haha its not the fan
it goes into regeneration that is the exhaust it is wide open cleaning the exhaust filter that is why it is so loud, that is not the clutch fan.
Next time it does it look at the information bar it will say cleaning exhaust filter. I just bought another 6.4 . I have my 2008 F-550 and now I have a 2010 F-350. Needed a new truck and didn't want to be the test dummy for the 2011.
