Help EOT High

I changed my oil cooler about 2 months ago everything ran fine 15 degree split from water to oil temp on the edge read out and from everything i have read that is what you want. Took a trip about 2 weeks ago to the coast pulling my 25 ft toy hauler and the oil temp got up to 235 and now running around town it runs the same not towing any suggestion?

Well, let me be more specific. The proper flush utilizes 2 different cooling system cleaning chemicals. One of which dissolves the coating that the old coolant applied to the walls of your cooling system, and the other removes the rust scale. They must be done separately and after each, the system must be flushed with distilled water until the water coming out of the block is clean and clear.
If you "skipped" either one of the chemical agent flushes, the material those chemicals were designed to remove is what has plugged your new oil cooler.
Check the second link in my signature line. You MIGHT be able to reverse flush SOME of that material out. It will take alot of work and dedication as well as alot of your time and some money, but in the end it will be cheaper than paying someone to do this job again.

What did you flush it with? Ford does say to use one of those chemicals, their name for it is VC-9, which removes rust scale.

Ok, so that tells me that the chemical flushes were skipped. That stuff is JUNK for a diesel engine, and it certainly was not enough. That stuff you used was formulated for a GAS engine and not for a cooling system of the capacity that we have (which is 7 gallons).
Download the document, use BOTH chemical flushes and attempt the reverse flushing. The reverse flush requires the investment of some additional parts, but if it can save your oil cooler, it will be worth it.
At the end of the flushing install a CONCENTRATED (not the 50/50 premix) ELC coolant that is CAT EC-1 rated. You can find this coolant at International truck dealers under the "Fleetrite" name. There is also a ZEREX ELC that you can get at NAPA (probably have to order it).
If after all the flushing, you still have a high oil temp, your recent oil cooler will have to be replaced again. The good news is that you will have all the contaminants out of your cooling system this time. Your next oil cooler should last a long time.
