1984 Chevrolet C20 Suburban Service and Repair Manual
This factory service and repair manual for the 1984 Chevrolet C20 Suburban is written for three trims, Custom, Scottsdale and Silverado, sharing one four-door sport utility body and drawing on four overhead-valve engines: the 5.0L, 5.7L and 7.4L gasoline V8s and the 6.2L diesel V8. Because a diesel sits alongside three gasoline engines, the fuel and emissions material is kept apart engine by engine, while the driveline, brake and chassis procedures run common to the whole range.

Known issues on the 1984 C20 Suburban. The federal record holds one recall for this year, and its mechanism is a seal that does not hold: a replacement oil filter that can leak engine oil under pressure, with fire the consequence if that oil reaches something hot. Four owner complaints follow, spread thinly across the electrical system, the tires and the service brakes rather than concentrated anywhere. Brake hydraulics, wiring diagnosis and engine lubrication each carry their own procedures, specifications and torque values here.
