2006 Chevrolet C8500 Service and Repair Manual

This factory service and repair manual for the 2006 Chevrolet C8500 has five configurations to keep apart — C8C042, C8C064, C8E042, C8V042 and C8V064 — spread over a straight truck cutaway, a medium conventional straight truck and a four-door crew cab straight truck. The engines behind them are a turbocharged 7.8L diesel inline-six of 475 cubic inches, a turbocharged 7.2L diesel inline-six of 441, and a naturally aspirated overhead-valve 8.1L gasoline V8 of 496. That spread is why the chassis and wiring sections are written to cover every version rather than one.

Known issues on the 2006 C8500. One recall is on the federal record for this model year. It concerns an air brake valve whose internal check valve may not seat properly; air leaking past it can delay the spring brakes from applying once the dash button is pulled, and a truck that appears parked may roll. The single owner complaint logged with NHTSA falls under engine and engine cooling. Air brake and spring brake service, and cooling system work for all three engines, are covered here with the specifications and torque values each job calls for.
