Engine oil cooler

I am starting to see some signs that my oil cooler is leaking oil. I have a 2000 f350 CCLB with about 275K miles. I’m hoping to wait until the weather cools a little to do the work on it but just trying to get a gameplan together. Is it recommended to replace the cooler and the o-rings/gaskets? Or can you just get away with just o-rings/gaskets? And if I do need to replace the cooler, has anyone had good results with an aftermarket part or is everyone using the ford part. I haven’t noticed any oil in my degas bottle nor have I seen any coolant in my oil changes if that has any relevance. Thanks for any insight you can provide

I did the cooler on my f450 and it was a pita, although alot of folks on here say its not to bad.... make sure you get the oem orings, i got some from a Ford dealer on ebay

I replaced my cooler and orings a year ago with dorman. Within 4 months it was leaking again. Finally 2 weeks ago replaced the orings with motorcraft from Riffraff. No leaks so far and hopefully stays that way.

Oh, and the first time around I watched YouTube videos of guys leaving the front mount attached and just removing the rear mount. Didn't go so well for me, lost a front orings up where I couldn't see while reinstalling. That led to an extensive (expensive) period of flushing the oil and cooling systems. After that I removed both ends and assembled the whole thing on the workbench, which worked much better.
