Your belt needs to be much tighter. Jre recommeneds 1/4" gap between tensioner and idler. Have a buddy put a 1/2" ratchet on you tensioner, loosen your 15mm on the idler, use a 36" pry bar and move your idler pulley toward the tensioner by prying against the throttle body. when the idler and tensioner touch then tighten down the 15mm bolt on the idler. start your car and the belt will loosen and give you the 1/4" your after. if its more than 1/4" repeat the process and make it tighter.

note if you use the supplied bolt it will bend and make it tough. pry on the tb gently and it works much better.
