Aluminum Radiators in 2024

Before I completely forget, I measured the overflow hose nipple diameter with calipers: 0.31" better known as 5/16".... not the 3/8" it should be. The nipple is a threaded version that I hope to change easily, and unless they glued it in I think we're ok.

I forget what size the original nipple was but it wasn't what one would expect for a 3/8" nipple. Like I said I had to use a threaded reducer cause I didn't feel froggy enough to bore the neck out to the right size & tap. I'll suggest boring out the reducer for better flow. I know the OE rad nipples had better flow than any screw on one.
