2021 Ford Transit-350 Service and Repair Manual

This factory service and repair manual for the 2021 Ford Transit-350 lists eight body configurations across Base, PTV, XL and XLT trims, with the naturally aspirated flex-fuel 3.5L V6 and the turbocharged gasoline 3.5L V6 as the engine choices. From a three-door cargo van to a cab and chassis, all of them share the same front-end mechanical package, so the engine, transmission and brake procedures apply broadly while the wiring diagrams and body sections track what changes behind the cab.

Known issues on the 2021 Transit-350. Three recalls are attached to this model year. Ford recalled vans whose front passenger seat belt automatic locking retractor can deactivate early, which can leave a child restraint insufficiently secured. A van converter recalled units with an installed generator whose fuel hose can leak gasoline, and a mobility company recalled wheelchair restraint anchorage hardware. Owners have filed 31 complaints with NHTSA, spread across systems rather than concentrated in one. Restraint anchorage torque values, fuel line procedures and the wiring diagrams for installed equipment are the relevant sections here.
