1986 Chevrolet C50 Service and Repair Manual

This factory service and repair manual for the 1986 Chevrolet C50 carries all three engines offered that year: the 7.0-liter overhead-valve V8 of 427 cubic inches, the 5.7-liter V8 of 350 and the 4.8-liter overhead-valve inline-six of 292, every one naturally aspirated and burning gasoline. The truck they sit in does not vary — a two-door conventional cab and chassis under order code C5D042. Engine mechanical, fuel and cooling material is therefore the widest part of the manual; the frame, axle and brake sections serve every version.

Known issues on the 1986 C50. The engines are the manual's main story, and each is given its own mechanical specifications, fuel and ignition procedures and cooling requirements, with shared coverage of the charging and starting systems, clutch and transmission, driveline and rear axle, brake repair and adjustment, steering and front axle alignment, and cab, frame and electrical work. Torque values and wiring diagrams sit with the procedures they belong to.
