This factory service and repair manual for the 1984 Chevrolet P30 is written around one chassis and the several ways it was finished. Two body configurations are listed, a two-door van and bare rails, along with two trims, Base Stripped and Step-Van Delivery. The engine is one of four: a 4.8L inline-six of 292 cubic inches, a 5.7L or 7.4L gasoline V8, or the 6.2L diesel V8. Torque values, clearances, wiring diagrams and diagnostic steps follow the systems those combinations create.

Known issues on the 1984 P30. No recalls stand against the 1984 P30 and no owner complaints have been recorded, so the federal record is clean. The manual is therefore read for what it specifies rather than what it warns about: engine mechanical and fuel work across gasoline and diesel, cooling and charging service, transmission and rear axle overhaul, brake and parking brake adjustment, steering linkage inspection, and frame and body hardware. Diagnostics are laid out as test sequences with the measurements a technician needs at each step.
