I NOTICE:
If you use an improper coolant mix, your engine
could overheat and be badly damaged. The
repair cost wouldn’t be covered by your
warranty.
Too much water in the mix can fie&
and crack the engine, radiator, heater core and
other parts.
To Check Coolant
When your engine is cold, the coolant level should be at
the
COLD mark or a little higher. When your engine is
warm, the level should be up to the HOT mark or a little
higher.

NOTICE:
Your radiator cap is a 15 psi (105 kPa)
pressure-type cap and must be tightly installed
to prevent coolant loss and possible engine
damage from overheating. Be sure the arrows on
the cap line up with the overflow tube on the
radiator filler neck.
When you replace your radiator pressure cap, an AC@
cap is recommended.
Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine coolant system.
The thermostat stops the
flow of coolant through the radiator until the coolant
reaches a preset temperature.
When you replace your thermostat, an
AC@ thermostat
is recommended.

How To Check Power Steering Fluid
When the engine compartment is cool, unscrew the cap
and wipe the dipstick with a clean rag. Replace the cap
and completely tighten
it. Then remove the cap again
and look at the fluid level on the dipstick.

Downloaded from www.Manualslib.com manuals search engine Inflation - Tire Pressure
The Tire-Loading Information label which is on the
inside of the
trunk lid shows the correct inflation
pressures for your tires, when they’re cold. “Cold”
means your vehicle has been sitting for at least three
hours
or driven no more than a mile.
NOTICE:
Don’t let anyone tell you that underinflation or
overinflation
is all right. It’s not. If your tires don’t
have enough
air (underinflation) you can get:
Too much flexing
Too much heat
0 Tire overloading
Bad wear
Bad handling
Bad fuel economy.
If your tires have too much
air (over
you can get:
Unusual wear
Bad handling
Rough ride inflation),
0 Needless
damage from road hazards. 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 kPa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. Simply looking at the tires will not tell you the
pressure, especially
if you have radial tires -- which
may look properly inflated even
if they’re underinflated.
If your tires have valve caps, be sure to put them back
on. They help prevent leaks by keeping out dirt and
moisture.
Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles
(10
000 to 13 000 km) for any signs of unusual wear. If
unusual wear is present, 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.

Downloaded from www.Manualslib.com manuals search engine 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:
You can see the indicators at three or more places
around the tire.
You can see cord or fabric showing through the tire’s
rubber.
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
can’t be repaired
well because of the size or location
of the damage.
Buying New Tires
To find out what kind and size of tires you need, look at
the Tire-Loading Information label.
The tires installed on your vehicle when
it was new a
Tire Performance Criteria Specification (TPC Spec)
number on each tire’s sidewall. When you get new tires,
get ones with that same TPC Spec number. That way,
your vehicle will continue to have tires that are designed
to give proper endurance, handling, speed rating,
traction, ride and other things during normal service
on your vehicle. If your tires have an all-season tread
design,
the TPC number will be followed by an “MS”
(for mud and snow).

Windshield and Wiper Blades
If the windshield is not clear after using the windshield
washer, or if the wiper blade chatters when running, wax
or other material may
be on the blade or windshield.
Clean the outside
of the windshield with GM
Windshield Cleaner, Bon-Ami Powder@ (GM Part
No. 1050011). The windshield is clean if beads do
not form when you rinse
it with water.
Clean the blade by wiping vigorously with
a cloth
soaked in full strength windshield washer solvent. Then
rinse the blade with water.
Wiper blades should be checked
on a regular basis and
replaced when 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.)
Cleaning the Outside of Your
Chevrolet
The paint finish on your vehicle provides beauty, depth
of color, gloss retention and durability.
Washing Your Vehicle
The best way to preserve your vehicle’s finish is to keep
it clean by washing it often with lukewarm or cold
water.
Don’t wash your vehicle in the direct rays of the
sun.
Don’t use strong soaps or chemical detergents. Use
liquid hand, dish or car washing (mild detergent) soaps.
Don’t use cleaning agents that are petroleum based, or
that contain acid or abrasives. All cleaning agents
should be flushed promptly and
not allowed to dry on
the surface, or they could stain. Dry the finish with a
soft, clean chamois or a
100% cotton towel to avoid
surface scratches and water spotting.
High pressure car washes may cause water to enter your
vehicle.

Vehicle Identification Number (VIN)
ENGINE / 19’95 - ASSEMBLY
CODE MODEL YEAR PLANT
This is the legal identifier for your Chevrolet. It appears
on
a plate in the front corner of the instrument panel, on
the driver’s side. You can see
it if you look through the
windshield from outside your vehicle. The VIN also
appears on the Vehicle Certification and Service Parts
labels and the certificates of title and registration.
Engine Identification
The eighth character in your VIN is the engine code.
This code will help you identify your engine,
specifications, and replacement parts.
Service Parts Identification Label
You’ll find this label on your spare tire cover. It’s very
helpful if you ever need to order parts. On this label is:
your VIN,
the model designation,
paint information, and
a list of all production options and special equipment.
Be sure that this label is
not removed from the vehicle.
Add-on Electrical Equipment
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
The headlamp wiring is protected by a circuit breaker in
the underhood electrical center. An electrical overload
will cause the lamps to go on and off, or in some cases
to remain off.
If this happens, have your headlamp
system checked right away.
Windshield Wipers
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.

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.
“Part B: Owner Checks and Services” tells you what
should be checked whenever you stop for fuel. 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.
If you are skilled enough
to do some work on your
vehicle, you will probably want to get the service
information
GM publishes. You will find a list of
publications and how to get them in this manual. See
“Service Publications” in the Index.

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.
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.
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
driving limits.
use the recommended unleaded fuel. See “Fuel” in
the Index.
