I replaced my old waterpump about 6 days ago. Re-using the old one even tho it was fine before i guess distrubed the seal on it and caused it leak bad out of the weep hole. So i got a new GMB water pump from advance auto for $61 installed it, and i've been checking for leaks every other day. I noticed 3 days ago there was some crust on the lip 2 inchs under the weep hole. It was dry crust so i figured it was just coolant that sprayed all over or leaked from the bad o ring on the heater bypass tube. I checked it again today and the crust is back and its semi crust/wet. Its directly under the weep hole again.
According to DMB's PDF a new water pump will leak from the weep hole before the seal "sets" so they claim. I have put maybe 50-60 miles on it so far and i was wondering if i should be worried about this or not. Its not really the work involved in removing it and putting a new one on as thats easy. Its just that if i have too i'll be pissed
