1989 Chevrolet R2500 Service and Repair Manual

This factory service and repair manual for the 1989 Chevrolet R2500 covers one body only, the four-door crew cab pickup, and three engines for it: a 7.4L gasoline V8 of 454 cubic inches, a 5.7L gasoline V8 of 350, and a 6.2L diesel V8 of 379, each overhead-valve and naturally aspirated. Cheyenne, Scottsdale and Silverado are the trims. With a crew cab as the only body, the wiring diagrams and interior procedures have one layout to describe, while the engine chapters split three ways.
