2008-2010 F-Super Duty

This article supersedes TSB 08-19-5 to update the vehicle model years.


Some 2008-2010 F-Super Duty 250-550 vehicles equipped with a 6.4L diesel engine may exhibit a random engine ticking / tapping noise that is most noticeable when engine coolant temperature is 185 °F (85 °C) or higher and from base idle to approximately 1500 RPM. Some customers may complain that this noise becomes more evident after 3000-5000 miles have accumulated on the vehicle or after an engine oil change.
