The idler pulley is the tensioner for the serpentine belt. To loosen it, do the following... - Notice the bolt in the centre of the idler pulley. Find the appropriate socket. - Using your rachet (set to loosen) put the socket on the bolt so that the rachet handle is pointing towards the windsheild. - Push down on the rachet handle. The tensioner will give slack to the belt. (careful because it is under spring tension) - While holding the tensioner down slip the belt off. Gently allow the tensioner to spring back slowly until it stops.
