This factory service and repair manual for the 2001 GMC T7500 is written around two turbocharged diesels of similar layout but different size — a 7.2L overhead-valve inline-six of 441 cubic inches and a 7.8L inline-six of 475 cubic inches — in the F7B042 configuration that is the only one listed for the year. Because both are inline-sixes, much of the chassis and driveline coverage is shared, while the injection, air handling and cooling specifications split by displacement. Torque values, wiring diagrams and diagnostic routines follow the same division.
