This factory service and repair manual for the 1983 GMC P3500 is arranged for a truck that could arrive with any of four engines: a 7.4L V8, a 5.7L V8 or a 4.8L inline-six on gasoline, or a 6.2L V8 on diesel, none of them force-fed and all with overhead valves. Bodies were the two-door delivery van and the chassis; trims, Base Stripped and Value. Look-up runs by system, procedures first, then specifications, torque values, wiring diagrams and the diagnostic checks that go with each.

Known issues on the 1983 P3500. NHTSA has recorded no recalls and no owner complaints against the 1983 P3500, so the federal record is clean. The reference value here is in breadth rather than in defect history: four engines, two body types and one set of procedures, specifications and torque values that covers them, plus wiring diagrams and diagnostics for the electrical systems that a van body and a bare chassis handle differently.
