6.7L – Lack Of Power/High EOT Under Heavy Load – Remanufactured Engine – 2011-2014 Ford F-Super Duty

NHTSA ID Number: 10164598

Manufacturer Communication Number: SSM 48139

Summary

Some remanufactured 6.7L diesel engines recently installed in 2011-2014 F-Super Duty vehicles may exhibit a lack of power with engine oil temperature (EOT) exceeding 125°C (257°F) under loads. This may also be accompanied by “REDUCED ENGINE POWER” being displayed in the message center and the coolant temperature gauge indicating “H”. This symptom may be due to a missing metering cup plug in the upper oil pan causing reduced oil flow through the oil cooler. Remanufactured engines built on 1-Mar-2019 and through 13-May-2019 may be affected. If a vehicle exhibits this concern, use the Report a Vehicle Concern link at the bottom of the OASIS tab and submit a report. Include the engine serial number and engine build date in the report. The dealership may be contacted for further details and possible repair direction.
