1988 Chevrolet C3500 Service and Repair Manual

This factory service and repair manual for the 1988 Chevrolet C3500 covers a one-ton truck sold three ways — standard cab pickup, extended cab pickup and cab and chassis — with three overhead-valve V8s behind the grille: the 7.4-liter of 454 cubic inches, the 5.7-liter 350 and the 6.2-liter 379-cubic-inch diesel. Cheyenne, Scottsdale and Silverado sit above that hardware as trim levels. Because two of the three engines burn gasoline and the third burns diesel, the starting and fuel material splits by engine family, and the specifications and torque values follow each one separately.
