Re: Water pump pulley broken - please help
Good luck, it's difficult to prove that the damage existed before, unless it was pointed out and documented with your original repair. My suggestion is try and find a reputable, independent repair shop and avoid national chains. Sorry to insult anyone out there who may work for them, but they've gotten their reputation for a reason.
I would point out in your defense, though, that it's difficult to break just a pulley without collateral damage, but I'd recommend having all the idlers and pulleys checked as well.
Ever notice that there's so many high performance parts available for GM products?
Did you ever think that maybe they NEED them?
