1991 Chevrolet P30 Service and Repair Manual
This factory service and repair manual for the 1991 Chevrolet P30 has to account for four body configurations, running from a plain chassis to a stripped motorhome chassis, a two-door cab and chassis and a two-door van, sold as Base, Base Delivery and Base Stripped. Five engines back them: a turbocharged 3.9L inline-four diesel, the 6.2L diesel V8, and gasoline units of 4.3, 5.7 and 7.4 liters. Wiring diagrams, torque values, specifications and diagnostics are organized so each combination can be traced on its own.

Known issues on the 1991 P30. Two recalls are recorded against this model year, both of them replacement filtration that does not seal properly. In one, oil escapes the engine and can reach something hot enough to ignite it; in the other, the leak is fuel at the filter connection, with the same consequence. A single owner complaint, on the fuel system, is logged. Fuel line routing, filter service, lubrication specifications and the pressure tests that confirm a good seal are all covered in this manual.
