Since I've had access to a few different oil coolers lately, I decided to take some comparison shots. Maybe this will help a little bit.
Background:
Dorman- Used, came out of an excursion with 170k miles, I don't know when it was replaced. Seals looked pretty bad and I had to hammer it out of the cover and damage the cooler to get it out.
Ford/Navistar- Used, Purchased from a dealer a few years ago, worked well... until my engine siezed. Unrelated.
DieselSite- New, purchased a month ago when I got the ford/china one. I wanted to keep it on the shelf. I ended up putting it in the excursion engine so we'll see how it holds up.
Ford/China- Purchased new from dealer a month or so ago. Installed in my truck, have about 1000miles on it so far, mostly towing my 10k trailer. Issues early on, but that was my fault for not flushing the system properly. After backflush its running pretty decent temps. Not great but decent. Deltas get pretty wild but my EOT stays less than 220 towing 10k flat and less than 230 pulling a grade. I think my radiator has something to do with it too, its a cheap aftermarket one.
My conclusion, I'd rather run a dieselsite cooler than the new ford cooler. Looks better all around, even packaged better. (I am not sponsors by dieselsite, I actually had a negative experience with them recently).
Anyways, on to the photos.
The bottom stamping imprints (donut shape) appear similar between the dorman and ford/china... suspicious.
It's not really legible, but I did go through with red numbers and mark each plate to prove the count. Its hard to count by hand after about 10 plates in they all look the same and I get mixed up. The red numbers prove it though.
Hope this helps anyone trying to decide on a cooler.
Anyone heard reports of this new style failing? Some of the comments on that video suggest it may be a dorman part. I installed one of these new style coolers in my truck, no issues of oil cooler's fault yet but it's only been a couple months. I did order a Dieselsite cooler to have on the shelf just in case.

I think that's the problem...not enough data out there because it's a relatively new change. Only time will tell whether or not these are a quality part.
Going to be a lot of external coolers sold. And more people looking for ways to clean the old coolers.
I was reading this on the org as well.
I considered the oil to air, several yrs ago, but being in winter / salt etc I wasn’t sure I wanted to do that. Still not sure I like the idea for some reason.
Is there a way to clean an original cooler properly? I’ve never looked into it.
I had done extensive flushing with the usual chemicals for a longer time than most would be comfortable back around 2010 after running G05. Cutting the oil cooler apart, he helped some, but not enough. ZMANN, an admin on several sites, says Dawn with Cascade does it, but I can't confirm that.
The new engine's oil cooler clogged on me with an ELC, but when cutting it apart, it had debris in the intake port. Those could have been cleared with the current practice of water and compressed air backflushing.
I’ve got chunks of cut up coolers that were clogged with G05. I been thinking of setting up a group of different things to see how well they may dissolve the mess.
