1984 CHEVROLET CAVALIER service

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 AUTOMATIC TRANSAXLE FLUID RECOMMENDATIONS
Use the Proper Fluid
Use only automatic transmission fluid labeled DEXRON'" II. You can buy this
fluid from your dealer or other service outlets.
Check the Fluid Level with Care
Check the automatic transaxle fluid level at each engine oil change. Driving
with too much or too
little fluid can damage the transaxle.
To check the fluid
level, first set the parking brake, then start the engine in
"P"(Park), and let idle for two minutes . You must check the fluid level with the
engine running at slow
idle and the vehicle level.
You cannot read the correct fluid level if you have just driven the vehicle for a
long time at high speed, in city traffic in hot weather, or if the vehicle 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 roomternperature and warmer, but not too hot
to hold), the level should be between the two dimples above the "FULL"
mark.
• If it was too hot to hold, the level should be in the cross-hatched area on the dipstick, near the "FULL" mark.
Add just enough DEXRON'" II 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.
Automatic Transaxle Drain Intervals
Change the transaxle fluid and change the filter as outlined in the Maintenance Schedule folder.
MANUAL TRANSAXLE
See the Maintenance Schedule folder to find out how often the fluid level should be checked and what type of lubricant should be used.

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).
