1993 BUICK SKYLARK belt

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 had
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 a
“MS”
(for mud and snow).
If you ever replace your tires with those not having a
TPC Spec number, make sure they are the same size,
load range, speed rating and construction type (bias,
bias-belted or radial) as your original tires.
A CAUTION:
Mixing tires could cause you to lose control
while driving.
If you mix tires of different sizes or
types (radial and bias-belted tires), the vehicle
may not handle properly, and you could have a
crash. 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 limited use on your
vehicle.
I
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.)
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
245

Care of Safety Belts
Keep belts clean and dry.
/! CAUTION:
1
Do not bleach or dye safety bc s. If you do, it 1
may severely weaken them. In a crash they might
not be able to provide adequate protection. Clean
safety belts only
-th mild soap and lukewarm I
'ater.
I
Glass
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.
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
or other material may be on the blade or windshield.
Clean the outside of the windshield with GM
Windshield Cleaner, Bon-Ami Powders
(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.
Cleaning the Outside of Your Buick
The paint finish on your vehicle provides beauty, depth
of color, gloss retention and durability.

“SG, designation may be shown alone or in
combination with others, such as “SG/CC”,
“SG/CD” or “SF,
SG, CC,” etc. To determine the
preferred viscosity for your vehicle’s engine (e.g.,
SAE 5W-30 or SAE 10W-30), see “Engine Oil” in

for uneven wear or damage. If you see irregular or
premature wear, check
the wheel alignment. Check
for damaged wheels also.

Inspect the belt(s) for cracks, fraying, wear and
proper tension. Replace as needed.
6. Cooling System Service* -- Drain, flush and refill
the system with new or approved recycled coolant
conforming to GM Specification 1825M. Keep
coolant at the proper mixture as specified. See
“Coolant” in the Index. This provides proper freeze
