I replaced my water pump last yr. I noticed this year leaking had replaced again

Dont know what to tell you except get it fixed. That's about as much help as we can offer, i think, sorry! Your mechanic can see the leak so let him tell you what the problem is, or get a MECHANIC to pressure test the system and search for leak with a video (bore) scope.

It may be your front cover leaking at the gasket. Mine is doing the same thing and I replaced my water pump also. Its a lot of work involved and I am trying to get a decent estimate. Don't want to do it myself, but dealership is really expensive here....
