1985 GMC K2500 Suburban Service and Repair Manual

This factory service and repair manual for the 1985 GMC K2500 Suburban is a two-engine book: the 6.2L diesel V8 and the 5.7L gasoline V8, each an overhead-valve unit fed without a turbocharger. One body style, the four-door sport utility, and three trims, Base, High Sierra and Sierra Classic, complete the picture. What that combination gives a shop is depth rather than breadth, with full procedures, specifications and torque values for two engines instead of a thin pass over many.
