Mainly it filters rust particles. The engine sat for 27 years. So when i took the heads off the coolant channels where packed with rust and sludge. I ended up filling the block with CLR and letting it soak for a few days and then flushed and used wire brushes to remove as much as i could. Had to also use shop vac to suck out rust sludge that would not flush out. After about a day of that i got good clear water flowing through. I got my radiator from championradiators.com and saw the filter so figured id get it as a little piece of insurance for $80.
