I put a new idler pulley on and I'm trying to get the belt back on and its a pita ! I've use the 15 mm wrench on the notch and it keeps wanting to slip off and I watched a video on YouTube of a Guy using the actually idler pulley bolt to compress the twnsioner but my bolt loosens beforethe shock goes down? ?? And tips or tricks please post them

 

Man up and hold it on the notch lol never had an issur

 

Well me and my dad actually fabricated a nifty little device to hold the tensioner all the way down
