07 F350 XL Dually

[frdpwr]

Looking at buying a 07 F350 XL Dually with 150,000 miles. It has been a fleet vehicle and I have a bunch of service records on it. What should I be concerned with in the beginning if i buy it? I've read about egr valves and head gaskets but is all this really necessary?

Thanks

you really dont have to do anything to do...just be very meticulous about the maintance of the truck...those are things that can go wrong if not taken care of. What do you know about the history of the truck...keep researching and you get alot of answers...07 are usually ok..earlier years had issues like 04 05

"Meticulous" is the key word. And use the recommended fluids and filters although you may want to research the coolant. My dad bought a new '04 KR that he drove until he traded it in on a '12 a few months back. He never had a problem and the truck never exceeded a single service interval by even a mile.

I wouldn't buy a used 6.0L without having a way to watch the oil and coolant temps and from that, determining the health of the oil cooler (coolant flow passages plugged or not). I would also want to know how the FICM was performing with its convesrion of 12V to 48V. Lastly, I would put a pressure gauge on the degas bottle.
