That's exactly what I did with the rear windshield spray nozzle. It stopped spraying so I decided to take it apart to clean it, but I didn't think to disconnect it from below first and broke off the neck to the supply line. The plastic had become very brittle and I knew it would never epoxy back together as is, so I used a small hollow metal tube to join what was left of the neck with a piece of 1/8" dia. nylon hose coupler. It sprays now, but there's a small amount of leakage due to the fact that there was also a crack along the inside of the ring. Not a problem during the summer, but we'll see how it holds up during the freezing winter weather.
This might also work with radiator. I'm pretty sure most epoxy can handle those temps if allowed to cure properly. Depending on how bad a shape the piece that broke off is in, you might considering simply replacing it with a metal or nylon piece.
