This factory service and repair manual for the 1991 Chevrolet C60 Kodiak describes a single-code truck, C6H042, built as a two-door conventional cab and chassis. Three engines were available and the choice is a real one: 366 or 427 cubic inches of naturally aspirated overhead-valve gasoline V8, or a turbocharged 6.6L overhead-valve inline-six diesel. Whichever is fitted, the frame, axles, brakes and cab wiring are shared, and the manual gives its torque values and diagnostics against that common chassis.

Known issues on the 1991 C60 Kodiak. Federally, this year records nothing at all: no recalls filed against the 1991 C60 Kodiak and no owner complaints logged. The manual carries the load instead. It sets out engine specifications, clearances and torque values for the 366- and 427-cubic-inch gasoline V8s and for the turbocharged 6.6L inline-six diesel, then moves through transmission and driveline service, axle work, brake overhaul, steering, and the wiring diagrams and diagnostics for the cab.
