IDLER PULLEY

QUESTION: Can you tell me what I need to do to loosen the bolt that holds on an idler pulley on a 95 Buick Lesabre, I haven't really tried anything ANSWER: All you need to do is find a socket that fits it, should be 13mm or 15mm. then using a ratchet turn it counter clockwise. Remove the bolt and idler together. It may be easier to remove the serpentine belt before doing this. This can be done by inserting a 3/8" ratchet in the end of the tensioner and loosing the tensioner to allow the belt to be removed. Draw a picture of the belt routing for reference when installing.
