1982 GMC C2500 Suburban Service and Repair Manual

This factory service and repair manual for the 1982 GMC C2500 Suburban addresses a four-door sport utility that could leave the assembly line with any of five engines: the 5.0L, 5.7L and 7.4L overhead-valve gasoline V8s, the 4.8L inline-six, or the 6.2L V8 diesel. Four trims sit on that one body — Base, High Sierra, Sierra Classic and Sierra Grande — so most of what separates two of these wagons is under the hood. The book is organized by system, with procedures, specifications, torque values, wiring diagrams and diagnostics for each of them.

Known issues on the 1982 C2500 Suburban. The manual carries a considerable load for a wagon with five engine choices. Engine work alone runs from the 4.8L inline-six to the 7.4L V8 and the 6.2L diesel, and beyond that the driveline, brakes, steering, suspension, body and electrical systems each get their own procedures, specifications, torque values, wiring diagrams and diagnostics.
