This factory service and repair manual for the 2009 GMC T7500 closes out the model with the same single power plant it ended on, a turbocharged 7.8L inline-six diesel of 475 cubic inches, in the T7F042 configuration. Coverage is arranged by system: engine mechanical, fuel delivery, air handling, cooling, lubrication, driveline, brakes and chassis. Each of those carries its own removal and installation procedures, published specifications and torque values, and each is supported by wiring diagrams and the diagnostic sequences that go with the circuits involved.
Engines covered

Trims covered

Known issues on the 2009 T7500. No recalls are recorded federally for this truck and NHTSA lists no owner complaints against it. A clean sheet is welcome but it is not a service history, and a truck in constant service still wears bearings, hoses and brake friction the same way. What the manual offers against that is specific: procedures for the 7.8L turbocharged diesel and its accessories, published specifications and torque values, and diagnostics backed by chassis wiring diagrams.
