Use a piece of brake line that fits in the hole with a bit of epoxy on that. It will both seal and reinforce the broken piece. Or just go the old school route and just send it, though this radiator doesnt have the upper tank volume with that in mind.
Exactly just glue a metal pipe in, use a drill to make sure you didn’t block off the pipe once the glue has set then glue the broken piece back on over the pipe.
Use it until the radiator cracks or you have money to buy a new radiator
