1983 GMC C6000 Service and Repair Manual
This factory service and repair manual for the 1983 GMC C6000 is a five-engine book covering one trim code, C6D042, in two forms: a 2-door conventional cab and chassis and a medium conventional tractor truck.

Known issues on the 1983 C6000. No recalls and no owner complaints stand against the 1983 C6000 in NHTSA's records. For a truck that could leave the factory with any of five engines, the practical benefit of a manual like this is in sorting out which figures apply: the three gasoline engines and the two naturally aspirated diesels each have their own specifications, service procedures and torque values, and the wiring diagrams and diagnostic charts cover both the tractor and the cab-and-chassis versions.
