2016 GMC Savana 4500 Service and Repair Manual

This factory service and repair manual for the 2016 GMC Savana 4500 documents a 6.0L overhead-valve V8 that could leave the plant configured for gasoline, compressed natural gas or flex fuel, plus a turbocharged 6.6L diesel V8 of 403 cubic inches. Body style and trim are single entries, a two-door cutaway in Base specification, so the whole of the variation this manual handles is in fuel and combustion, and it separates the figures accordingly rather than pooling them.

Known issues on the 2016 Savana 4500. The manual's work is ordinary service, and the useful part is the fuel-configuration detail. A gasoline 6.0L, a compressed natural gas 6.0L and a flex-fuel 6.0L are not interchangeable in their delivery hardware or their diagnostics, and the diesel is different again. Procedures, specifications, torque values and wiring diagrams are given for each, on the cutaway chassis as delivered.
