Engine is overheating and coolant is just spewing out all over the engine. Also, now as I pour water into the radiator, it just flows right back out somewhere else. guessing the water pump.

It overheats an the belt comes off
Something very similar was happening to me. Just driving last summer when my low coolant light came on. Could not figure out why until I had it confirmed I had a bad water pump leak. Simple fix was to replace the water pump (cost me 35$ for the part). But watch out, the coolant that was leaking started to mess up the serpentine belt and I had to get that replaced as well otherwise it completely destroy it.

Coolant has been leaking for 2 years. It is cheeper to buy more coolant than to repair.

Water pump gasket had worn out and was leaking coolant causing the engine to overheat. I removed the water pump and replaced with a new one from auto zone. It was a hassle getting to some of the bolts and the serpentine belt had to be removed for access.
