1986 Chevrolet K10 Service and Repair Manual

This factory service and repair manual for the 1986 Chevrolet K10 has a four-engine spread to work through — a 4.3L V6 of 262 cubic inches, a 5.0L V8 of 305, a 5.7L V8 of 350 and a 6.2L diesel V8 of 379, all naturally aspirated with overhead valves — in a two-door standard cab pickup offered as Custom, Scottsdale and Silverado. The diesel keeps its own injection and diagnostic sections; the gasoline engines share the ignition and emissions material with separate specifications for each displacement.

Known issues on the 1986 K10. Six owner complaints stand against this model year, three of them on the tires, with single reports naming the body structure and steering.
