1993 BUICK LESABRE service

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.

..

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.
