Modern heater cores to fit Series IV Alpines or Tigers

Just a little blockage going on.
I'm probably going to do three or four and test and sell trade for needed parts . Barely 1/16 welding rod gets through the lower tubes . I'll rod then work a small flat brass through then maybe a little lime away . Not too many used distilled water back then.

Warren, soak that in "The Works" toilet bowl cleaner from the Dollar Store. Dilute 10/1. Let it soak 24 hours. It will be clean after a flush with the water hose.

Thanks Wayne have seen your Tidy bowl method and will give it a try . Gotta whole gallon of Zep lime away stuff to use up too.
