Downloaded from www.Manualslib.com manuals search engine How You Can Get an Index:
Indexes are published periodically. Most
of the
PSP’s which could potentially
apply to the most recent Chevrolet 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, fjll 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.
Toll-Free Telephone Number
If you want an additional ordering form
€or an index, 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.
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.
