1991 Chevrolet V3500 Service and Repair Manual
This factory service and repair manual for the 1991 Chevrolet V3500 lists two trims, Cheyenne and Silverado, one body in the four-door crew cab pickup, and three naturally aspirated V8 engines: the 454-cubic-inch 7.4L and the 350-cubic-inch 5.7L running gasoline, and the 379-cubic-inch 6.2L running diesel. Choosing between them changes the fuel and starting systems entirely, and the manual treats each engine as its own subject, with its own specifications, torque values and diagnostic routines.

Known issues on the 1991 V3500. The federal record is clean for this model year — no recalls have been issued and no owner complaints logged. The manual is then a reference for the repairs a working truck accumulates on its own: cooling and lubrication service, injection and glow system work on the diesel, fuel and ignition diagnosis on the gasoline engines, driveline and axle overhaul, brake and suspension specifications with torque values, and the wiring diagrams for tracing faults circuit by circuit.
