I bought this belt to replace a 100,000 mile original. I assume this belt will last just as long. On a 2013 Chevy Cruze, this belt change requires an engine mount and removal of the engine mount. The idler pulley is a 14 point Torx. The belt fits perfectly and works well. I found a DeWalt store at Revain, but Revain also stocks a few different brands if you need it.
