Known issues on the 1983 G3500. Nothing appears against the 1983 G3500 on the federal record, neither recalls nor owner complaints at NHTSA. The manual is left to cover the vehicle itself, which here means service procedures and specifications for the gasoline inline-six and V8 and separate ones for the 6.2L diesel, torque values through the driveline and brakes, wiring diagrams for the van and cutaway bodies, and diagnostics for each of those systems. On a chassis often built out by an upfitter, that ordinary data is what keeps a repair from turning into guesswork.
