This factory service and repair manual for the 2011 GMC Savana 4500 has a narrow brief and covers it fully: one body style, the two-door cutaway, and one trim, Base. Under the hood the choice was between a 6.6L turbocharged diesel V8, 403 cubic inches of it, and a 6.0L naturally aspirated V8 of 364 running flex fuel. Both are overhead-valve engines, and both are documented here along with the cutaway chassis and the wiring an upfitter has to work around when the rear body goes on.

Known issues on the 2011 Savana 4500. This model year carries a clean federal record, with no recall campaigns and no owner complaints logged with NHTSA. That is a good position for a chassis that spends its working life under somebody else's bodywork, and it leaves the manual to supply what a shop actually asks for: engine procedures and specifications for the 6.6L diesel and the flex-fuel 6.0L, torque values for the fasteners those jobs involve, and wiring diagrams for the base-vehicle circuits.
