1984 CHEVROLET CAVALIER air condition

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

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).

Downloaded from www.Manualslib.com manuals search engine • Install the chains on the front tires as tightly as possible, then tighten them
again after driving 1/4 to 1/2 mile (0.4 to 0.8 kilometer). The use of chains
on the rear tires is not recommended; the chains may contact and
possibly damage the vehicle. If you intend to use chains on the rear tires, be sure
there is enough clearance.
• Do not exceed 45 mph (70 km/h), or the chain manufacturer's speed limitation, if lower.
• Drive in a restrained manner and avoid large bumps, potholes, severe turns and other manuevers which CQuid cause the tires to bounce up and down.
• Follow any other instructions of the chain manufacturer which do not
disagree with the above.
Spare Tire
For the use and installation of your spare tire, see "In Case of Emergency,"
Section 3 of this manual.
Tire Replacement
CAUTION:" 00 not mix different tire construction types (such as radial, bias, and bias­betted) on your vehicle exceptio emergencies, because your vehicle's handling could be affected and may result in loss Of control. This caution does not apply to a compact spare tire furnished with your vehicle.
On most vehicles originally eqUipped with radial tires, you will find a TPC Spec.
No. (Tire Performance Criteria Specification Number)
molded into the tire
sidewall
near the tire size marking. This shows that the tire meets rigid size
and performance standards which were developed for your vehicle. The TPC
Spec. No. assures a proper combination of endurance,
handHng, load capacity,
ride and traction on wet, dry, or snow-covered surfaces. When you replace your tires with tires having the same TPC Spec. No., your new tires will be
compatible with your vehicle.
When replacing tires with those not having a TPC Spec. No., you should use
the same size, load range, and construction type (bias, bias-belted, or radial)
as the original tires on your vehicle. A different size or type of tire may affect
such things as ride, handling, speedometer/odometer calibration, vehicle
ground clearance, and tire or tire chain clearance to the body or chassis. If
replacing only a single tire, it should be paired on the same axle with the least worn tire of the other three.
Uniform Tire Quality Grading
The following information relates to the tire grading system developed by the
United States
National Highway Traffic Safety Administration which will grade
tires by traction and temperature performance. (This applies only to vehicles
sold in the United States.)
Traction -A, B, C
The traction grades, from highest to lowest are: A, S, and C. They represent
the tire's
::ability to stop on wet pavement as measured under controlled
conditions on specified government test
~urfaces of asphalt and concrete. A
tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based on braking (straight­
ahead) traction tests
and does not include cornering (turning) traction.
5-16

Downloaded from www.Manualslib.com manuals search engine ,
Temperature -A, B, C
The temperature grades are A (the highest), B, and C, representing the tire's
resistance 10 the generation of heat and its ability 10 dissipate heat when tested
under controlled conditions on a specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate
and reduce tire life, and excessive temperature can lead to sudden tire failure .
The grade
C corresponds 10 a level of performance which all passenger car
tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory lest
wheel than the ",nimum required by law.
Warning : The temperature grade forlhis tire is established for a tire that is properly inflated and not overloaded . . Excessive speed, underinflation, or
excessive loading, either separately or in combination , can cause heal buildup and possible tire failure .
These grades are molded on the sidewalls 01 passenger car tires.
While
the tires available as 'standard or optional equipment .on General
Motors vehicles may vary with respect to these grades, all such tires meet General Motors performance s!andards and have been approved for
use on General Motors vehicles. All passenger car tires must conform to Federal safety requirements in addition to these grades.
You
should replace your tires when:
1 . The tires are worn to a point where 1.6
milHmeters (2/ 32 inch) or less t.read remains, or the cord or fabric is showing. '.
To help you detect this, your tires have built-in tread wear indicators that
appear between the tread grooves when the tread is 1.6 millimeters
(2/32
inch) or less. When the indicators appear in two or more adjacent grooves at
three spots around the tire, the tire should be replaced.
