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.
190
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 1990-1993
model years.
Toll-Free Telephone Number
If you want an additional ordering form
for 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.
Chevrolet reserves the right to change
these procedures without notice.
