This factory service and repair manual for the 1988 Chevrolet P30 spans 292 to 454 cubic inches of engine and two ways of building a truck on top. The inline-six, the 5.7L and 7.4L gasoline V8s and the 6.2L diesel V8 all share the chassis, which reached customers as a two-door van or as bare rails, in Base Stripped and Step-Van Delivery form. Rather than treating that spread as one machine, the manual splits its specifications, torque values, wiring diagrams and diagnostics by system and by engine.

Known issues on the 1988 P30. There are no recalls and no owner complaints on the federal record for the 1988 P30 — the year is clean. That puts the weight on the reference material: compression and valve specifications, fuel and ignition service across gasoline and diesel, cooling, charging and starting diagnostics, clutch, transmission and rear axle procedures, brake hydraulics, steering and front suspension adjustment, and the wiring diagrams a technician needs when tracing a circuit that runs into body work fitted by an outside builder.
