Known issues on the 1995 C6000 Topkick. NHTSA lists no recalls and no owner complaints for the 1995 C6000 Topkick, so the federal record on this model year is clean. The manual therefore reads as a working reference. It gives the diagnostic procedures and specifications for the turbocharged 6.6L diesel and for both gasoline V8s, the torque values that go with engine and chassis fasteners, and the wiring diagrams for the conventional cab and chassis — the material a shop needs once a truck is old enough that guesswork gets expensive.
