1986 Chevrolet K30 Service and Repair Manual

This factory service and repair manual for the 1986 Chevrolet K30 keeps four engines and four bodies in one volume, which makes it less a book about what is new and more a book about precision. Whether the truck carries the 4.8L inline-six of 292 cubic inches, the 5.7L or 7.4L gasoline V8, or the 6.2L diesel of 379, and whether it is a pickup or a cab and chassis, the procedures give the values for that exact combination — Custom, Scottsdale or Silverado — rather than an average of them.
