2020 Ford F-450 Super Duty Service and Repair Manual

This factory service and repair manual for the 2020 Ford F-450 Super Duty marks a change of gasoline engine. The 445 cubic inch 7.3L V8, naturally aspirated and overhead-valve, is new to the list and works alongside the turbocharged 6.7L V8 diesel. Five bodies appear, from the two-door standard cab pickup through the four-door crew cab pickup and three chassis cabs, with six trims above them. A gasoline engine this new brings its own torque values, specifications, wiring diagrams and diagnostics, and they are set out here by system.

Known issues on the 2020 F-450 Super Duty. One recall is on federal record for this model year. It covers front seat backs whose recliner mechanism may have been improperly assembled, leaving reduced strength so that the seat may not restrain an occupant properly in a crash. Owners have filed 24 complaints with NHTSA, and those land elsewhere: the fuel system first, then the power train and the electrical system. That is a familiar pattern for a working truck, and it maps onto the fuel delivery specifications, driveline procedures and wiring diagrams this manual sets out for the 6.7L diesel and the 7.3L gasoline V8.
