1998 Chevrolet T6500 Service and Repair Manual

This factory service and repair manual for the 1998 Chevrolet T6500 has three engines to sort through rather than two. The gasoline 6.0L overhead-valve V8 of 366 cubic inches carries over, and it is joined by two turbocharged overhead-valve diesel inline-sixes, a 7.2L of 441 cubic inches and a 6.6L of 403 cubic inches. All three go into the same low tilt cab straight truck, built as F6B042, and the manual keeps their mechanical, fuel and diagnostic material separate so no specification is applied to the wrong engine.

Known issues on the 1998 T6500. For a truck bought to work, the emphasis falls on service quality, which is what factory procedures protect: correct disassembly and reassembly sequences, clearances and running specifications for all three engines, injection and induction diagnostics for the two turbodiesels, the torque value for each fastener at the point it is tightened, and wiring diagrams that let an electrical fault be found rather than guessed at.
