1999 Chevrolet T6500 Service and Repair Manual

This factory service and repair manual for the 1999 Chevrolet T6500 drops the gasoline option and leaves two turbocharged diesel inline-sixes in the F6B042 straight truck with its low tilt cab: a 7.2L overhead-valve engine of 441 cubic inches and a larger 7.8L of 475 cubic inches. Both are compression ignition, so the fuel injection, air induction, cooling and lubrication material dominates the engine chapters, and the specifications and torque values are given separately for each of the two displacements.
