Iv owned my taurus for little over a month, when i bought the car it needed a new water pump. After getting that replaced, the car had a complete oil change, and now i have another problem. I have not been driving the car because the engine keeps showing that there is NO coolant running through it.

I filled the anitfreeze resevoir, but the antifreeze is not circulating. I have been told that its a popped freeze plug?? How can i get this fixed?? & how much is it going to cost me..
HELP APPRECIATED!!
