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.

Okay I installed my NST pulley on my car had about 12k or so miles on it. I installed everything correctly as well as made sure the belt was not overtightend. I actually marked the position of the altenator before i loosend it with white out and double check the belt tightness after the work was done. At about 18k the water pump failed. Brought it to dealer and they replaced. I know it was leaking cause of the white spots on my driveway and the pink residue on my hood and everywhere else. I clean my engine bay once a month so this is when i really noticed it. It could have been leaking for awile but didnt get bad enough till then.

Then few weeks later about 19k i went to clean my engine bay again i noticed same thing. Not as bad as before but a bit of residue. Also my coolant resivoire is low as well. This time though the belt was overtightend slightly.

I know these toyotas do have issues from the getgo with thier water pumps. Just today a 2003 corolla and 2005 camry came into my shop for a oil change and they both had leaking water pumps. Seems to be maybe one of those "manufactured defects".

I think the fact that i drive agreesively and maybe the NST may have been a contributing factor to the premature failure. But its hard to say. To me it seems like too much of a coincidence. I think even if i didnt have the pulley it would still fail because the fact the parts are problematic from the beginning. I just think that its a possibility it may have accelerated the inevatable.

I am not tryign to stay i believe the reason for my failed water pumps are soley the cause. If you look at the title or my original post there are question marks not a period.
