1982 GMC C1500 Service and Repair Manual

This factory service and repair manual for the 1982 GMC C1500 covers a pickup sold in two standard cab body variants and five trims, from Base through High Sierra, Sierra Classic, Sierra Grande and Street. Four engines share the chassis: the 5.0L and 5.7L overhead-valve V8s, the 4.1L inline-six and the 6.2L diesel V8, all of them naturally aspirated. Because the diesel and the gasoline engines call for very different service data, the procedures, specifications, torque values, wiring diagrams and diagnostics are separated by system and by engine.
