Do you mind if I ask you these questions?
-When did you install the NST pulley?
-When did the 1st water pump failure happen? (1000 miles after??)
-Do you think you know how the water pump failed? (leaking, grinding, etc)

I hope this will help everyone here to understand more about the situation. I have browsed through the pages but didn't find anything about the cause of failure of the water pump.
