OTW Back-flush

1281 Views 5 Replies 4 Participants Last post by  woodnthings8
Does anybody have any suggestions on back flushing my OTW portion of my radiator? I know some have said they have just used clean ATF fluid, a friend suggested using mineral spirits to clean up the gunk and help clear it out of there. I know that stuff is flammable and I would have to flush it back out with ATF fluid again. Any other product suggestions? Thanks
