the spring is used on a 95 to tension the pullie then the bolt holds it in place. The spring is only used to tension and is not left installed. I figure the factor had a setup to tension the belt, that used the pin and the spring. The tensioner is bolted down and is suppose to hold the tension of the belt. When the belt streches it hits the cover. I replaced my timing belt at 104K and at 121K it is not making any noise
