1982 Chevrolet K20 Suburban Service and Repair Manual

This factory service and repair manual for the 1982 Chevrolet K20 Suburban covers a single four-door sport utility body offered as a Custom, a Scottsdale or a Silverado, with three engines behind it: a 4.8L overhead-valve inline-six of 292 cubic inches, a 5.7L gasoline V8 of 350 and a naturally aspirated 6.2L diesel V8 of 379.

Known issues on the 1982 K20 Suburban. Two recalls are on the federal record for this year. One is mechanical and serious: rear axle shafts given the wrong heat treatment can break, and when a shaft lets go the wheel and tire assembly can separate from the vehicle. The other covers a replacement oil filter that can seal poorly, allowing the engine to lose oil and creating a fire risk. A single owner complaint concerns the engine and its cooling. Axle, lubrication and cooling procedures, with their torque values and diagnostic steps, are all documented here.
