That sucks, I am still trying to figure out how to replace the stock S/C bolt that I broke when installing my C3 pulley. I would like to be able to take it to the dealer and say, here fix my cooling problem. I would rather not chance voiding my extended warranty, because of a bolt. Good luck. I am looking into the belt wrap now that I have powder buildup on the S/C pulley, which I am assuming is slippage. I found a billet 90mm idler pulley on ebay, but thought it was a bit big. I suppose I will just buy the stock one and use it for now.
