Not a tech but I just had the same issue with mine and it was the oil cooler. Deleted the EGR cooler, rebuilt the oil cooler, and did a radiator flush. I don't know if its common but my oil cooler had busted and was mixing water and oil and whatever else was in the cooling system. Took me 12 attempts at flushing it all out. I wonder if the ford house flushed your radiator system after installing the oil cooler. The ford house in Houston that replaced the oil cooler before i purchased mine didn't and thats why 3 weeks into owning the truck with maybe 12k miles i had to do it myself. Like I said though I am not a tech or a mechanic just a monkey with a wrench passing on what happened with mine. Good luck with it though I know its a pain in the arse!
