1985 GMC K2500 Service and Repair Manual

This factory service and repair manual for the 1985 GMC K2500 has four engines to account for: the 6.2L diesel V8, the 4.8L inline-six, the 4.3L V6 and the 5.7L V8, all overhead-valve and all naturally aspirated. Two bodies are listed, a standard cab pickup and a cab & chassis, while the trim ladder runs Base, High Sierra and Sierra Classic. Coverage is arranged by system and by engine, so the specification for the V6 is never confused with the one for the diesel.
