1982 Chevrolet C20 Suburban Service and Repair Manual
This factory service and repair manual for the 1982 Chevrolet C20 Suburban has to answer for five engines under one hood line: a 4.8L overhead-valve inline-six, three gasoline V8s of 5.0, 5.7 and 7.4 liters, and the 6.2L diesel V8. All of them sit in the same four-door sport utility body, sold as Custom, Scottsdale and Silverado, so the specifications and torque values divide by engine while the chassis, brake and body sections apply to all three trims alike.

Known issues on the 1982 C20 Suburban. Two recalls stand on the federal record. One reaches the truck through replacement parts: an oil filter that can seal poorly, bleed engine oil out under pressure and set up a fire. The other is structural in the driveline, where rear axle shafts given improper heat treatment can fracture and let a wheel and tire leave the vehicle. A single owner complaint was logged for the year, on the seat belts. Axle shaft service, lubrication procedures and restraint inspection are all specified here.
