Agreed- the local shop charged me $85 just to pressure test and clean the radiator - and did a poor job at cleaning it - can’t imagine what they’d charge to replace the fittings.

I found the fittings that were in there previously - NPT into the radiator and male AN to the braids hose. I suppose I can try NPT to female AN fitting and maybe it’ll seal in the boogered up threads.

Anyone know what size NPT that would be? The correct line fitting is 1/2x20
