After 4 dissapointing performing miles; the serpebtine belt blew. This was when I was halfway finished with pulling out serp belt pieces. The steel belts kept it all from turning to dust. It is evidence of incompetence. From this point forward; I am not happy. I have had no transportation for a month. I am patient but come December 6th it will be towed to a shop that has done "hundreds of e-force installations".
