be performed on your ca r. One of two type s' o f se rvice is required :
• On cars equipped with the C-4 System, the oxygen sensor must be replaced with · a new sensor, or
• On
ca rs without the C -4 System, the cataly st in the catalyti c converter must
b e c han ged.
In either case, see yo ur Chl!~rolet dealer fo r se rvice when the "EMISSIONS "
indicat or appears. .

Downloaded from www.Manualslib.com manuals search engine Engine Temperature Gage
This gage indicat~cCX?lant temperature which will vary with air temperature and
operating condition~, The ignition must be on for accurate readings. Hard driving
or prolonged idling In very hot weather will cause the pointer to move beyond the center of the band; Should pointer move to the Red Zone, see "Engine Cooling
System" on page 3-3.
Oil Pressure Gage
The oil pressure gage indicates the pn;ssure at which oil is being delivered 10 the various parts of the engine requiring lubrication. Pressures registered by the gage
I11.!lY vary according to outside air temperatures or weight of oil being used. Oil
pressure of a cold engine ~ing operated at a given speed will be somewhat higher
than when the engine is at normal operating temperature at the same speed .
. Prolonged high speed operation on a hot day at the given speed will result in somewhat lower oil pressure readings. Readings of 30 to 40 psi (205 to 275 kPa)
mny
be considered normal during moderate road speeds of 35 to 40 mph (55 to
60 km/h) \\lith the engine at proper operating temperature. Gage readings which
are
consistently high or Im\l under these conditions may indicate lubrication system Voltmeter
When the engine is operating, the voltmeter indicates the electrical system voltage.
During minimum electrical load, the pointer will read to the right of the center.
As the electrical load is increased,
or in stop-and-go driving, the pointer will rotate
to the left. A meter reading continuously in
the left or right red zone indicates
an electrical system
failure .. Cause of the failure should be determined and corrected~
Light Switch
The three position light switch controls the headlights, taillights, parking lights,
sidemarker lights, instrument lights and dome lights as shown. The headlamp
circuit is protected by a circuit breaker in
the light switch. An overload on the
breaker will cause the lamps to "flicker" on and off. If this condition develops,
have your headlamp wiring checked immediately.
The headlight beam changer is located. in the
Turn Signal Lever; for operation

The filler panel or cargo cover, between the rear 88atback and the rear window should not be used to carry objects-even those that are small and light. All nems should be secured in place. This will help keep such things from being thrown about and Injurying people in the car during an accident. Cargo weight whether inside or on the roof, should be positioned as evenly as possible from front to rear.
ROOF LUGGAGE CARRIER
The optional roof luggage carrier is designed to allow loading of items onto the
roof
of your car. The roof luggage carrier does not increase the total load carrying
capacity of th e car , as shown opposite "Max Load" on the Tire Placard located
on the left front door. Be sure the total weight of the cargo on the roof, plus the
weight
of the cargo and passe ngers inside the car, plus the tongue load of any
trailer you are towing does
,1;10t exc_eed this "Max Load" vehicle capacity weight. See Section 5, page "5-11 for more information on Vehicle Loading . Also see the
infonnation on Trailer Towing
in Section 1 of this manual . if needed .
NOTICE:To helpayoid pOSSible damage, do not exceed 70 kilograms (1 50 pounds), cargo weight on the roof. Position the cargo in the luggage carrier as evenly as: pOssible. If carrying long items, never exceed car length and fasten such loads securely at the front and rear of the car, as well as to the luggage rack.
The roof luggage carrier consists of: five roof slats bolted to the top of the car,
two crossrails with knobs at each end th~t allow the crossrails to be adjusted or removed, and six' adjustable tie-downs.
The operation
of each item is as follows: the crossrails are easily adjusted forward
or rearward in order to help position your load. To move the crossrails , rotate
the large adjustable knob, ··No. 3" in the figure above. counterclockwise to loosen
(or remove) the crossrails and 'clockwise to tighten down the cros srails. Attached
to the top
of the crossrails are two adjustable tie-downs, "No.4" in the figure.
Ther e is also one adjustable lie-down located in the center of each outer roof slat
assembly (also called
"No.4" in the figure) . The tie-downs may be easily moved
forward and rearward within the outer slat assembly and across the top
of the
crossrails to the desired position.
To move the tie-down . rotate it countetclockwise
to loosen and clockwise to tighten down. If needed to sec ure a certain type of lead,
the tie-downs on the
crossratls may be removed and repos itioned on the outer roof
slat assemblies. While underway, periodically check to make sure that
the crossrails and the tie-downs are securely fastened to help
prevent loss of cargo, or the roof rack equipment itself.
The crossrails may be removed when not in use and stowed in the trunk or behind

or electric sparks. Also do not smoke near a ,battery. Batteries give off a gas which is flammable and explosive.
• To lessen the risk of injury incase an explosion does occur, wear eye protection or shield your eyes when working near any battery. Do not lean over a battery.
• Do not allow battery fluid to contact eyes, skin, fabrics, or painted surfaces
because battery fluid is a corrOsiVe acid. Flush any contacted area with water immediately a,nd thoroughly. Also get medical help if eyes are affected.
• To lessen the riskofa short circuit. remove rings, metal watch bands and otl:ler metal jewelry. Also do not allow metal tools to contact at the same time the positive battery terminal (or any metal connected to this terminal) and any other metal em either "ehicle. Make certain when attaching the jumper cable clamps rothe positive terminals of the batteries that neither clamp contacts any other metal.
• This
vehicle has a 12 volt battery and a negative ground electrical system. Make sure that the other vehicle als~ has a 12 volt battery and that the negative terminal, is .'grounc::ted(attached to a metal, part of the vehicle). Its owner's manual may give you that information, If unsure of the other vehicle's voltage (or if the voltage and/or ground on the other vehicle are different from your vehicle). do not try to jump startas personal injury or severe damage to electrical and electronic parts may result.
• If the discharged battery has filler caps. check the fluid level. ( 00 not check with an Op~tn flame and db not smoke .) Add clear drinking water to the proper level if low, and replace the caps before jump starting.
I. Position, the vehicle with'the good (charged)ba,.ttery so that the jump starting
cables will reach.
Do not let the vehicles t"ouch.
2. Turn off all electric motors and accessories in both vehicles. Turn off all lights
except those needed to protect the vehicles or light up the work area. Turn
off the ignition, apply the parking brake firmly, and shift the automatic transaxleto "p"o.?ark) (manual transaxle to "N"(Neutral) in both vE-hicles.
3. Jumper Cable Connection Instructions (See illustration) .
• Connect the first jumper cable from the positive" +" (red) terininal on
one battery to the positive "+" (red) terminal on the other battery.
Never, connect "+" (red) to "~" (black), or '\" to "+".
• Next, connect one end of the second cable to the grounded negative "."
(black) tenninal of the good (charged) battery.
• Lastly, connect the othetend of the second jumper cable to a solid,
stationary, metallic point on the engine of the vehicle with the discharged
battery but at a
point away from the battery --450 millimeters (18 '1
inches) or more from the battery if possible. Do not connect it to or attach it near pulleys, fans, or other parts that will move wHen the engine
is started. Don't touctt hot manifolds as they _can cause severe burns. If hot or moving parts can be avoided, the MOUNTING BRACKETS for
the Delcotron generator,
or the air conditioner compressor, ,generally
make a good point for-this final ground attachment. Take care that the
jtimper cable does
hot contact moving parts on or near the generator
or compressor.)
4. Start the engine of the vehicle with the good (charged) battery and run the
engine at a moderate speed.

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.

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,
