95 grand am coolant problem

I have a 95 grand am 3.1 v6 and a week ago i took a turn a little hard. when i got home i noticed all my coolant was leaking out so after it cooled down i took a look at the engine and noticed that the plug in the bottem of the overflow tank had fallen out so i put it back in and thought i was done. After another drive i noticed steam comming from the engine and a coolant smell. (i wish i knew what to call it but i dont-->) a round metal "object" driven by a belt on the left side of the engine lets steam out and leaks coolant, it seems loose. What can i do to fix it.
i really need help and im low on cash

Welcome to AF !

Almost sounds like the water pump you are describing, but I'm not real sure either.

yea its definately the water pump, thanks for the picture. when the engine is running the "cap" on the water pump wiggles back and forth.
