Installed a Dieselsite coolant filter at 10,000 miles, 35K now. Changed the first filter at 1,000 miles, tore it open and it had about a tablespoon full of sand and some sludge that was like toothpaste. Changed the 2nd filter after 3,000 miles and got about a teaspoonful of sand and more sludge. I've changed it twice since then but didn't tear them open. The Degas bottle doesn't have the 'coating' crud inside anymore either.

After seeing the sand and sludge it filtered out of the cooling system I definitely recommend the coolant filter.
