Additional Notes
- Across all listed configurations, the brake fluid reservoir level is specified as between the minimum and maximum marks rather than a fixed volume. This is standard for hydraulic brake system service checks, where the reservoir level is inspected and topped off as needed rather than measured by a precise fill quantity.
- The Ford Flex 3.5 EcoBoost V6 AWD configurations from 2010-2013 carry no fluid change interval in the specifications, meaning only a level check between the min and max marks is indicated for those model years under normal use conditions.
- Starting with the 2013-2016 EcoBoost V6 AWD configuration, a 24-month brake fluid change interval appears under normal use conditions. The same 24-month interval carries forward into the 2016-2017 configuration, making it consistent across that span of model years.
- The 2017-2019 EcoBoost V6 AWD configuration shifts the brake fluid change interval from 24 months to 36 months under normal use conditions. A 36-month interval is a longer service cycle, reflecting a change in the specified maintenance schedule relative to earlier model years.
- The naturally aspirated Flex 3.5 V6 AWD, listed for 2018-2019, shares the 36-month brake fluid change interval specified for the 2017-2019 EcoBoost V6 AWD. Both configurations align on the same interval and the same reservoir level specification under normal use conditions.
