SSM 48139 - 2011-2014 F-Super Duty - 6.7L - Lack Of Power/High EOT
Under Heavy Load - Remanufactured Engine
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.
