Service Manuals Service manuals contain diagnostic and repair information for all chassis and body systems. They may be useful for owners whowish to get a greater understanding of their vehicle. They are also useful for owners with the appropriate skill level or training who wish to perform "do-it-yourself" service. These are authentic General Motors service manuals meant for professional, qualified technicians. Service Bulletins Service bulletins covering various subjects are regularly sent to all General Motors dealerships. GM monitors product performance in the field. When service methods are found which promote bettefservice on GM vehicles, bulletins are created to help the technician perform better service. Service bulletins may involve any number of vehicles. Some will describe inexpensive service; otherswill describe expensive service. Some will advise of new or unexpected conditions, and others may help avoid future costly repairs.
