2010 Ford Flex Service and Repair Manual

This factory service and repair manual for the 2010 Ford Flex adds a second powerplant to the book: beside the naturally aspirated 3.5L V6 (213 cu in) there is now a turbocharged V6 of the same displacement, both dual-overhead-cam gasoline engines. The four-door sport utility was again offered as Limited, SE and SEL. Charge-air plumbing and its own control strategy give the turbocharged car sections of its own, while the chassis, body and interior material applies to every version of the vehicle equally.

Known issues on the 2010 Flex. A single recall stands on the federal record here, concerning a driver frontal air bag that may inflate improperly during second-stage deployment in a high-speed crash, with a corresponding increase in injury risk. Owners have filed 139 complaints with NHTSA, the largest share about the steering, followed by the engine and the service brakes. Those three areas map onto the steering, engine and brake chapters of the manual, where the relevant procedures, specifications, torque values and diagnostics are set out.
