Coolant Issues

OK so recently i noticed that i have coolant leaking out of the drivers side somewhere, i believe my water pump is still good because i have the correct pressure BUT when i shut the car off i can hear the coolant boiling almost today i noticed that my over flow tank was filled to the brim so i am wondering could it be my thermostat?

I think it would be the waterpump, it will still have the right pressure, odds are is that the bearing is out leaking water out the bottom weep hole

problem is solved, it was the coolant sending tube, the o-rings were bad replaced them and it should be good now
