1991 Chevrolet W5500 Tiltmaster Service and Repair Manual
This factory service and repair manual for the 1991 Chevrolet W5500 Tiltmaster documents a four-door sport utility offered in Base, LT and SS trim, with a choice of three naturally aspirated gasoline engines: the 364-cubic-inch 6.0L V8 and the 325-cubic-inch 5.3L V8, both overhead-valve, and the 256-cubic-inch 4.2L inline-six with double overhead camshafts. The book is used by first fixing the engine, since ignition, fuel and mechanical figures differ across all three, and then working through the shared chassis and body sections.

Known issues on the 1991 W5500 Tiltmaster. Because the federal record carries neither a recall nor an owner complaint for this year, the manual is a reference rather than a corrective. It sets out ignition and fuel system service for each of the three gasoline engines, engine mechanical clearances and torque values, cooling and lubrication capacities, transmission, driveshaft and axle procedures, brake, steering and suspension specifications, and wiring diagrams supported by the diagnostic charts that go with the body and chassis circuits.
