Needless to say, my plans for ordering one from them are out the window. I'm going to hold off ordering one at all until I can verify that it isn't just the pulley that's loose on the water pump shaft. It acts like this is what's going on: the pulley wobbles, but the water pump itself doesn't leak.
Dan, any luck with those pix of those tools you made? I'm planning to work on this over the weekend while the weather is decent.
