I bought the pump from mac's about a year ago. I tried to call them but their customer service leaves a lot to be desired...
I was curious enough to press it apart. The bearings are all sealed and it has a mechanical seal that is spring loaded. I believe the problem is the seal allows coolant to to get around the seal flange and drain from the weep hole.
I'll end up eating this and buying a quality part.

Thanks for the help.
