Today I went to replace a 2001 Ford Focus LX SOHC alternator and serpentine belt. I stopped by carquest and picked up a 6K529 belt, that when searched on eBay brings up a belt that appears to be right for the car as it does not have A/C. The belt and alternator are being replaces as the alternator pulley froze and ate the belt. After changes the alternator and putting the new belt on to match the diagrams that I have found there is still a considerable amount of free play in the belt, enough that it would not work. Any ideas?
