Hello -
I had a setback this week when my water pump started to leak at 175K miles. Complete details here :
Classic water pump coolant leak? - SaturnFans Forums
I don't think this was the fault of the mod. I am pretty sure it started to leak 6 months ago, but the weather was cold enough for me to "muddle along" with a slow leak. Also, I replaced my radiator 13 months ago at 155K miles, so I think this is just normal wear and tear.
However, I wouldn't disagree with the argument that the mod made the pump fail a month or two early (i.e. before high summer).
