This factory service and repair manual for the 2019 GMC Savana 4500 covers one engine in three fuel configurations: the 6.0L naturally aspirated overhead-valve V8 of 364 cubic inches, built for gasoline, compressed natural gas or flex fuel. The vehicle itself is listed once, a two-door cutaway in Base trim, so the fuel setup is the only real fork in the road. Delivery hardware, specifications and diagnostics differ across those three, and the manual treats them separately.

Known issues on the 2019 Savana 4500. Nothing has been recalled on this model year and no owner has complained about it to NHTSA. The manual's job is the day-to-day work, and the part worth having is the fuel-configuration detail. A compressed natural gas 6.0L has delivery hardware and diagnostic checks that a gasoline or flex-fuel one does not, and getting that wrong wastes an afternoon. Procedures, specifications, torque values and wiring diagrams are given for the version actually in front of you.
