1986 Chevrolet K20 Service and Repair Manual
This factory service and repair manual for the 1986 Chevrolet K20 concerns itself with three engines and two body forms. The engines are a naturally aspirated 6.2L diesel V8, a 4.8L overhead-valve inline-six and a 5.7L gasoline V8; the bodies are a two-door standard cab pickup and a two-door cab and chassis. Custom, Scottsdale and Silverado complete the picture. Coverage is arranged by system, so a diesel truck and a gasoline truck are followed down separate paths from the first specification.

Known issues on the 1986 K20. The 1986 K20 shows a clean federal record, without a recall or a single complaint from an owner. What the manual supplies is the working detail. Specifications and torque values are given for the inline-six, the gasoline V8 and the diesel V8; wiring diagrams cover the cab electrical system; and diagnostic charts run through the brakes, steering, suspension and driveline. That is the material that turns an intermittent fault into a measured one rather than a sequence of replaced parts.
