So a subaru dealership was going to charge me almost a thousand dollars to change this part out but everyone says its really easy to do. I need some help an instruction since Im new to this... Here is the thread on Nasioc that seems to be pointing me in the right directions.. http://forums.nasioc.com/forums/showthread.php?t=1206513&highlight=idle+tensioner+pulley The whining is RPM dependent and occasionally causes a weird idle. Could someone snap a photo of this said pulley? And possibly give me instructions on replacing it? I would be glad to pay if someone could help me do it also. hnoes:
