1983 Chevrolet K20 Suburban Service and Repair Manual

This factory service and repair manual for the 1983 Chevrolet K20 Suburban comes down to a choice between two naturally aspirated V8s, a 6.2L diesel of 379 cubic inches and a 5.7L gasoline unit of 350, in one four-door sport utility body sold as a Custom or a Silverado. The narrow list works in a technician's favor, since the specifications, torque values and diagnostic charts point at one of two engines and the rest of the book applies to every vehicle in the range.

Known issues on the 1983 K20 Suburban. The federal record for the 1983 K20 Suburban is clean, carrying neither a recall nor a complaint from an owner. Coverage is what the book is for, then. The diesel and gasoline V8s are each documented with procedures, specifications and torque values; the four-door body is drawn in wiring diagrams; and the brakes, steering, suspension and driveline are given diagnostic sequences rather than general guidance. On a vehicle this old, having the original figures is often the only way to judge what is worn and what is still within limits.
