2018 Ford Flex Service and Repair Manual

This factory service and repair manual for the 2018 Ford Flex carries the four-door sport utility into its late years with Limited, SE and SEL trims and no change in the engine bay: a naturally aspirated 3.5L V6 (213 cu in) or a turbocharged V6 of the same size, both with dual overhead camshafts. Torque values and specifications for the two differ where the induction hardware does, and the wiring diagrams and diagnostics are written for the vehicle rather than for one engine, so both versions draw on the same electrical material.

• 3.5L V6 (213 cu in) — DOHC, turbocharged, gasoline

Known issues on the 2018 Flex. Three recalls appear on the federal record. One concerns rear suspension toe links that may fracture and cause a sudden change in handling. Another covers a rearview camera that can display a distorted or blank image. The third involves B-pillar door trim on the driver and front passenger doors that may detach while the vehicle is moving. Owners have filed 63 complaints with NHTSA, led by the structure, the electrical system and the suspension. Body trim fastening, suspension repair and camera circuit diagnostics all sit inside this manual.
