2002 Chevrolet T6500 Service and Repair Manual

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.
