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 federal record for this model year is clean: no recalls and no owner complaints are logged with NHTSA. That leaves the manual to carry the whole load on its own, which for a wagon with five engine choices is considerable. 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.
