Leaking lower radiator hose at water pump end
I noticed that my car was leaking coolant where the lower radiator hose connects to the water pump. The coolant seems to seep around the edge of the connection and drips down the hose. I replaced the hose today and it's still doing this... could there be a crack or something on the water pump fitting that would cause this?

It's leaking from underneath the water pump from the weep hole. See my post on this board for a picture of the water pump I just replaced. the post is called "pictures of my stewart waterpump install.

Yes, you have to replace the waterpump. Coolant leaks from that hole to tell you that the water pump shaft seals are bad.
