Okie dokie! .bad news is I changed the tensioner and the noise is still there...so I've changed all the idler pulleys and tensioner in the front....now I look at the belt and pulleys behind the serpentine belt and their all pretty worn down....and it seems like the noise is coming from one of those idler pulleys....so my question is how hard is it to change those pulleys and belt? It looks like theres a couple screws but is there anything else i need to know? Im pretty confident i can change them
