L1 H 8P7.
GMC Truck regularly sends its dealers useful service bulletins \
about GMC
Truck products. GMC Truck monitors product performance in the f\
ield. 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 us\
e and care
of
your vehicle. Some describe costly repairs. Others describe inex\
pensive 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 trucks. Your
GMC Truck dealer or a qualified technician may have
to determine if a
specific bulletin applies to your vehicle.
You can subscribe to all GMC Truck bulletins. This way you’ll g\
et 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 GMC Truck Product Service Publications (P\
SP’s).
This
will include bulletins for all light trucks (less than 10,000 Ibs. [4536 kg]

particular model. When you buy a subscription, you

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:
What You’ll Find in the Index:
A list of all PSP’s published by GMC Truck in a model year (1989 or
later). PSP’s covering all models of GMC Truck light trucks (less than
10,000 pounds [4536 kg] GVWR) 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 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 f\
or 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 1989-1 993
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
