This factory service and repair manual for the 1982 GMC P3500 covers four engines across two body configurations. The largest is the 7.4L V8 gasoline; below it sit the 5.7L V8 and the 4.8L inline-six, also gasoline, and the 6.2L V8 diesel. Every one is overhead-valve and naturally aspirated. The truck was built as a two-door delivery van and as a chassis, in Base Stripped and Value form. The manual sorts its procedures, specifications, torque values, wiring diagrams and diagnostics by system, so the engine under the cover decides which numbers apply.
