I waited years to buy my dream truck. The Ford F250 Diesel Super Duty Crew Cab. The last truck I would ever need to purchase. I just brought my truck in to the dealer, water pressure in the coolant reservoir. Service people with out looking under the hood told me what was wrong. The oil cooler and EGR cooler would need to be replaced. If not caught in time serious engine damage, head gaskets and worse $5,000 and worse. To all out there with a 6.0 diesel or thinking of buying one, consider the oil cooler a maintenance item at 50,000 miles. Have it replaced. From what I have read while learning whats wrong with my truck this is the major cause of problems on this engine. Pass it on
I love my truck. It fits me - I'm 6' 6" and I can wear a hat in the cab. The machine drives well, is easy to maneuver and park. This is my fourth F250 diesel - all my others were the 7.3L engine. My experience with the 6.0L diesel is that it underperforms the 7.3L both in power and economy. I was used to 14.5-15.5 mpg city and 18-20 mpg highway with the 7.3L. The best I've gotten with the 6.0L is 13.0 city and 15.0 highway. The 6.0L does not accelerate as well as the 7.3L did. I'm disappointed, especially as the price of diesel has escalated out of sight. There is a recall on the ECM and I hope that resolves the performance/economy problem.
As of Dec 2011, I have owned this truck for over six years. It was bought new and I haven't experienced any problems during this ownership. The truck is used to pull a 24ft boat, large horse/cattle trailer, and utility trailer. Excellent interior space for front and rear passengers, more than ample pulling power, smooth transmission shifting, dashboard layout is exceptional, and multiple positions for rear seat storage/hauling/seating. As some posts mentioned gas mileage - a heavy duty truck was designed for pulling and hauling which makes gas mileage secondary. My next truck will definitely be an F-250 Lariat.
Ford issued a recall for diesel emissions in late 2005, and blamed Ca Air Res Board for recall. NOT TRUE! Ford issued internal recall under state statute violation, and then recalibrated all 6.0 diesels. Performance dropped, turbos started blowing, mileage in the tank, continued issues with the EGR systems and oil leaks. THESE TRUCKS ARE TERRIBLE. I paid premium money for this truck, and am now in lemon law process and Ford is fighting me back and say nothing is wrong, but at the same time gave me 200K warranty on engine.. Yeah right. Piece of crap engine and NOT what I paid for and with this recall on problems they blame on CARB, as indicated by dealers, that is a flat out lie! Stay away!
