First coolant filter change

First coolant filter change
Last July I installed a coolant filter kit from dieselsite, did a full flush and switched to Rotella Red with RMI-25 instead of SCAs.
I went on an 5k mile trip and last week I changed the 1st filter out (about 6k miles total). Thought all y'all might be interested in seeing what the insides looked like.

interesting read, RMI is supposed to clean out crud and looks like it did on yours

18 months ago OP had 185k on motor, my guess it cleaned out a lot of stuff that built up over the years and maybe should have checked that filter sooner

That's an understatement. I should have had a filter on it long ago also. The coolant prior to change was not that old, I flushed and filled when I bought it at 170k (I think ford recommends every 30K). Flushed it again when I changed it 6K ago. It was still dirtier than I expected but I guess the RMI-25 is doing it's job and cleaning things up quite well. From what I've read some of that sludge is it cleaning up the SCA buildup as well.
The RMI literature recommended changing the filter 3 times in the first year and annually after that. Since the average soul drives 12k/yr I equated that to changing it every 4k the 1st 3 times. Live and learn.
Needless to say I have a lot less crap in my system then I did one filter ago and I'm sure to have even less in another filter from now.
It's all been educational.
