REGARDING
CHEMICAL
PAINT SPOTTING
ChevTOlet believes that certain we_ather and atmospheric condi­
tions may create a chemica l fallout whereby certain airborne
pollutants
fall upon and attack vehicle paints. Occurren ces have
taken place primarily in the northeast ern-seaboard area. The paint _damage -takes two forms: -Blotchy . ringl et shaped discolora­
tions , and small irregula r dark spots etched into the paint surface.
Paint
spotting as a result of the fallout is not re lated to a defect
in paint material s or workmanship. For this reason, claims arising
from this condition are not co nsidered to be 'warranty related.
Nevertheless, because Chevrolet shares the pride which our owners take in preserving and maintaining the appearance of their vehicles, Chevrol et has authorized its dealers to repair, at no charge [Q the owner, the surfaces of new ve hicl es damaged
by this · faDout condition within 12 . months or 12 ,000 miles of purchase, whichever comes first .

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.

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 On all C-4 cars, a "CHECK ENGINE" light on the instrument panel is
designed to come on during engine starting , to let you know the bulb is working. (The light will stay on a short time after the engine starts.) If the light comes on while driving, service to the emission control system
may be required. See your Chevrolet dealer' as soon as possible for an inspection of the system. Continued driving without having the C-4 System serviced _ could eventually
cause damage
to the emission control system . It could also affect fuel
e conomy and drivabili -ty.
ENGINE OIL AND FILTER RECOMMENDATIONS • Engine oils' are labeled on 'the containers with various API (American
Petroleum Institute) designations 6f quality. Use engine oils that are labeled
5E or SE/CC. Do not use oils labeled only SA, 5B, 5C, SD, CA, CB, CC or CD; _or oils with the combination label SE and CD (SE/CD). Higher
quality oils labeled SF will be introduced soon (late 1979, or 1980). These SF oils are preferred and should be used when available.
• The oil and filter change intervals for your engine are based on the use of SE-quality or SF-quality oils and ,high- quality filters such as AC oil filters. Using oils other than SE-quality or SF-quality oils, or oil change intervals
longer than recommended. could reduce -engine life and might affect your
warranty.
• Your engine was filled with a high·quality engine oil when it was built. You do ,not have to change this oil before the suggested change period.
•
If your normal driving does nQt include one or more of the four "severe service" conditions listed below. change the oil every 7,500 miles (12 000 ' kilometers) or 12 months, whichever comes first. Change the oillilter at the
first oil change. then every second oil change, if mileage (7,500 miles or 12
000. kilom~ters) determines .w ,hen you change the oil. If _time (12 months)
determines when you change the oil, change the filter with every oil change.
• Change the oil and oil filter every 3,000 miles (4 800 kilometers) , or three
months if you often drive under one or more of these 'severe service·,~.
conditions: • Driving in dusty areas
• Towing ,3 trailer
• Frequent idling or idling for long periods
• Driving 4 miles (6 kilometers) br'less in freezing weather,o~other short trips in cold weather, where the engine does not thoTough ,ly warm up.
• Change the oil and oil filter as soon as -possible after driving in a dust
storm.
Oil Viscosity
Engine oil viscosity (thickness) has an effect on fuel economy. Lowec viscosity
engine oils can provide increased , fuel " economy; however, higher temperature
weather conditions require higher viscosity engine oils for satisf~ctory lubrication.
To. get the best fuel economy with your-1980 Chevrolet, -iou should use -,, ' .
fuel. 'saviiJ.&:_engine oil ohhe_ proper viscosity. These oils call_ be found. in serviCe
stations and other retail stores. They are-identified by words such as: "Energy Saving," "Conserves Gasoline," "Gas Saving," "Gasoline Saving," '''Friction
Reducing," "Improved Gasoline Mileage" or "Fuel Saving."
The following chart lists the engine ' oil viscosities recommended for the
temperature range you expect before the next oil change. For lemperalures above ,_18°C (O"F),SAE lOW-30 is -the preferred viscosity grade. Ircold-weather starting
problems
are encountered at temperatures below -lSoC ( oils may be required.

the oil level at regular intervals (such as every 'o ther fuel stop) and keep it above
th e "Add" line. Rem ember, your engine may use more oil when it is new .
• The best time to check the engine oil level is when the oil is warm, such as
during a fuel stop. First, wait about 5 minutes for the oil to drain back to
the oil pan, Then, pull out the dipstick, wipe
it clean, and push it back down
all the way . Now , pull out.th e dipstick and look at the oil-level on the dipstick.
Some
dipSlicks have "Add" and "Full" lines , Others are marked "Add! Qt" ­
and "Operaling Range." In all cases, keep the oil level above the
"Add" line. Push· the dipstick back down all the way after taking the
reading. _ A ·dd oil , if needed.
• If you check the oil level when the oil is cold, do no t run the engine first. The cold oil wilJ not drain back to the pan fast enough to give a true oil level.
Engine Oil Additives
There are many extra engine oil additives (or helpers) for sale. Your engine should
not need these extra additives if you use SE-quality or SF·quality engine oil and
change
it as suggested. If you think your engine has .an oil-related problem, talk
to your authorized dealer.
If needed, your dealer can provide you with a tested
and approved oil additive called "GM Engine Oil Supplement."
AUTOMATIC TRANSAXLE FLUID RECOMMENDATIONS
Use the Proper Fluid Use only automatic transmission fluid labe led DEXRON-®II. You can buy this
fluid from your Chevrolet dealer or
othe~,'service outlets.
Check the Fluid Level with care Check the automatic transmission fluid level at each engine oil change. Before
checking the fluid level, set the parking brake and then start the engine. AppJy
the regular brakes and then
'mov e the shift lever through all of the gear ranges,
ending in
"P '·(Park). You must check the fluid level with the engine funning at
slow idle and the car level.

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,

may be speeded by removing the drain plugs in the block.)
4. Close the drain valve (install block drain plugs, if removed). Add water until
the system is filled and run the engine until the upper radiator hose is hot again.
5. Repeat steps 3 and 4 several times until the drained liquid is nearly colorless.
6. Drain the system and then close the radiator drain valve tightly. (Install block
drain plugs, if removed.)
7. Disconnect all hoses from the coolant recovery tank. Remove the tank and
pour out any fluid. Scrub and clean the inside of the tank with soap and water.
Flush it well with clean water,
then drain it. Reinstall the tank and hoses.
8. Add enough water and ethylene glycol antifreeze (meeting GM Specification
1899-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 antifreeze. Fill the radiator to the base of the filler neck and fill the
coolant recovery
tank to the "Full Hot" mark. Put the recovery tank cap back
on.
9. Run the engine, with the radiator cap removed, until the upper radiator hose
is hot.
10. 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.
It is the owner's responsibility to:
• Maintain cooling system freeze protection at _37°C (_34°F) to ensure
protection against corrosion and loss of coolant from boiling. (A SO/50
mixture of water and ethylene glycol antifreeze will provide freeze protection
to ~ 37°C ore -34°P.) You should do this even if you don't expect freezing
temperatures.
• Add ethylene glycol base antifreeze that meets GM Specification 1899-M
when antifreeze
hasto be added because of coolant loss or for more protection
' against freezing at temperatures lower than _37°C (-·J4°P).
NOTICE: Do not use alcohol or methanol-base antifreeze. or plain water alone. in your vehicle at any time. They will boil at a lower pOint than that at which the hot light indicator (or temperature gage) works. and they do not provide proper protection against corrosion.
Radiator Pressure Cap
The radiator cap, a 105 kPa(15 psi) pressure type, must be installed tightly,
otherwise coolant may be lost and damage to engine may result from overheating.
Radiator pressure caps should be checked periodically for proper operation.
If
replacement is required, an AC cap is recommended.
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 outlet on the engine block. The same thermostat is used in both winter and summer. When a replacement is needed, AC~Delco parts
are recommended.
