SERVICE AND MAINTENANCE
Your authorized dealer has factory trained technicians and Genuine GM Parts
to service your vehicle properly_ For expert advice and quality service, see your authorized dealer.
CAUTION: As with any machine, take care when making any check, doing any maintenance, or making any repair, to avoid being injured. Some of the MATERIALS in this vehicle may also be hazardous if used, serviced, or handled improperly. Improper or incomplete service can affect the vehicle itself which may in turn result in personal
injury, or damage to the vehicle or its equipment. H you have ANY question about carrying out some service, have the work done by a skilled technician.
REPLACEMENT FASTENERS
During vehicle 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 rnetric bons 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 vehicle 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
authorized dealer.
CAUTION: This vehicle is primarily dimensioned In the metric system. Most fasteners
are metric and many are very close in dimension to well· known customary fasteners in the inch system. Mismatched or incorrect fasteners can result in damage to the vehicle or possibly personal injury.
MAINTENANCE SCHEDULE
For owner convenience, a separate folder ,has. bee" providef;1 with your vehicle which outlines the maintenance your vehicle requires. The Maintenance
Schedule folder is supplemented by this section of the Owner's Manual.
Read this publication for a full understanding of your vehicle's maintenance
needs.
If you need a replacement Maintenance Schedule, see your dealer or contact the . Consumer . Aelations Representative, . Chevrolet Central Office,
Chevrolet Motor Division, Warren, MichigarL4809ll-13t~2-550Q1 (In Canada, contact the Customer Services Representative, General MotorsoT---­
Canada LId., Oshawa, Ontario, L1J 5Z6; 416/644-6624).
FUEL CAP
The fuel cap is located behind a hinged door on the right'rear fender. For your
convenience there
is a fuel cap hanger located on the filler door.
The
fuel tank filler cap has a "s£rew-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.

Downloaded from www.Manualslib.com manuals search engine NOTICE: H you need to replace the fuel cap, use only a cap specified for your model. An incorrect fuel cap can result in a serious maHunction of the fuel system or emission control system. You can get a correct replacement cap from your dealer.
CATALYTIC CONVERTER
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
and loss of effectiveness of the catalysts. unleaded gasoline must be used.
Unleaded
gasoline also reduces spark plug fouling, exhaust system corrosion and engine oil deterioration. Leaded gasoline will also damage the oxygen
sensor
in the Computer Command Control system which could affect emission
control.
To help prevent damage:
1. Keep your engine properly maintained. Engine malfunctions involving the
electrical, carburetion, electronic fuel injection or ignition systems may
result in unusually high catalytic converter and exhaust system
temperatures which, under extreme malfunctioning conditions, may ignite
interior floor ·covering materials above the converter. Do not keep driving
your vehicle if you detect engine misfire, noticeable loss of
performance, or other unusual operating conditions. Instead, have it
serviced promptly. See the Maintenance Schedule folder for information on inspecting and maintaining the engine, exhaust system, and other
components.
2. Do not push or tow this vehicle to start it. This may result in unusually
high catalytic converter
and exhaust system temperatures which under
extreme conditions may ignite interior floor-covering material above the
converter.
Disregarding these instructions
could damage the catalytic converter, the vehicle, or nearby property and affect warranty coverage.
COMPUTER COMMAND CONTROL SYSTEM
Most vehicles sold in the United States (and some vehicles sold in Canada)
have the Computer Command Control system.
The Computer Command Control system monitors the exhaust stream with
an oxygen sensor. Based on sensor signals, the electronic control module adjusts
the air-fuel ratio
as needed. It is very important to use only unleaded
gasoline in vehicles equipped with the Computer Command Control system.
Leaded gasoline will damage the oxygen sensor,
and may affect emission
control.
"Check Engine" Light
Most vehicles sold in the United States (and some vehicles sold in Canada)
have the Computer Command Control system.
Vehicles
.with the Computer Command Control system, include a "CHECK
ENGINE" light
on the instrument panel designed to indicate the need for
system service. It will come on during engine starting to let you know the bulb
is working. (The
light will stay on a short time aiter the engine starts.) Have the
system repaired if the "CHECK ENGINE" light does not come on during engine
starting.
If the light comes on, either intermittently or continuously while driving,
service to the Computer Command Control system is required. Although in
5-2

Downloaded from www.Manualslib.com manuals search engine most cases the vehicle is drivable, and does not require towing, see your
authorized dealer as soon as possible for service of the system.
Continued
driving without having the Computer Command Control system serviced could eventually cause damage to the emission control system. It
could
also affect fuel economy and drivability .
ENGINE OIL AND FILTER RECOMMENDATIONS
The following engine oil recommendations are based upon the operation . of your engine with the fuels recommended under "Fuel Requirements" in Section 2 of this manual.
Checking Oil Level
The engine oil must be kepi at the right level to help assure proper lubrication
of your vehicle's engine. n Is normal for an engine to use some oil, and some
engines may use more oil when they are new.
It is the owner's responsibility to check the oil level at regular intervals (such as every fuel stop), accorcing to the following instructions:
• The best time to check the engine oil level is when the oil is warm, ~h as
during a fuel stop. After stopping the engine, wait a few minutes for the oil
to drain back to the oil pan. Then, pull out the dipstick on the front of the
engine. Wipe it clean, and push the dipstick back down
all the way. Now, pull out the dipstick and look at the oil level on It. '
Add 011, If needed, to keep the 011 level above the "ADD" line, Avoid
overfilUng
the engine since this may cause engine damage. Push the cipstlck
back down all the way after taking the reading.
• n you check the oil level when the oil is cold, do not run the engine first.
The
cold oil will. not drain back to the pan fast enough to give a true oil
level.
Choosing the Right Quality Oil
Engine oils are labeled on the containers with various APi (American Petroleum
Institute) designations of quality. Be sure the oil you use has the API
designation "SF," either alone or shown with other designations such as SFI CC or SF ICD. These designations may be separated by commas. slashes or dashes. Oils which are not labeled "SF " should not be used. For example , do
not use oils labeled ONLY SA, sa, SC, SO, SE, CA, ca, CC, or CD; or .oils with a combination of any of these letters-such as "SE/CD" as this
may cause engine damage.

Downloaded from www.Manualslib.com manuals search engine Choosing Oil Viscosity
Engine oil viscosity (thickness) has an effect on fuel economy. Lower viscosity
engine oils can provide better fuel economy; however, higher temperature
weather conditions require higher viscosity engine oils for satisfactory
lubrication.
Using oils of any viscosity other than those viscosities
recommended
could result in engine damage.
When choosing an oil, consider the range of temperature your Vehicle will be
operated in before the next oil change. Then, select the recommended oil viscosity from the following chart. If outside temperatures are not expected to
exceed
38°C (100°F) prior to your next oil change, SF-quality, SAE 5W-30
Energy-Conserving engine oil is the preferred viscosity grade.
FOR BEST FUEL ECONOMY AND COLD STARTING, SELECT THE LOWEST SAE VISCOSITY GRADE OIL FOR THE EXPECTED TEMPERATURE RANGE.

Energy Conserving Oils
It is recommended that you select an oil not only of the proper quality and
viscosity, but also a fuel-saving product. These oils can be found in dealer
service departments, service stations and other retail stores. They are
identified
by words such as: "Energy Conserving," "Energy Saving,"
"Conserves Gasoline,"
"Gas Saving," "Gasoline Saving," "Friction
Reducing," "Improved Gasoline Mileage," "Improved Fuel Economy" Or "Fuel
Saving."

Downloaded from www.Manualslib.com manuals search engine Oil Identification Logo
A logo (symbol) has been developed to help you select the oil you should use,
and it probably will be included on oil cans sometime during 1983. The top
portion of the logo shows the oil quality by API designations such as SF, SFI
CC, or others. The center portion of the logo will probably show the SAE
viscosity grade, such as SAE 5W-30. "Energy Conserving," shown in the lower portion, indicates that the oil has fuel-saving capabilities.
Change Intervals
The oil and oil filter change intervals for your engine are based on the use of
SF-quality oils and high-quality fi~ers such as AC oil filters. Using oil other
than SF-quality, or oil and filter change intervals longer than
recommended could reduce engine life. Damage to engines due to improper
maintenance or use of incorrect
oil quality and/ or viscosity is not covered by
the Chevrolet new car warranties.
Your engine was
filled with a high-quality engine oil when it was built. You do
not have to change this oil before the first recommended change interval.
Oil
and filter change intervals depend upon how you use your vehicle. The
following should assist in determining the proper oil and fi~er change intervals:
TVPEOFUSE CHANGE INTERVAL
• Operating
in dusty areas.
• Towing a trailer.
• Idling for extended periods andlor low speed operation such as found • Change engine oil and filter every
in police, taxi or door-Ie-door de-livery service. 3,000 miles (4 800 kilometers) or 3
rn.onths, whichever comes first.
• Operating when outside tempera-tures-remain below freezing and when most trips are less than 4 miles' (6 kilometers)~
• Operating on a daily basis, as a • Chan:ge engine oil every 7,500 general rule, for several miles and miles (12 000-km) or 12 months,
when none of the above conditions whichev.er comes first. Change en·
apply. gine oil filter at first oil change. then every other oil change if mileage determines· when you change oil. If time determines change intervals, change the filter with each oil change.
Engine Oil Additives
Engine oils contain a variety of additives. Your engine should not need any
extra additives
K you use the recommended oil quality and change intervals. However, H you think your engine has an oil-related problem, a supplemental
additive ("GM Engine Oil Supplement") is available that may solve your problem without causing other difficuHies. Consu~ your dealer who can provide
you
w~h this tested and approved additive.
Used Oil Disposal
Do not dispose of used engine oil (or any other oil) in a careless manner such
as pouring it on the ground, into sewers, or into streams or bodies of water.
Instead, recycle it by taking it to a used oiL collection facility which may be
found
in your area. If you have a problem disposing of your used oil, it is
suggested that you contact your
dealer or a service station.

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.

Inflation Pressure
The cold inflation pressures listed on the Tire Placard provide forAIlebest
balance of fuel economy, tire life, riding comfort, and vehicle handling under normal driving conditions. These pressures should be used for all vehicle
loading conditions.
Incorrect tire inflation pressures can have adverse effects on tire life
and vehicle performance. Too Iowan air pressure causes increased tire flexing and
heat buildup. This weakens the tire and increases the chance of damage or
failure. It can result in tire overloading, abnormal tire wear, adverse vehicle handling, and reduced fuel economy. Too high an air pressure can result in
abnormal wear, harsh ride, and can increase the chance of damage from road
hazards.
Check tire inflation pressures at
least monthly (this includes the spare tire) and
whenever your vehicle is serviced. When possible, check tire inflation
pressures
when the tires are "cold."
1. The "cold" tire inflation pressure is the tire pressure when a vehicle has
not been driven more than one mile (1.6 kilometers) after sitting for three
hours or
more. This is the most accurate pressure reading.
2. .It is normal for tire pressures to increase 30 to 60 kilopascals (4 to 8 pounds per square inch) or more when the tires become hot from driving.
If you must set inflation pressures when the tires are not "cold," set them
28 kilopascals (4 pounds per square inch) more than'the cold pressures
recommended on the Tire Placard.
3. The· tire inflation pressures on the Tire Placard are adequate for all speeds. No tire pressure adjustment is required for freeway speeds. (Also
follow
the Caution at the beginning of this "Tire" section).
