Rear Axle
When to Check and Change Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant and when to change it. See
“Scheduled Maintenance Services” in the Index.
How to Check Lubricant
If the level is below the bottom of the filler plug hole,
you’ll need to add some lubricant. Add enough lubricant
to raise the level to the bottom
of the filler plug hole,
What to Use
Standard Differential
Use Axle Lubricant (GM Part No. 12345977) or SAE
80W-90 GL-5 gear lubricant.
Limited-Slip Differential
To add lubricant when the level is low, use Axle
Lubricant (GM
Part No. 12345977). To completely refill
after draining, add 4 ounces
(1 18 ml) of Limited-Slip
Differential Lubricant Additive (GM Part
No. 1052358).
Then fill to the bottom of the filler plug hole with Axle
Lubricant
(GM Part No. 12345977).
Engine Coolant
The cooling s stem in your vehicle is filled with new
DEX-COOL 8 engine coolant. This coolant is designed
to remain in your vehicle for
5 years or 150,000 miles
(240
000 km) whichever occurs first, if you add only
DEX-COOL’ extended life coolant.
The following explains your cooling system and how
to add coolant when it is low. If you have a problem
with engine overheating or if you need to add coolant
to your radiator, see “Engine Overheating” in the Index.
A
50150 mixture’ of water and DEX-COOL@
coolant will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
e Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.
5.7L Engine Only If
this light comes on,
it
means
you’re low on
engine coolant.
Adding Coolant to the Recovery Tank
If you need more coolant, add the proper DEX-COOL@
coolant mixture at the coolant recovery tank, but only
when your engine is cool. If the tank is very low or
empty, also add coolant to the radiator.
See “Engine
Overheating” in the Index
for information.
Turning the raalator pressure cap when the
engine
and radiator are hot can allow steam and
scalding liquids to blow out and burn you badly.
With the coolant recovery tank, you
will almost
never have
to add coolant at the radiator. Never
turn the pressure cap
-- even a little -- when the
engine and radiator are hot,
Add coolant mixture at the recovery tank, but be careful
not to spill it.
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it
will burn if the engine parts are hot
, enough. Don’t spill coolant on a hot engine.

manual under Part C “Periodic Maintenance
Same driving conditions or climates may cause a brake
squeal when the brakes are. first applied or lightly
applied. This does not mean something is wrong with
your brakes.
See “Caliper/Knuckle Maintenance Inspection’’ in
Section
7 of this manual under Part C “Periodic
Maintenance Inspections.”
If you have rear drum brakes, they don’t have wear
indicators, but
if you ever hear a rear brake rubbing
noise, have the rear brake linings inspected. Also, the
rear brake drums should
be removed and inspected each
time the tires are removed for rotation or changing.
When
you have the front brakes replaced, have the rear
brakes inspected, too.
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in pedal
travel.
This could be a sign of brake trouble.
Brake Adjustment
Every time you make a moderate brake stop, your disc
brakes adjust for wear.
If you rarely make a moderate or
heavier stop, then your brakes might not adjust correctly.
If you drive in that way, then -- very carefully -- make
a few moderate brake stops about every 1,000 miles
(1 600 km), so your brakes will adjust properly.
If your brake pedal goes down farther than normal, your
rear drum brakes may need adjustment. Adjust them by
backing up and firmly applying the brakes
a few times.

Mixing tires could cause you to lose control while
driving.
If you mix tires of dif€erent sizes or types
(radi,al
and bias-belted tires), the vehicle may not
handle properly, and
you could have a crash.
Using tires of different sizes may also cause
damage to
your vehicle. Be sure to use the same
size and type tires on all wheels.
It's
all right to drive with your compact spare,
though. It was developed for use 0n your vehicle.
Uniform Tire Quality Grading
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear, traction and temperature performance, (This
applies
only to vehicles sold in the United States.) The
grades are molded
on the sidewalls of most passenger car
tires. The Uniform Tire Quality Grading system
does not apply
to deep tread, winter-type snow tires,
space-saver or temporary
use spare tires, tires with
nominal rim diameters
of 10 to 12 inches (25 to 30 cm),
or to some lirnited-pro'duction tires.
While the tires available
on General Motors passenger
cars and light trucks may vary with respect to these
grades, they must also conform to Federal safety
requirements and additional General Motors Tire
performance Criteria
(TPC) standards.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate
of the tire when tested under controlled
conditions
on a specified government test course. For
example, a tire graded 150 would wear one and a half
(1 1/2) times as well on the gov'esnrnent course as a tire
graded
100. The relative performance of tires depends
upon the actual conditions
of their use, however, and
may depart significantly from the norm due to variations
in driving habits, service practices and differences in
road characteristics
and climate.

Mix Multi-Purpose Powdered Cleaner following the
directions
on the container label.
Use suds only and apply with a clean sponge. Don’t
saturate the material and don’t rub
it roughly.
As soon as you’ve cleaned the section, use a sponge
to remove the suds.
Rinse
the section with a clean, wet sponge.
Wipe off what’s left with a slightly damp paper towel
or cloth.
Dry it immediately with a blow dryer.
Wipe with
a clean cloth.
Using Solvent-Type Cleaner on Fabric
First, see if you have to use solvent-type cleaner at all.
Some spots and stains will clean off better with just
water and mild soap. If
you need to use a solvent:
1. Gently scrape excess soil from the trim material with
a clean, dull knife or scraper.
2. Use very little cleaner, light pressure and clean cloths
(preferably cheesecloth). Cleaning should start at the
outside
of the stain, “feathering” toward the center.
3. Keep changing to a clean section of the cloth.
4. When you clean a stain from fabric, immediately
dry the area with a blow dryer to help prevent a
cleaning ring.
Special Cleaning Problems
Greasy or Oily Stains
Stains caused by grease, oil, butter, margarine, sho’e
polish, coffee with cream, chewing gum, cosmetic
creams, vegetable oils, wax crayon, tar and asphalt can
be removed as follows:
1. Carefully scrape off excess stain.
2. Follow the solvent-type instructions described earlier.
Shoe polish, wax crayon, tar and asphalt will stain
if left
on a vehicle’s seat fabric. They should be removed as
soon as possible. Be careful, because
the cleaner wiIl
dissolve them and may cause them to spread.

Cleaning Your Convertible Top
Your c’onvertible top should be cleaned often. If you use
an automatic car wash, use one with water jets and
hanging cloths. High pressure car washes may cause
water
to enter your vehicle.
When you hand wash the top,
do it in partial shade. Use
a mild
soap, lukewarm water and a soft sponge, A
chamois or cloth may leave lint on the top, and a brush
can chafe the threads in the top fabric. Don’t use
detergents, harsh cleaners, solvents or bleaching agents.
When you clean the top, put one hand under it to
support it. Wet the entire vehicle and wash the top
evenly to avoid spots or rings. Let the soap remain on
the fabric for
a few minutes. When the top is really
dirty, use a mild foam-type cleaner. Thoroughly rinse
the entire vehicle, then let
the top dry in direct sunlight.
Aluminum or Chrome Wheels
(I€ Equipped)
Keep your wheels clean using a soft clean cloth with
mild soap and water. Rinse with clean water. After
rinsing thoroughly,
dry with a soft clean towel. A wax
may then be applied.
The surface
of these wheels is similar to the painted
surface
of your vehicle. Don’t use strong soaps,
chemicals, abrasive polishes, abrasive cleaners
or
abrasive cleaning brushes on them because you could
damage the surface. You may use chrome polish on
chrome wheels, but avoid any painted surface of the
wheel, and buff off immediately after application.
Don’t
take your vehicle through an automatic car wash
that has silicon carbide tire cleaning brushes. These
brushes can also damage the surface
of these wheels.
To protect the convertible top:
After you wash the vehicle, make sure the top is
completely
dry before you lower it.
Don’t get any cleaner on the vehicle’s painted finish;
it
could leave streaks.
~f YOU decide to go through an automatic car wash,
ask the manager if the equipment could damage
your top.

Main Fuse Block
The other is in the engine compartment. Open the cover
on either of the boxes to expose the €uses.
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 correct size.
If
you ever have a problem on the road and don’t have a
spare €use, you can “borrow”
one. Just pick some
feature
of your car that you can get along without -- like
the radio or cigarette lighter -- and use its fuse, if it is
the size you need. Replace it as soon as you
can.
