This factory service and repair manual for the 2022 GMC Savana 4500 documents the base vehicle in its simplest form: one body style, the two-door cutaway; one trim, Base; one engine, a 6.6L naturally aspirated overhead-valve V8 of 401 cubic inches running gasoline.

Known issues on the 2022 Savana 4500. Nothing is on the federal record against this model year, no recall campaigns and no owner complaints logged with NHTSA. The manual therefore functions as a service reference and nothing more urgent than that. It carries the procedures and specifications for the 6.6L gasoline V8, the torque values for the fasteners those procedures call out, wiring diagrams for the circuits the cutaway leaves exposed at the back, and diagnostics for working a fault back to its origin.
