I have a 2010 mazda3 and ive never had any issues out of it at all and today out of nowhere it starts overheating and pouring coolant out of a little black box thing is where it looks like its coming from. I have no idea what it is or how or what to replace. Help!!!

Yes never had an issue before now. Its spewing water/coolant from something directly to the right of the engine. There's a bunch of hoses there and a metal thing screwed onto a black plastic thing.
