This factory service and repair manual for the 1990 Chevrolet W5500 Tiltmaster concerns one truck and one engine. The truck is a straight truck on a low tilt cab, built to the W5R042 specification; the engine is a naturally aspirated 6.5L inline-six of 396 cubic inches on diesel. With no alternative engine to allow for, the fuel, cooling and lubrication chapters give a single set of numbers, and the diagnostic charts lead to one injection system rather than branching by powerplant partway through.
