Water pump replacement issues?

So my car has been dumping water for awhile, inspected hoses, realized it was coming from the water pump. Replaced it, eat enough I though, only 10 bolts and the new one was on. I take it for a test drive and there's a very loud screeching sound, especially when I accelerate. Now I know that's the belt, is also smoking now. Water pump isn't leaking but what's this about?? I assumed I messed up the belt routing but everything seems correct? It's almost like maybe I tightened the pulley too much? Like maybe like it's not spinning?? Please help.
