1985 Chevrolet C20 Service and Repair Manual
This factory service and repair manual for the 1985 Chevrolet C20 lists six engines for three body configurations, which is a great many combinations to keep straight. A 4.3L V6 of 262 cubic inches and a 4.8L inline-six of 292 sit below the 5.0L, 5.7L and 7.4L gasoline V8s, and a 6.2L diesel V8 of 379 cubic inches stands apart from all of them. The bodies are a two-door standard cab pickup, a four-door crew cab pickup and a two-door cab and chassis, in Custom, Scottsdale or Silverado trim.

Known issues on the 1985 C20. The federal record holds one recall, and it applies to a replacement oil filter rather than to anything installed at the factory: the seal can be inadequate, engine oil can escape and a fire can follow. Two owner complaints, both about tires, are the only others on record. Rather than a fault history, this manual gives the working numbers — oil pressure and lubrication specifications, wheel and tire fitting torque, and the full set of engine, driveline, brake, steering and electrical procedures for every configuration listed.
