no longer signals an overheat condition), you can
resume
driving at a reduced speed. Return to normal driving after about ten
minutes If the light does not come back on (or the gage pointer does not again
show
ao overheat condition).
tf no cause for the overheat condition was found, see a qualified service technician.
JACKING
CAUTION
To help avoid personal injury:
• FollOW all jacking and stowage instructions .
• Use jack only for lifting this vehicle during wheel change.
• Never get beneath the vehicle, start or run engine while vehicle is
supported by jack.
• Always securely restow spare tire (or flat tire) and all jacking equipment.

case. To check, remove the dipstick on the driver's side of the case, above the
axle shaft, Be sure that the fluid level is at the "Full Cold" mark; oil may
appear on the bottom of the dipstick even when the fluid is several pints low.
I! needed, add enough lubricant to bring the fluid level up to the "Full Cold" mark on the dipstick. Be sure to fully seat the dipstick when reinstalling.
CLUTCH ADJUSTMENT
The clutch linkage in your vehicle should be adjusted every 5,000 miles (8 000
km) or less. To adjust the clutch linkage pull the clutch pedal up until it stops
and then depress the
pedal slowly.
NOTICE: To avoid clutch linkage damage do not continue to pull up on the pedal after
it stops.
Electric Fan
CAUTION: Keep hands, tools, and clothing away fr,om th~engine cooUng lanto help prevent personal injury. this fan is electric and can corne on whether or not the engine is
running. The fan can start automatically in response to a heat sensor when the ignition
key is in the "Run" position.
ENGINE COOLING SYSTEM
CAUTION: H your cooling system overheats, see "Engine Cooling System Overheating" in "In Case of Emergency," Section 3. CONTINUED OPERATION OFTHE ENGINE EVEN FOR A SHORT TIME MAY RESULT IN A FIRE AND THE POSSIBILITY OF
PERSONAL INJURY ANDIOR SEVERE VEHICLE DAMAGE.
Your vehicle has a coolant recovery.system. Coolant in the system expands with heat and overflows into the recovery tank. When the system cools down,
coolant is drawn back into the radiator.

Downloaded from www.Manualslib.com manuals search engine The cooting system was filled at the factory with a quality coolant that meets
GM Specifications.
~ is important to use proper coolant to prevent damage to
cooling system components . Coolants meeting GM Specification 1825-M or
those specially formulated for aluminum co"1JOflent protection should be used.
The cooling system is designed to use coolant (a mixture of ethylene glycol ,
corrosion inhibitors and water) rather than plain water. The coolant solution
must be used year round
to provide:
• freezing protection down to -37'C (-34'F),
• boiling protection up to 128 'C (262'F),
• protection against rust and corrosion in the cooling system,
• the proper engine temperature for efficient operation and emission control,
and
• proper operation of the coolant temperature light or gage .
See the Maintenance Schedule folder to find out when the coolant must be
replaced . Note that changing the coolant is needed
to make certain that all
parts
of the cooling system work well.
.-~~~~--~-.
CooUng System Care
Check the cooling system at regular intervals, such as during fuel sI the engine hood and look at the "see through" coolant recovery tank. When Ih8 engine is cold, the coolant level should be at or slightly above the "Full
Cold' .' mark on the recovery ' tank. When the engine has fully warmed up, the
level should be at or slightly above the "Full Hot" mark on the recovery tank.
H·the coolant level is low, remove the cap on the coolant recovery tank. Add to the recovery tank enough of a SO/ SO mixture 01 water and a good quality
eIIlyIene gIyool antifreeze (meeting GM SpecWication 1825-M) to bfing the level
"" to the proper mark. Pui the cap back on the recovery tank.
CAUTION: Under some' condttlons . the ethytene glycol In engine' coolant is combultlble. To help Rold being burMCf when adding eoollnt, DO NOT spill It on the exhliUlt system or engine ~rtI tMt mIIy be haL tf there It any question,' have this .....,ice performed by .• quallftecl t.chnlclan.
Certain conditions, such as air trapped in the system, may effect the coolant level in the radiator . You should check the coolant level in the radiator at the
time you change the engine 011 and when the engine Is cold. Follow the steps
under
"Adding Coolant" for the correct way to remove the radiator cap and add coolant.

Downloaded from www.Manualslib.com manuals search engine If you have to add coolant more than four times a year (either to the recovery
tank or to the radiator), or if
coolant is dirty or discolored, see your dealer for a cooling system check.
NOTICE: rr you use the proper quality antifreeze, there is no need to add extra inhibitors or additives which claim to improve the system. They may be harmful to the proper operation of the system.
Adding Coolant
CAUTION: To help avoid the danger of being burned, do not remove the radiator cap while the engine and radiator are stili hot. Scalding fluid and steam can be blown out under pressure if the cap is taken off too soon.
1. When the engine is cool, remove the radiator cap.
• Turn the cap slowly to the left until it reaches a "stop." Do not press
down
while turning the cap.
• Wait until any remaining pressure (indicated by a hissing sound) is relieved, then press down on the cap and continue turning it to the left.
2. Add enough water and ethylene glycol anmreeze (meeting GM Specification 1825-M) to provide the required cooling, freezing and
corrosion protection. Use a solution that is at least 50 percent antifreeze
but no more than 70 percent antHreeze. Fill the radiator to the base of the
filler neck and fill the coolahUocave,y lank to at or above the "Full Hot" mark. Put the recovery tank cap back on.
3. Run the engine, with the radiator cap removed, until the upper radiator
hose is
hot. With the engine idling, add coolant to the radiator until it
reaches
the bottom of the filler neck. Install the radiator cap, making sure
the arrows on the cap line up with the overflow tube on the radiator filler
neck.
II is Ihe owner's responsibility 10:
• Maintain cooling system freeze protection at -37°G (-34°F) to ensUre
protection against corrosion and loss of coolant from boiling. (A SO/SO mixture of water and ethylene glycol antifreeze will provide freeze
protection to -37°G or -34°F.) You should do this even if you don't
expect freezing temperatures. Periodic
replacement of coolant is needed to replace the anti-corrosion additives that wear out with use. Coolant that
has become dark in color shows that it needs to be changed for this reason.
• Add ethylene glycol base antifreeze that meets GM SpecHication 1825-M
when antifreeze has to be added because of coolant loss or for more
protection against freezing at temperatures less than stated.
NOTICE: Do not use methanol-base antifreeze, or alcohol, . or plain water alone, in your vehicle at anytime. They will boil ata lower point than that at which the "TEMP" light (or temperature gage) will warn of overheating, and they do not provide proper protection against corrosion.
Thermostat
The engine coolant temperature is controlled by a thermostat. It stops coolant
flow through the radiator until a preset temperature is reached. This thermostat
is installed in the engine coolant oullet on the engine block. The same
thermostat is used in both winter and summer. When a replacement is needed, AG-Oelco paris are recommended.

Downloaded from www.Manualslib.com manuals search engine • If the fluid is warmed up (about 66"C or 150"F -- hot to the touch), the
fluid level should be between the "HOT" and "Cold" marks on the power steering reservoir.
• If cool (about 21"C or 70"F), the fluid level should be between the "Add" and "Cold" marks.
This fluid does not need periodic changing.
FRONT SUSPENSION AND STEERING LINKAGE
Lubricate fillings at the interval shown in the Maintenance Schedule with water
resistant
EP Chassis Lubricant which meets GM Specification 6031M.
NOTICE: Ball joints should not be lubricated unless their temperature is -12"C (10"F), or-higher. During cold weather, they should be allowed to warm up as necessary before
being lubricated or damage to the ball jOint could occur.
FREEDOM BATTERY
Your new vehicle has a Delco FREEDOM battery. It needs no periodic
maintenance.
Its top is permanently sealed (except for two small vent holes) and has no filler caps. ,You will never have to add water.
The hydrometer (test indicator) in the top of the battery provides information for
testing purposes only.
If the vehicle is not going to be driven .f?r 30 days or longer, disconnect the cable from the "-" (black) negative terminal of the battery to prevent
discharge. For
full power needs at replacement time, a Del~o battery with the sarne catalog number as shown on the original battery'if . !abel " is recommended.
CAUTION: Follow the precautions listed in the "Jump Starting" Caution (see the "In Case of Emergency" section of this manual) when working on or near the battery. Personal injury (particularly to eyes) or property damage may result from battery explosion, battery acid, or electrical (Short circuit) burns.
AIR CONDITIONING
Periodically have your dealer check your air conditioning system to be sure
there has been no loss in cooling output. See your dealer immediately if you
suspect the system is not performing"as it should.
Your vehicle's air conditioning system will not operate below ambient
temperatures of approximately
4·C (40·F) regardless of control position.

Downloaded from www.Manualslib.com manuals search engine Wheel Replacement
Damaged wheels must be replaced. For example, replace wheels if they are
bent,
cracked,or heavily rusted, or if wheel nuts often become loose. Also
replace wheels which leak air (except some aluminum wheels which can be repaired-- see your authorized dealer). See the Caution under "Inspection and
Rotation"
in this section regarding the importance of obtaining good metal-to­metal contact when replacing or changing wheels.
Do not use bent wheels which have been straightened, and do not use inner
tubes in leaking wheels designed for tubeless tires. Such wheels may have
structural damage and could fail without warning. When replacing wheels for
any reason, the new wheels should be equal in load limit. diameter, width,
offset, and mounting configurations to those originally installed on your vehicle.
A wheel of the wrong size or type may adversely affect such things
as wheel
and bearing life, brake cooling, speedometer I odometer calibration, stopping
ability, headlight
aim, bumper height, vehicle ground clearance, and tire or tire
chain clearance to the body and chassis. Replacement with used wheels is not advised; they may have been treated harshly or have very high mileage, and
could fail without warning.
You can get wheels from your dealer.
Warranty
Tires are warranted by the tire manufa9turers. Warranty information is included
in the manufacturer's Warranty folder furnished With your vehicle.
