1983 Chevrolet P30 Service and Repair Manual

This factory service and repair manual for the 1983 Chevrolet P30 addresses a truck that existed in two very different states: a finished two-door van and a bare chassis, sold as Step-Van Delivery and Base Stripped. Four engines carry either one — a 292-cubic-inch inline-six, gasoline V8s of 350 and 454 cubic inches, and a 379-cubic-inch diesel V8. Because what sits ahead of the firewall changes so completely between them, specifications, torque values and diagnostic sequences are given per engine rather than as one shared chapter.

Known issues on the 1983 P30. The manual is the reference for routine and heavy work alike: valve train and timing specifications, fuel delivery and emissions checks, cooling system service, transmission and driveline procedures, brake hydraulics and adjustment, front end alignment figures, and the wiring diagrams for lighting, charging and starting on a chassis whose upper body came from a separate builder.
