Coolant would start to leak out under the belt

I'm curious what an expert would suggest how I should go about it and what parts I may need. Low budget.

I have a 97 Buick Century and for the past month after driving my car for 10 minutes or more my coolant would start to leak out under the belt. So I was putting water in every time before I'd get into the car. Well on my way to work one day, my engine started running hot, one line above the red it never went into the red but got awfully close. I managed to get to work noticed my engine steaming a bit but I had to get into work so I didn't take a real look at it. Got off work got back to my car and filled it with water.

Was going to check my oil as well so I drove over to Walmart and I checked it in the parking lot it had plenty still and looked fine. So after shopping I took off. On my way back home the engine went back to running hot 2 lines above the red. So I decided I was going to stop in at a friends and let it cool off and get more water. Well I drove a couple miles more and the temp started to drop and stayed at the halfway line. Well right before my turn (right) I felt something only I could describe as my wheel begin to wobble, I get into my turn lane and then as I go to make my turn my power steering was gone, completed the turn and went to speed up and there was nothing, no go, no revving. Pulled over the best I could. As I placed it in park the temp gauge, which remind you was at half, all of a sudden jumped into the red.

Turned off the car got out and the engine was steaming pretty bad. Decided to walk to my friends and let it cool off and attend to it later. Next day I was able to drive it from there to my house (5 miles away) still ran relatively warm and there was a weird noise that had never been there before. Just trying to figure out if it is the water pump, the water pump and other things. Just confused and would like heads up before I go and start anything on it.
