Coolant Filter on Gas Motors

I've got a 4.6L in my 2000 Lincoln Town Car. Spent the morning saturday flushing the cooling system. I got 159k miles on this car and I don't think the T-stat or the coolant had ever been changed. So I drained, flushed, filled, and replaced the Tstat and degas cap.

Drained, flushed with tap water, drained, flushed with tap water... flushed and flushed till it ran clear (yes I captured my old coolant for disposal).. then I did about three flushes of distilled water... thought it was all good.

Filled with Advanced Auto Part's ELC coolant..

Everything is great now. The new 195 degree thermostat works like a charm... no leaks, everything is great...

Except, I still see particulates floating in my new coolant... ARGHHH...I think its scale from the old coolant... (IDK)

Anyway... I've been thinking about adding a coolant filter to this motor.

I've done some googling and know that I would need a coolant filter without the SCA additives that the diesel guys run. Part of me says to forget about the particulates and be satisfied.. But... the other part of me says to do everything I can to keep the coolant clean and free for particulates. I have even read about some running a oil filter as a coolant filter on gas motors. Not sure I would do that though.

So, any of you have any thoughts on adding a coolant bypass filtration system to my gas engine. I know its overkill.. but still.. I think I would feel better with it on there.

Thanks!
