1982 GMC G2500 Service and Repair Manual

Four body configurations are listed, all of them three-door, covering standard and extended cargo vans and standard and extended passenger vans, and three trims sit across them in Rally, Rally STX and Vandura form.

Known issues on the 1982 G2500. The manual covers the everyday work: service specifications for the inline-six and both gasoline V8s, torque values through the driveline, brakes, steering and suspension, and wiring diagrams for the lighting and charging circuits that a cargo or passenger body leans on. Diagnostics accompany each of those systems, which on a van of this age is what actually gets used week to week.
