Are the diesel coolant filters more of a chemical/ionic filter and not so much a physical filter media?
I might just do a yearly flush and live with it. It doesn’t seem to hurt anything other than my pride. Truck runs cool other than on the hottest days when not moving at a long light.
The power washer thing probably needs done, but I’d likely wait until I’m ready to do the 216 water pump adapter thing. Running a short shaft 235 pump now and it works plenty good enough for me.
I might also do the combustion gas test thing just for a little peace of mind. I just don’t have any milky oil, no overheating, no steam-cleaned plugs (last I looked).
