This factory service and repair manual for the 2002 Chevrolet T6500 continues the pairing of a 7.2L overhead-valve inline-six of 441 cubic inches with a 7.8L inline-six of 475 cubic inches, both turbocharged diesels, in a straight truck with a low tilt cab built as F6B042. A tilt cab changes how service is approached, since major engine access begins with the cab rather than the hood, and the procedures, specifications, torque values, wiring diagrams and diagnostics are arranged for a truck that is opened that way.

Known issues on the 2002 T6500. No recall and no owner complaint appears on the federal record for this model year. On a working truck a clean record is worth less than a correct procedure, and the correct procedures are what this manual holds: engine disassembly and assembly steps with clearances and service limits for both diesels, injection and turbocharger induction diagnostics, cooling and lubrication specifications, torque figures given where each fastener is installed, and wiring diagrams that carry each circuit through its connectors, splices and grounds.
