What usually happens to a contour when the water pump goes out and it overheats. Do the head gaskets go out? I ordered a pump replacement and installed it, but my problem is with the housing. The housing has a small hole in it which is causing the leaking. I have a water guage in my piller and it was up to 250 degrees. It got so hot that my car would not start for about an hour and it was making a wierd clicking noise when I gave my car gas. I started my car today and took it up the street and back and it was riding fine. Any help would be appreciated.
