ok so i just got nates 2.9 pulley in and i cant figure out how to loosen the belt tenshioner to get off the stage 2 pulley can anyone help please its appreciated

 

if you still have the stock tensioner use a 15mm wrench on it (you will see a little square part sticking up behing the idler pulley) put the open end on there and push it back towards the firewall, that's it

 

WATCH your KNUCKLES! lol that wrench likes to slip off the square notch and send your fist into the valve cover. after i did that a few times i got smart and found a slightly smaller wrench and hammered it on the tensioner.

 

tap it down with another wrench or ratchet to get it all the way on, you'll have a hard time getting it off, but it won't slip
