Your signature says you have a new oil cooler, did you flush prior to replacing the oil cooler? If you're concerned about contaminates in the system you can always do both. Be sure you flush the heater core, and radiator, then the engine with plenty of water. There was a video where the tech had the block plugs out, filled up the degas bottle with water, then started the engine giving it a couple good revs. The water was shooting out the block plugs and I am sure it was taking a lot of junk with it.
When you're done flushing with chemicals or tap water, reverse flush the oil cooler before your final flush with distilled water.

Blade, I think it might be. I'm getting high temps again, 220 -230. I think I might have screwed up when I replaced the oil cooler a few months ago. I finished the truck and realized that I forgot new coolant so I added just distilled water to the system and then had to leave out of town for a family emergency so the water sat in the truck for a week or so. Then when I got back it was about two weeks till I got a 50/50 mix in it. So I'm guessing that might have f#%$ it up. I'm not sure.

Oh Thats NOT Good straighht water will rust the system VERY VERY Fast
would have been better to leave it empty oh-well done deal now
Drain the coolant pull thermostat and do a few water flushes to get Coolant out
Get 2 qt VC-9 cooling system cleaner from FORD dump both in thermostat still out top off water and set the truck to HIgh Idel for 1-1.5hours in the driveway and let it clean away

Yes I do but you might have to Backflush the Oil Cooler Itself after the VC-9 treatment
Its the Oil Coolers that have 60-80-100K on them that usually are NOT savable the Junk is just to Packed in there with that amount of Mileage
But since yours is newer should be able to clean it definatly worth a Shot

If you didn't flush that well before the first oil cooler replacement, you're really going to have to do that now.

Read the document linked to above. It'll tell you everything you need to know to reverse flush the oil cooler as well as flush the system. If I were you, after each iteration of flushing, reverse flush the oil cooler with block plugs out. Also get the radiator and heater cores good as a lot of junk accumulates in there. I have a feeling that a LOT of people do not flush the radiator or heater cores and end up reclogging their oil coolers. Think of it this way, even if it doesn't work your cooling system will be prepared for the new oil cooler and DO NOT RUN JUST WATER in the system

I agree^^^
When I did this I had all the hoses apart so I took a Gareden hose and stuck it in the Heater core return side and reverse flushed it
I also stuck the garden hose in at the Thermostat Port and flushed there with block drains open and that was a Reverse Flush of the Block Basicaly
I went to great lengths to flush my system clean
So far it has Paid Off 15K since new oil cooler and deltas remain Good About the same as the Day the oil cooler was New
I also used Both the Gold and ELC with coolant filter and the ELC seems to last longer life out the filters. The filters with the Gold wasnt clogging up with casting sand or Junk either they was pretty clean nothing I could really see that would definatly clog it. The Gold seamed like it would leave a Slim coat on the coolant filter Media and it wouldnt flow. but with the ELC they are going further for shure no slime coat
The New Oil Cooler I have has Only had ELC in it FWIW

If you don't mind me asking what are the deltas on a new oil cooler?
I asked the question several years ago and it was never answered correctly.
I am not intending to hijack this thread, the question just seems to fit into the current topic.

2*-6* around town
6*-10* Freeway
If Im cruising along freeway and I start to coast down the OffRamp and maybe sit at the Light for 1min-2min the Oil Cooler will drop oil temp 3* in that short amount of time

mine is roughly the same, I never had any numbers to compare to thanks.
At 70 mph I generally have a 7-9 degree spread, 60 mph is 5-7, and 50 mph is 4-6 degree spread.
Our terrain is flat with the only elevation changes are overpasses. At approx. 85,000 mi. I had a thermostat stick open (-15f brrrrr) so I changed out the thermostat and flushed, switched coolant to John Deere Coolgard II at that time, also added coolant filter. I currently have 156,000 mi. and other than flushing the cooling system hasn't been touched.
Thanks again for the numbers to compare.

Yes sir just about the same
Cant beat that sounds like they cleaned your Block
Here is a Pic of what was in my oil cooler I changed
The screwdriver points to the Coolant Path/s then every other one is coolant path it all looked like casting sand to me
I had a 25-35* Spread no matter what and the only way the oil would cool down was to shut the truck OFF
So if your Oil Cooler can bring temps down running or after going over a Hill thats a GREAT Sign too
