1989 Chevrolet C1500 Service and Repair Manual

This factory service and repair manual for the 1989 Chevrolet C1500 has four trims, two cab styles and five engines to keep straight. Base, Cheyenne, Scottsdale and Silverado sit on standard and extended cab pickups, and the range runs from the 4.1L inline-six of 250 cubic inches through the 4.3L V6 of 262 and the 5.0L and 5.7L V8s to the 6.2L diesel V8 of 379 cubic inches, none of them turbocharged. Identifying the truck first and reading the matching specifications second is how the book is meant to be used.

Known issues on the 1989 C1500. Three recalls are recorded. One is a restraint problem of an unusual kind: the instructions supplied for adjusting the rear lap-and-shoulder belts were wrong, so a belt set the way the owner was told would not hold an occupant properly in a crash or hard stop. The other two concern replacement filters, a fuel filter that can leak at a poorly sealed connection and an oil filter that can lose engine oil, each with fire named as the risk. Of the thirty-three complaints, eight are on service brakes, five on the power train and four on exterior lighting.
