1989 Chevrolet C3500 Service and Repair Manual
This factory service and repair manual for the 1989 Chevrolet C3500 answers to three trim levels — Cheyenne, Scottsdale and Silverado — and to the chassis beneath them. A buyer picked a standard cab pickup, an extended cab pickup or a bare cab and chassis, then one of three overhead-valve V8s: the 454-cubic-inch 7.4-liter and the 350-cubic-inch 5.7-liter on gasoline, or the 379-cubic-inch 6.2-liter on diesel. The manual keeps those engines apart where they differ and merges the coverage where the truck is common, which is most of the chassis.

Known issues on the 1989 C3500. Two recalls stand on the federal record for this year. One concerns replacement fuel filters that seal poorly at the connection, letting fuel escape where an ignition source could set it alight. The other is a labeling fault: the truck carried wrong instructions for adjusting the rear lap-shoulder belts, so a belt set by the book would not restrain an occupant properly in a crash or a sudden stop. Owners logged nine complaints, split mainly between tires and visibility at three each, with one on the power train. Fuel line service, restraint adjustment and driveline diagnosis all have procedures here.
