Service bulletin SSM 51014

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

The electronic parts catalog for the 2021-2022 Bronco equipped with a 2.7L GTDI engine had the incorrect engine oil dipstick assigned. This problem only existed for a few months and has since been corrected. The incorrect dipstick that showed in the catalog was SPN: MB3Z-6750-B/F (EPN: MB3E-6750-BB/BC). The 'MB3Z' dipstick (EPN: 'MB3E') is ONLY designed for use on the 2022 Bronco Raptor which is equipped with a 3.0L GTDI engine. The correct engine oil dipstick for the 2021-2022 Bronco 2.7L GTDI engine is SPN: FT4Z-6750-B/C (EPN: FT4E-6750-BF/BG).
