This factory service and repair manual for the 2002 Chevrolet B7 documents a cab forward school bus, designation B7T042, with the turbocharged 7.2L OHV inline-six diesel and the naturally aspirated 8.1L OHV V8 gasoline engine. Its arrangement is practical: engine chapters first, each complete with its own specifications and torque values, then the transmission and driveline, then the brakes, steering and suspension, then the body and its electrical circuits, so a repair can be followed from diagnosis to final tightening in one place.
