I have an 05 Vibe with almost 50k miles. In that time period I have had the waterpump replaced 2 times under warranty (done at two different dealers) and just today "my" mechanic noticed signs of leakage again...white residue around the base of the pump from below. (He noticed only because I asked him to check as he was changing out the winter tires). Never has any of the leaks been major i.e. never any noticeable liquid on the ground but it is frustrating that this car goes through so many pumps. Any ideas?
