I was changing my impellar housing the other day and I had the serpentine belt off of the motor when all of a sudden it looks like anti-freeze came out of the water pump on the front of the motor. I put it all back together, put the belt back on and ran the motor and it did not leak another drop. My question is is that normal when you take the belt off?

May be leaking out of the weep hole at the bottom of the water circulator?

Yes I think it was, is that normal?
