GMC Truck regularly sends its dealers useful service bulletins about GMC
Truck products. GMC Truck 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 GMC Truck dealer or a qualified technician may have to
determine if a specific bulletin applies to your vehicle.
Individual PSP’s
If you don’t want to buy all the PSP’s issued by GMC Truck 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:
8-7
ProCarManuals.com

What You’// Find in the Index;
A list of all PSP’s published by GMC Truck in a model year. PSP’s
covering all models of GMC light trucks 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 GMC Truck 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
1939-1 994 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 GMC
Truck dealer.
You can ask to see them.
A Very lmportant 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.
GMC Truck reserves
the right to change these procedures without notice
after November, 1992.
