This factory service and repair manual for the 1984 GMC B6000, a cab forward school bus in B6P042 form, has five engines to keep straight: the 6.0L OHV, 7.0L and 5.7L gasoline V8s, the turbocharged 8.2L V8 diesel and its naturally aspirated counterpart. The gasoline and diesel engines share a chassis but almost nothing else in service terms, and that shows in the separate specifications, torque values and diagnostic procedures given for each of them.

Known issues on the 1984 B6000. The federal record carries no recalls for this bus, and no owner complaints are logged with NHTSA. What remains is the manual's ordinary coverage, which is substantial given five engine choices. Each of the three gasoline V8s and both 8.2L diesels comes with procedures, specifications, torque values, wiring diagrams and diagnostics, and the cab forward chassis sections cover the frame, driveline, brakes, steering and body electrical circuits of the bus itself.
