HelloCustomer could you tell what engine you have .....4 or 6 cylinder.
This will help me answer your question
OK, There is a belt tensioner on the engine that has a large spring inside to keep the belt tight. To remove the belt you put a 3/8 drive ratchet in the square hole in the belt tensioner and pull the tensioner to loosen the tension on the belt. Here is a picture that might help you.
