Bought 2005 f-350 in 2009 with 18000 miles. 6.0 diesel .egr cooler and head gaskets went bad with 40925 miles. Called ford and they said so sorry. Well $6600 later out of my pocket and very upset with ford. Thousands of trucks have had the same problem and ford gives no help to anybody. Spent 30k on this truck, put 22000 miles on it and all these problems.for all people looking at either a 6.0 or a 6.4 DO NOT BUY!!!! Never buying a ford again.
