2008 Chevrolet C8500 Service and Repair Manual
This factory service and repair manual for the 2008 Chevrolet C8500 concerns a single-body truck, the medium conventional straight truck, built in two configurations, C8C042 and C8C064. The choice a buyer made was in the engine bay: a turbocharged 7.2L diesel inline-six of 441 cubic inches, a turbocharged 7.8L diesel inline-six of 475, or a naturally aspirated 8.1L gasoline V8 of 496 with overhead valves. One body and three engines mean the book opens out in the powertrain chapters and stays narrow everywhere else.

Known issues on the 2008 C8500. A single owner complaint is logged with NHTSA for this model year, and it falls under the engine. Engine work is the part of this manual with the most ground to cover, since three units share one chassis: mechanical and overhaul procedures, valve train and bearing specifications, injection and fuel delivery diagnostics for the two turbocharged diesels, fuel and control material for the gasoline V8, and torque values throughout. Cooling, driveline, brake, steering and wiring sections follow, each with its own diagrams and diagnostic steps.
