1990 Chevrolet R3500 Service and Repair Manual
This factory service and repair manual for the 1990 Chevrolet R3500 comes down to two four-door bodies, a cab and chassis and a crew cab pickup, and three engines to move them: gasoline V8s of 7.4L and 5.7L, 454 and 350 cubic inches, and the 6.2L 379-cubic-inch diesel, all overhead-valve and naturally aspirated. The trims are Cheyenne, Scottsdale and Silverado. Because both bodies are four-door versions of the same truck, most of the procedures apply to either, and the differences are concentrated behind the cab.

Known issues on the 1990 R3500. The federal record is empty for this year — no recalls issued, no owner complaints logged. That says little about how hard these trucks were worked, and wear is what the manual is built around: engine mechanical and cooling specifications for all three V8s, clutch, transmission, driveshaft and axle procedures, brake and steering service, and suspension data. Wiring diagrams and diagnostic charts round it out, each keyed to the system it belongs to.
