Service bulletin SSM 55228

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's 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.

Other bulletins for the same vehicles and component
SSM 552172026-10-06. Service bulletin. Some 2020-2024 Explorer/Aviator vehicles equipped with 3.0L EcoBoost/hybrid engine may exhibit blue or black exhaust smoke on startup for the first 5 minutes after an overnight cold soak with no illuminated malfunction indicator lamp (MIL) or powertrain diagnostic trouble codes (DTCs) present. This may be due to engine oil breaching the dynamic oil seals separating the bearing core from the turbine housing in the left side turbocharger assembly. There is a new, updated left side turbocharger oil supply tube equipped with an internal check valve to prevent the engine oil from entering turbine housing after the engine is off. Replace the existing left side turbocharger oil supply tube with the updated service part that includes the check valve (service part# L1MZ-9T516-B) or latest level part. Refer to the Workshop Manual (WSM), Section 303-04 Fuel Charging and Controls - Turbocharger > Removal and Installation > Turbocharger Oil Supply Tube LH. For claiming, use causal part 9T516 and labor operation code 9440AL.
