03 2.3l Radiator Leak

[Zeisan]

I've just recently noticed a radiator leak in my 2003 2.3l Ranger. The leak appears to be coming from in between the metal and plastic parts of the radiator. I saw coolant leaking out as far up as the return inlet along with some bubbling. I was wondering what would be the best way to fix this issue without replacing the radiator? Would it be better to replace it? Thanks for any help you can give.
