I just got some great news on this repair last night. My sister took her car in to get an oil change and have the water pump looked at (she was told before I did all the work that it might be bad, but it is still under a waranty from recent replacement). They did a preassure test of the cooling system and they found no leaks!!! This means that 20+ hours of work I did outside in the 30^-40^weather for free paid off. I'm just a little excited that I did it right, espeaially since I've never done it before!!!
