water pump

Hi, I have a water pump leak but its out of a hole thats moulded into the metal already!? Not sure if its an overflow hole or if something was meant to be in there? NOTE: The hole is on the underside of the pump. Underneath the spindle, if you were to look at it from the top. Can anyone...

had the car at pod but it just wouldn't run. started boiling after a few minutes. usually works fine :cry:
