This factory service and repair manual for the 2000 Chevrolet B7 lists the turbocharged 7.2L OHV inline-six diesel and the naturally aspirated 7.4L OHV gasoline V8 as the year's two engines, in the cab forward school bus designated B7T042. Everything about them differs in service, how they start, how fuel reaches the cylinders, how faults present themselves, so the manual keeps them in separate chapters, then brings the bus back together for the chassis, brake, steering, suspension and electrical work.

Known issues on the 2000 B7. No recall touches this model year, and NHTSA lists no owner complaint. That makes the manual purely a working document. It provides overhaul and adjustment procedures for both engines with their specifications and torque values, chassis coverage from the front axle through the driveline to the brakes, and electrical material that combines wiring diagrams with diagnostic sequences, so a fault in the starting, charging or lighting circuits can be traced to the connector rather than guessed at.
