Known issues on the 1987 C6000. For the 1987 C6000 the federal record is clean in both columns — no recalls and no owner complaints. That leaves the mechanical content as the reason to own the book. It covers the two gasoline V8s and the 8.2L diesel with their own specifications and procedures, gives torque values for engine and chassis fasteners on the tractor and cab-and-chassis builds, and supplies the wiring diagrams and diagnostic sequences needed to trace a fault rather than guess at it.
