This factory service and repair manual for the 2010 Chevrolet Express 4500 documents a cab-and-chassis cutaway offered in Base form only, with two engines behind the firewall: a turbocharged 6.6L diesel V8 of 403 cubic inches and a 6.0L V8 of 364 built to run flex-fuel. The flex-fuel calibration matters in service, because fuel composition sensing and the materials in the delivery system differ from a gasoline-only setup, and the manual keeps those procedures distinct from one another.

Known issues on the 2010 Express 4500. The federal record carries no recalls and no owner complaints for this chassis. That leaves the manual to be judged on coverage: diesel injection and emissions work, flex-fuel delivery and engine control diagnosis, automatic transmission and rear axle overhaul, front suspension and steering specifications, hydraulic and antilock brake service, and the cab wiring diagrams a body builder wants in hand before cutting into anything.
