SERVICE AND MAINTENANCE
CAUTION: As with any machine, take care when making any check, doing any maintenance. or making any repair. t6ayoid being injured. Note that some of the materials in this vehicle may be hazardous if used, serviced, or handled improperly. Improper or incomplete serVice could also lead to the vehicle itself not working properly which may result in personal injury, or damage to the vehicle or its equipment. If you have any question about carrying out some service, have the service done by 8 skilled mechanic.
REPLACEMENT FASTENERS
During car maintenance, any fasteners used to replace older ones must have the
same measurements and strength as those removed, whether metric or customary. (The numbers on the heads of metric bolts and on the surfaces of metric nuts show
their strength. Customary bolts use radial lines to show this, while most customary
nuts
do not have strength markings.) Fasteners taken from the car should be saved
for re-use in the same spot when possible. Where a fastener cannot be used again,
take care to choose a replacement that matches the old one.
For information and help, see your Chevrolet dealer.
CAUTION: This vehicle is primarily dimensioned in the metric system, Most fasteners are i'neti'icand many lire vary closein dimension to well-known customary fasteners in the inch system. Mismatched or incorrect fasteners can result in damage to the car or possibly personal injury.
MAINTENANCE SCHEDULE
For owner convenience , a separate folder has been provided with your vehicle
which contains a complete maintenance schedule. It also briefly describes the
safety, emission control, lubrication and general service your vehicle requires.
The Maintenance Schedule folder is supplemented by this section of the Owner's
Manual, as well as a Warranty Information folder also furnished with your vehicle.
Read all three publications for a full understanding
of your vehicle's maintenance
needs.
You can get a replacement Maintenance Schedule from your dealer or send the VIN(or serial) number of your vehicle to Consumer Relations, Chevrolet Central
Office, Chevrolet Motor Division, Detroit, Michigan 48202.
Fuel Cap
The fuel tank filler cap has a "screw-on ratcheting type" feature. To·remove:
•
Rotate cap counterclockwise to clear the inside of the filler neck. This
will allow any residual pressure
to escape.
• To install, reverse this procedure and tighten cap securely until a "ratcheting", clicking sound is heard indicating cap is on properly.
NOTICE: If you need to replace the fuel cap, use only a cap with these same features as specified for your model. An incorrect fuel cap can result in a serious malfunction of the fuel system or emission control system. You can get a correct replacement cap from your dealer.

. The catalytic converter is an emission control device added to the
exhaust system to reduce exhaust gas pollutants. The converter
contains a ceramic material coated with noble metal catalysts. To prevent
contamination of the cata lysts,
unle~ded gasoline must be used. Unleaded gasoline
also reduc es combustion chamber deposits and exhaust system corrosion.
The catalytic converter requires the use of unleaded gasoline. Use
of leaded gasoline will cause the converter to lose its effectiveness for emission control. On some engines, the catalyst must be changed at cer tain inter vals in orde r for
the emissio n control system to continue to operat e properly. The change intervals
are speci fied in Section C of the Maintenance Schedule folder.
On cars that require this catalyst change, the word "EMISSION" will
appear on an indicator in the speedometer face at the specified change
in terval
s. This is a reminder that the cata lyst must be changed. (If the indicator does not appear, your car does not need this catalyst change).
Your Chevrolet deale r will perform the lirst cataly st cha nge at no charge, whether yO'u are the first owner or a subsequent owner. As part of this service, the indicator
should be reset to appear
at the next specified chang e interval. To help prevent
damage:
1. Keep your engine properly maintained. Engine malfunctions involving th e electrical, carburetion or ignition systems may result in unusually high
conve rter and exhaust system temperatures .
Do not keep driving your vehicle if you detect engine misfire. noticeable loss of
perform,8nce. or other unusual operating conditions. Instead, have it serviced promptly. A properly ···maintained engine will he lp avoid
malfunction s that could damage the converter.
It will also help provide good
emissio.n cq!).,trol and gasoline economy. See the Maintenance Schedule folder
for inform ation on inspecting a
nd maintaining the engi ne. exhaust system.
and other compone nts.
2 .
Do not drive through, idle, or park your vehicle over combustibl e materials,
s u ch as grass
or leaves. They could 'touch the hot exhaust system and ignite.
3. Do n o t push or tow this vehicle 10 stan it. This cou ld damage (he converter.
Disregarding this information could damage the catalytic converter, the vehicle,
or nearby property.
C-4 (COMPUTER CONTROLLED CATALYTIC CONVERTER)
SYSTEM If your new car was purchased in California, it has a special emission control
system, called
the C-4 (Computer Co ntrolled Catalytic Converter) System. The C4 System monitors the exhaust stream with an oxygen sensor. Based 4
on senso r signals, the electr onic control module adjusts the carburetor
air~fuel ratio as needed. It is very important to use only unleaded gasoline
in cars with
the C-4 System. Leaded gasoline will damage the oxygen
sensor. which may affect emission
control, fuel economy and drivability.
Some cars equipped with the C-4 System need an oxygen sensOr change
at the intervals specified in Section C of the Maintenance Schedule folder.
On these cars, an oxyge n sensor maintenance reminder is included in the
instrument paneL The word "EMISSIONS" is designed to appear in a
window in the speedometer face at the intervals outlined in the Maintenance
Schedule folder. The "EMISSIONS " indicator is a reminder that the oxygen
sensor must be repl aced with a new sensor.
Such replacement is necessary
in order to maintain the correct operation of the emiss ion control system.
The indicator must be reset as part of this service.

Downloaded from www.Manualslib.com manuals search engine NOTICE: You cannot read the correct fluid level if you have just driven the car for a long time at high speed, in city traffic in hot weather, or if the car has been pulling a trailer. Wait. until the fluid has cooled down (about 30 minutes).
Remove the dipstick located on the driver's side forward of the cowl. Carefully
touch the wet end of the dipstick to find out if the fluid is cool, warm or hot. Wipe
it clean and push it back in until the cap seats. Pull
out the dipstick and read the
fluid level.
• If it felt cool or warm (about room temperature), the level should be
between the dimples above the "Full" mark.
• If it was too hot to hold. the level should be at or in the hatched area.
Add just enough DEXRON-®n fluid to fill the transaxle. It takes only 0.5 liter
(one pint)to raise the level from "Add" to "Full" with a hot transaxle.
Do not overfill the transaxle. Overfilling can cause foaming and loss of fluid, which
could result in transaxle damage.
Automatic Transaxle Drain Intervals
Change the transmission fluid and change the filter (or clean the screen) as
outlined in Section
A of the Maintenance Schedule folder.
ELECTRIC FAN
CAUTION: Keep hands, tools, and clothing away from the angine cooling fan to help prevent personal injury. This fan is electric and can come on whether or not the engine is running. The fan can start automatically in response to a heat sensor when the ignition is in the "Run" position.
ENGINE COOLING SYSTEM
The coolant recovery system is standard. The coolant in the radiator expands with
heat, and the overflow collects in the recovery tank. When the system cools down,
the coolant
is drawn back into the radiator.
The cooling system was filled at the factory with a quality coolant that meets
GM Specification 1899-M. The cooling system is designed to use coolant (a mixture
of water and ethylene glycol antifreeze) rather than plain water. The coolant
solution should be used year round. It has many advantages, such as:
• provides freezing protection down to _37°C, (-34°P)
•
provides boiling protection up to 128QC, (262°P)
•
protects against rust and corrosion in the cooling system,
• maintains the proper engine temperature for efficient operation and emission
control, and
• allows proper operation of the coolant temperature light (or gage).
See Section A of the Maintenance Schedule folder to find out when the coolant
must
be replaced.
COOLING SYSTEM CARE
Check the cooling system at regular intervals, such as during fuel stops. You
usually do not need to remove the radiator cap to check the coolant level. Lift
the engine hood and look at the "see through" coolant recovery tank. When the
engine
is cold, the coolant level -should be at or slightly above the "Full Cold"
mark on the tank. When the engine has fully warmed up, the level should be at ')r slightly below the "Full Hot" mark on the tank. If the coolant level is low,

Power Steering System
Check the 'fluid level in the power steering pump at each engine oil change. Add GM :Power Steering Fluid, (Part Number GM 1050017) as needed:
, • Ifnuid is warmed up (abo ut 66°C or lSO"F --hot to the to uch), the fluid level
should be between the "Hot" and "Cold" marks on the filler cap indicat or.
• 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.
Freedom Battery
Your new vehicle has a Delco FREEDOM battery. It needs no periodic
maint enance . Its
lOp is permanently sealed (except for two small vent holes) and
has no filler caps. You will never have to add water. .
The hydrometer (test indicat or) in the top of the battery provides information for
testing purposes only.
For full power needs at repla cement time, a Delco battery with ,the same catalog
number as shown on the original banery's label
is recommended.
CAUTION: FoUow the precautions listed in the Jump Starting Cautton {see the "'n Case of Emergency''' section o"f 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 electric.1 (short circuit) burns.

7 .
If an air loss occurs while driving. do not drive on the flat tire more than
is needed to stop safely . Driving even a short distance _on a flat tire can damage
a tire and wheel beyond repair.
Inspection and Rotation
Front and rear tires perform different jobs and can wear differently depending
on the types
of roads driven, your driving habits, etc.
For longer tire life, you should inspect and rotate your tires as recommended in
Section A
of the Maintenance Schedule folder. Many car and tire dealers will perform -a free lire inspection to look for uneven or abnormal tire wear (usually
the result of wrong inflation pressures, lack of regular rotation, improper wheel
alignment, tires out
of balance, or poor driving habits).
After rotation, adjust the front and rear tire pressures (see
"Tire Placard") and be sure to check wheel nut tightness. (Wheel nulS should also be tightened at
certain intervals ; see the
hIn Case of Emergency" section, page 3-6, for further
information.)

Alignment and B.alance
Proper wheel alignment improves tire tread mileage . Your vehicle's suspension
. parts should be inspected often and aligned when needed. (See the Maintenance
Schedule Folder for m ore information.) Ball joints have built-in wear indicators,
and some movem ent in th~ joint s is normal. ' Improper alignment will not cause
the
vehicle to vibrate. However, improper toe alignment will cause the tires to roll
at an angle which will result in faster tire wear. Incorrect caster or camber
alignment will cause your tires to wear unevenly, and can cause the vehicle to
"pull" to the left or right.
Proper tire balan cing provides the best riding comfort and helps reduce tire tread
wear. Out--of-balan ce tires -can .cause annoying vibration and uneven tire wear such
as cupping and
flat spots.
Traction
A decrease in driving. cornerin g, and braking traction occurs when water, snow,
ice, gravel ,
or other material is on the road. Driving practices and vehicle speed
should be adjusted to the road condition~.
When driving on wet or slushy roads, a wedge -of water can build up between the
tire and road. This is known as hydroplaning, and may cause partial or complete
l oss
of traction, vehicle control, and stopping ability.
To reduce the chance of traction loss, follow these tips:
I. Slow down during rainstorms or when roads are Slu shy .
2. Slow down if road has standing water or-pUddles.
3. Replace tires when tread wear indicators are showing.
4 . Keep tires properly inflated.
If your vehicle has TPC radial.tires (see "Tire Replacement" in this section), your
lir es were design ed to
provide _ better snow tracti on than -bias or bias-belled tires
without snow treads. However , iF . yo u use conventional snow tires. be sure they
are the same size. loa d range, and construction type (bias, bias belted,
or radial)
as your other tire
s.
