Official summary
Some 2015-2019 Transit vehicles built on or before 31-Dec-2018 and some 2017-2018 E-Series vehicles equipped with a 6.8L engine built on or before 16-Jul-2018 using the Motorcraft Orange coolant may exhibit an engine or transmission overheat concern. This condition may be due to deposits from the engine coolant becoming trapped in the radiator preventing coolant flow. To correct the condition, flush the cooling system, replace the radiator and fill with Motocraft Yellow coolant.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
