Official summary
Some 2020-2026 Aviator/Explorer/F-150/Bronco/Ranger vehicles equipped with a 2.7L or 3.0L (non-diesel) engine may need the front engine cover removed and reinstalled for various reasons. The Workshop Manual (WSM), Section 303-01 Engine > Removal and Installation > Engine Front Cover service procedure has been updated to include a new essential special service tool (ESST) guide pin alignment tool (303-1790) that is used to align the engine front cover to the engine block, preventing the O-ring seal on the engine oil galley feed tube from getting damaged during installation.

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.
