Hello,I will be glad to try and assist you with this,Welcome to Just Answer.Hi.The belt tensioner on this vehicle is automatic for controlling tension on the belt.If you are trying to relieve the tension on the belt then on the front side of the tensioner is a 1/2 inch drive square slot to insert a 1/2 inch breaker bar into this slot.You would insert the breaker bar into this and push down on the breaker bar to relieve the tension,then while holding it like this you can remove and replace the belt.Let me know if you need anything else,click accept if you feel satisfied with your answer as this is how I get credited for my time,Thanks Pete!
