So I have a coolant leak, leaking onto the top of my transmission. It is coming from the bottom of the aux water pump.

I checked the two hoses leading into the pump and they seem to not have any visible cracks. The hoseclamps were tight.

This is the aux water pump that I took out, how do you tell if it is leaking? Does there have to be an obvious crack or not? Somehow a fair bit of coolant drips out of the bottom of it everytime I drive my car. Should I just buy a new one? I can't see where it would be leaking from though...

Edit: now I think of it, I have definitely isolated the problem to either the pump itself or the bottom hose, it never happened from the hose the comes out the side of it. I am tempted to just buy a new damn pump but will wait to hear peoples opinions.
