check engine CHEVROLET CAVALIER 1997 3.G Repair Manual

Downloaded from www.Manualslib.com manuals search engine When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be at
60 psi (420 Pa).
How to Check
Use a good quality pocket-type gage to check tire
pressure.
You can’t tell if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks by keeping out dirt
and moisture.
Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10
000 to 13 000 km). Any time you notice unusual
wear, rotate your tires as soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See “When It’s Time for New Tires” and
“Wheel Replacement” later in this section for
more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first rotation is the most important.
See “Scheduled
Maintenance Services’’ in the Index for scheduled
rotation intervals.
n
*
I1
When rotating your tires, always use the correct rotation
pattern shown here.
Don’t include the compact spare tire in your tire rotation. \
After the tires have been rotated, adjust the front and
rear inflation pressures
as shown on the Tire-Loading
Information label. Make certain that all wheel nuts are
properly tightened. See “Wheel
Nut Torque” in
the Index.

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
-
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose
after
a time. The wheel could come off and cause
an accident. When you change
a wheel, remove
any rust or dirt from places where the wheel
attaches to the vehicle. In an emergency, you can
use
a cloth or a paper towel to do this; but be
sure to use
a scraper or wire brush later, if you
need to, to get
all the rust or dirt off. (See
“Changing
a Flat Tire” in the Index.) When
It’s Time for New Tires
One way to tell when it’s
time for new tires
is to
check the treadwear indicators, which will
appear when your tires have
only
1/16 inch (1.6 mm) or
less of tread remaining.
You need a new tire if any
of the following statements
are true:
0 You can see the indicators at three or more places
0 You can see cord or fabric showing through the
0 The tread or sidewall is cracked, cut or snagged deep
enough to show cord or fabric.
0 The tire has a bump, bulge or split.
0 The tire has a puncture, cut or other damage that
around the tire.

can’t be repaired well because
of the size or location
of the damage.

Downloaded from www.Manualslib.com manuals search engine Care of Safety Belts
Keep belts clean and dry.
I
Do not bleach or dye safety belts. If’ you do, it
may severely weaken them. In a crash, they
might not be able to provide adequate protection. Clean safety belts
only with mild soap and
lukewarm water.
Cleaning Glass Surfaces
Glass should be cleaned often. GM Glass Cleaner (GM
Part No. 1050427) or a liquid household glass cleaner
will remove normal tobacco smoke and dust films on
interior glass.
Don’t
use abrasive cleaners on glass, because they may
cause scratches. Avoid placing decals on the inside rear
window, since they may have to be scraped
off later.
If abrasive cleaners are used on the inside of the rear
window, an electric defogger element may be damaged.
Any temporary license should not be attached across the
defogger grid.
Cleaning the Outside of the
Windshield and Wiper Blades
If the windshield is not clear after using the windshield
washer, or if the wiper blade chatters when running, wax, sap or other material may be on the blade or ‘windshield.
Clean the outside of the windshield with GM Windshield Cleaner, Bon
Ami@ Powder (non-scratching glass cleaning
powder), GM
Part No. 1050011. The windshield is clean if
beads do not form when you rinse it with water.
Grime from the windshield will stick to the wiper blades
and affect their performance. Clean the blade by wiping
vigorously with a cloth soaked in full-strength windshield
washer solvent. Then rinse the blade with water.
Check the wiper blades and clean them as necessary;
replace blades that look worn.
Weatherstrips
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply silicone
grease with a clean cloth at least every
six months.
During very cold, damp weather more frequent application may be required. (See “Recommended
Fluids and Lubricants” in the Index.)

The 8th character in your VIN is the engine code. This
code will help you identify your engine, specifications
and replacement parts.

NOTICE:
Don’t add anything electrical to your Chevrolet
unless
you check with your dealer first. Some
electrical equipment can damage your vehicle
and the damage wouldn’t
be covered by your
warranty. Some add-on electrical equipment
can keep other components from working as
they should.
Your vehicle has an air bag system. Before attempting to
add anything electrical to your Chevrolet, see “Servicing
Your Air Bag-Equipped Chevrolet” in the Index.

Downloaded from www.Manualslib.com manuals search engine Headlamp Wiring Fuses and Circuit Breakers
The
headlamp wiring is protected by fuses. Should your
headlamps fail to function, have your headlamp system
checked right away.
Windshield Wiper Fuse
The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools.
If the overload is caused by some electrical problem,
have it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power
windows and other power accessories. When the current
load
is too heavy, the circuit breaker opens and closes,
protecting the circuit until the problem is fixed. The
wiring circuits in your vehicle
are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links. This greatly reduces the
chance of damage caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical size
and rating.
If you ever have
a problem on the road and don’t have
a spare fuse, you can “borrow” one that has the same
amperage. Just pick some feature of your vehicle that
you can get along without
-- like the radio or cigarette
lighter
-- and use its fuse if it is the correct amperage.
Replace it as
soon as you can.
There are
two fuse blocks in your vehicle: the instrument
panel fuse block and the engine compartment
fuse block.

Downloaded from www.Manualslib.com manuals search engine How This Section is Organized
The remainder of this section is divided into five parts:
“Part
A: Scheduled Maintenance Services” shows
what to have done and how often. Some of these
services can be complex,
so unless you are technically
qualified and have the necessary equipment, you should
let your dealer’s service department or another qualified
service center do these jobs.
’ A CAUTION:
Performing maintenance work on a vehicle can
be dangerous. In trying to do some jobs, you can
be seriously injured.
Do your own maintenance
work only if you have the required know-how
and the proper tools and equipment for the
job.
If you have any doubt, have a qualified
technician do the work.
If you are skilled enough to do some work on your
vehicle, you will probably want to get the service
information
GM publishes. See “Service and Owner
Publications” in the Index. “Part
B: Owner Checks and
Services’’ tells you what
should
be checked and when. It also explains what you
can easily do to help keep your vehicle in good condition.
“Part C: Periodic Maintenance Inspections” explains
important inspections that your Chevrolet dealer’s
service department or another qualified service center
should perform.
“Part
D: Recommended Fluids and Lubricants” lists
some products
GM recommends to help keep your
vehicle properly maintained. These products,
or their
equivalents, should be used whether you do the work
yourself or have it done.
“Part
E: Maintenance Record” provides a place for
you to record the maintenance performed on your
vehicle. Whenever any maintenance is performed, be
sure to write it down in this
part. This will help you
determine when your next maintenance should be done. In addition, it is a good idea to keep your maintenance
receipts. They may be needed to qualify your vehicle for warranty repairs.

Downloaded from www.Manualslib.com manuals search engine Part A: Scheduled Maintenance
Services
Using Your Maintenance Schedule
We at General Motors want to help you keep your
vehicle in good working condition. But we don’t know
exactly how you’ll drive it.
You may drive very short
distances only
a few times a week. Or you may drive
long distances all the time in very hot, dusty weather.
You may use your vehicle in making deliveries. Or
you may drive it to work, to do errands or in many
other ways.
Because
of all the different ways people use their GM
vehicles, maintenance needs vary.
You may even need
more frequent checks and replacements than you’ll find
in the schedules in this section.
So please read this
section and note how you drive. If you have any
questions on how to keep your vehicle in good
condition, see your Chevrolet dealer. The proper fluids and lubricants to use are listed
in Part D.
Make sure whoever services your vehicle uses these. All
parts should be replaced and all necessary repairs done
before you or anyone else drives the vehicle.
These schedules are for vehicles that:
carry passengers and cargo within recommended
limits.
You will find these limits on your vehicle’s
Tire-Loading Information label. See “Loading Your
Vehicle” in the Index.
are driven on reasonable road surfaces within legal
use the recommended fuel. See “Fuel” in the Index.
driving limits.
Selecting the Right Schedule
First you’ll need to decide which of the two schedules
is
right for your vehicle. Here’s how to decide which
schedule to follow:
This part tells
you the maintenance services you should
have done and when you should schedule them. If
you
go to your dealer for your service needs, you’ll know
that GM-trained and supported service people will
perform the work using genuine
GM parts.

Downloaded from www.Manualslib.com manuals search engine Short Trip/City Maintenance Schedule I
The services shown in this schedule up to 100,000 miles
( 166 000 km) should be performed after 100,000 miles
(166
000 km) at the same intervals. The services shown
at 150,000 miles
(240 000 km) should be performed at
the same interval after 150,000 miles
(240 000 km).
See “Owner Checks and Services” and “Periodic
Maintenance Inspections” following.
Footnotes
The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall
liability prior to the
completion of the vehicle’s useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the maintenance
be recorded.
# Lubricate the suspension and steering linkage.
+ A good time to check your brakes is during tire
rotation. See “Brake System Inspection” under “Periodic
Maintenance Inspection” in
Part C of this schedule.
++ If you drive in a highly corrosive environment,
your brake calipers may require additional inspection
and service, at every other tire rotation. See
“Caliper/Knuckle Maintenance Inspection’’ under
“Periodic Maintenance Inspections’’ in Part
C of
this schedule.
