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 GM Product Service
Publications (PSP’s). This will include bulletins for all
cars sold by GM 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
entitles you to all
PSP’s published by GM during the
model year. You can purchase a subscription and get
pricing information by calling
HELM at 1-800-782-4356.

Individual PSP’s
If you don’t want to buy all the PSP’s issued by GM 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:
A list of all PSP’s published by GM in a model year
(1990 or later).
PSP’s covering all models of GM
cars are listed in the same index.
0 Ordering information so you can buy the specific
PSP’s
you may want.
Price information for the PSP’s you may want to buy.
How You Can Get an Index:
Indexes are published periodically. Most of the PSP’s
which could potentially apply to the most recent GM
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 1990- 1994 model years.
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.
