Section C: Periodic Maintenance
Inspections

Inspection
WHAT SHOULD BE DONE
Inspect the front and rear suspension
and steering system for damaged,
loose or missing parts, signs of wear,
or lack of lubrication. Inspect the
power steering lines and hoses for
proper hookup, binding,
leaks,
cracks, chafing, etc. Clean and then inspect the drive axle boot seals for
damage, tears
or leakage. Replace
seals if necessary.
Inspect the complete exhaust system. Inspect the body near the
exhaust system. Look for broken,
damaged, missing or out-of-position
parts as well as open seams, holes,
loose connections, or other
conditions which could cause a heat
build-up in the floor pan or could let
exhaust fumes into the vehicle. See
“Engine Exhaust” in the Index.

interference or binding, and for
damaged
or missing parts. Replace

brake lines and hoses for proper hookup, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads
for wear and rotors for surface
condition. Inspect other brake parts, including calipers, parking brake,
etc. Check parking brake
adjustment.
You may need to have
your brakes inspected more often
if
your driving habits or conditions
result in frequent braking.
NOTE:
A low brake fluid level can
indicate worn disc brake pads which
may need to be serviced. Also,
if the
brake system warning light stays on
or comes on, something may be
wrong with the brake system. See
“Brake System Warning Light” in
the Index. If your anti-lock brake
system warning light stays
on or
comes on, something may be wrong
with the anti-lock brake system. See
“Anti-Lock Brake System Warning

Here you will find out how to contact Buick if you need assistance. This part also tells you how to obtain service

Customer Assistance for Hearing/Speech Impaired ........................................ 298
Reporting Safety Defects ............................................................ 299
ServicePublications ................................................................ 300
Customer Satisfaction Procedure
Your satisfaction and goodwill are important to your
dealer and Buick. Normally,
any problems with the sales
transaction or the operation
of your vehicle will be
resolved by your dealer’s Sales or Service Departments. Sometimes, however, despite the best intentions of all
concerned, misunderstandings can occur. If your
concern has not been resolved to your satisfaction, the
following steps should be taken:
STEP ONE -- Discuss your problem with a member of
dealership management. Complaints can often be
quickly resolved at that level.
If the matter has already
been reviewed with the Sales, Service, or Parts Manager,
contact the owner of
the dealership or the General
Manager.

Service Publications
Information on how to obtain Product Service
Publications, Subscriptions and Indexes
as described
below is applicable only
in the fifty U.S. states (and the
District of Columbia) and only for cars and light trucks
with GVWR less than
10,000 pounds (4 536 kg).
In Canada, information pertaining to Product Service
Bulletins and Indexes can be obtained by writing to:
General Motors of Canada Limited
Service Publications Department
1908 Colonel Sam Dr.
Oshawa, Ontario
L1H 8P7
Buick regularly sends its dealers useful service bulletins
about Buick products. Buick monitors product
performance in the field. We then prepare bulletins for
servicing our products better. Now, you can get these
bulletins too. Bulletins cover various subjects. Some pertain to the
proper use and care of your vehicle. Some describe
costly repairs. Others describe inexpensive repairs which, if done on time with the latest parts, may avoid
future costly repairs. Some bulletins tell a technician
how to repair
a new or unexpected condition. Others
describe a quicker way to fix your vehicle. They can
help a technician service your vehicle better.
Most bulletins apply to conditions affecting a small
number
of cars or trucks. Your Buick dealer or a
qualified technician may have to determine
if a specific
bulletin applies to your vehicle.
You can subscribe to all Buick bulletins. This way you’ll
get them as they come out.
You can wait a while and get
an index to the bulletins.
You can also get individual
bulletins. However, you’ll need
the index to identify
them.

Subscriptions
You can subscribe to all Buick Product Service
Publications (PSP’s). This will include bulletins for all cars sold by Buick and will not be limited to PSP’s
applicable to any particular model. When you buy a
subscription, you will receive the PSP’s in periodic
mailings, shortly after they come out.
A subscription
costs
U.S. $86.50 ($106.50 including a special binder)
and it entitles you to all PSP’s published by Buick
during the model year. You can purchase a subscription
by sending a check or money order to Service
Publications, Post Office Box
1901, Flint, Michigan,
48501, along with the order form located in the
following text. You may get additional subscription
ordering forms by calling the toll-free number shown in
the following text.
Individual PSP’s
If you don’t want to buy all the PSP’s issued by Buick
for all models
in the model year, you can buy individual
PSP’s, such as those which may pertain to a particular
model.
To do this, you will first need to see our index of
PSP’s.
It provides a variety of information. Here’s what
you’ll find
in the index and how you can get one:
What You’ll Find in the Index:
0 A list of all PSP’s published by Buick in a model
year (1989 or later).
PSP’s covering all models of
Buick cars are listed
in the same index.
Ordering information so you can buy the specific
PSP’s you may want.
Price information for the PSP’s you may want to
buy.
301
..

How You Can Get an Index:
Indexes are published periodically. Most of the PSP’s
which could potentially apply to the most recent Buick
models will be listed in the most recent publication for
that model year. This means you may want to wait
until
the end of the model year before ordering an index, if
you are interested in buying PSP’s pertaining to a
current model year car or truck.
Some PSP’s pertaining to a particular model year
vehicle may be published in later years, and these would
be listed in the later year’s index. When you order
an
index for a model year that is not over yet, we’ll send
you the most recently published issue. Check the
ordering form for indexes for earlier model years.
Cut out the ordering form,
fill it out, and mail it in. We
will then see to it that an index is mailed to you. There is
no charge for indexes for the
1989- 1993 model years.
Toll-Free Telephone Number
If you want an additional ordering form for an index or a
subscription, just call toll-free and we’ll be happy to
send you one. Automated recording equipment will take
your name and mailing address. The number to call is
1-800-551-4123.
Copies at Participating Dealers
Copies of Indexes and individual PSP’s are at your
participating Buick dealer. You can ask to see them.
A VERY IMPORTANT REMINDER: These PSP’s are
meant
for technicians. They are not meant for the
“do-it-yourselfer.” Technicians have the equipment,
tools, safety instructions, and know-how to do a
job
quickly and safely.
