This factory service and repair manual for the 2005 GMC T6500 is a single-engine, single-designation book: the 7.8L turbocharged inline-six diesel of 475 cubic inches, in the T6F042 chassis. That focus shows in the depth of the engine coverage, and the same treatment carries through the transmission and driveline, the service and parking brake systems, the steering and suspension, the chassis and the body, each with its own procedures, specifications, torque values, wiring diagrams and diagnostics.

Known issues on the 2005 T6500. One owner complaint is logged with NHTSA against this model year, and it concerns the parking brake. That is a system a medium-duty truck cannot afford to have working approximately, and the manual covers its adjustment, service and diagnostic checks along with the specifications and torque values that go with them. The rest of the book follows the same pattern through the 7.8L turbocharged diesel six, the driveline, the service brakes, the steering and the chassis wiring.
