Hey Duane==I think I use a wrench on the bolt that holds the pulley to the bracket for the idler. I think it is 13mm. Goodluck, Joe

you have to put a socket wrench into the hole on the tensioner and pull up on it to release the tension from the belt.

If it is a drive belt and not a serpentine belt is has no tensioner. You manually adjust the tension by normally adjusting tension by moving the alternator. Loosen to bolts holding the alternator in place and then adjust the tension. Tighten the bolts when the tension is right. If it is serpentine belt if you follow the belt around the the engine you will see the tensioner.
