This factory service and repair manual for the 1994 Chevrolet B7 adds a second gasoline V8 to the list, the naturally aspirated 7.0L OHV of 427 cubic inches, beside the 6.0L OHV V8 and the turbocharged 6.6L OHV inline-six diesel. All three go into the same cab forward school bus, designated B7T042. Because the diesel and the two gasoline engines share only the chassis, the manual keeps their specifications, torque values and diagnostic procedures apart and joins them again at the frame, driveline and electrical sections.

Known issues on the 1994 B7. The federal record holds no recall for this bus and no complaint from an owner. Coverage is what is left to judge, and it is even across the three engines: each has its own overhaul procedures, clearances, torque values and diagnostic routines. The chassis material behind them takes in the front axle and steering, the suspension and driveline, the brake system and the body wiring, the systems a bus like this accumulates hours on rather than miles.
