This factory service and repair manual for the 1990 Chevrolet C60 lists four engines against a single two-door conventional cab and chassis. Three are gasoline: the 5.7L V8, the overhead-valve 6.0L of 366 cubic inches and a 7.0L of 427 cubic inches. The fourth is the naturally aspirated 8.2L diesel V8. Everything downstream of the flywheel, meaning driveline, brakes, steering, frame and body electrical, is common to the C6D042 chassis, so the manual splits by engine only where it must.

Known issues on the 1990 C60. No recalls and no owner complaints appear on the federal record for the 1990 C60. The manual is written for the work that does come up on a truck like this: identifying which of the four engines is fitted and applying the right specifications and torque values to it, then following the chassis sections through the transmission, driveshafts, axles, brakes and steering, with wiring diagrams and diagnostic charts for the cab and body electrical circuits.
