id flush the piss out of it and call it good.
Even if it has the sludge that was in my rad? I flushed the eff out of my radiator too and the nasty diarrhea sludge never came out, its heavy and just seems to settle in the bottom, i have my old rad upside down right now and the sludge just keeps running out, i really wonder what those flushes did..is there anyway i could stick wire brush/bore cleaner into the core kinda like cleaning a rifle barrel. would this work?
