This factory service and repair manual for the 1985 Chevrolet P60 belongs to a heavy cab-forward chassis sold as P6T042 and P6T042 Stripped. Its three V8s cover a wide range of duty: a 5.7L gasoline engine, a 6.0L gasoline engine, and an 8.2L diesel of 501 cubic inches. Specifications, torque values, wiring diagrams and diagnostics are set out per system, so an operator running the diesel and one running a gasoline V8 each find their own procedures rather than a compromise between them.
