My car has had a series of problems with shredding the belt. Yesterday i was driving home from work and it shredded so last night i put a brand new belt on, went to the track and ran a [email protected] was only able to get one run in b/c it was really crowded and they shut the track down half the night but i was still happy with my time. On my way home i picked up a nail in my front tire and it started goin flat so i went to pull over and missed a turn so i stomped it to spin my car around and my belt came off again but without shredding... anyone have any ideas why my car wont keep a belt? Its been in for service 3 times already, ford said they checked pulley alignment and already replaced the s/c pulley twice....
