most Fords have a bolt on the tensioner that when released goes %26quot;boing%26quot; and releases the belt. Find a bolt and undo it.. if that doesn't work tighten it up again and try another.



You dont %26quot;adjust%26quot; the tensioner when the belts back in as such.. The tensioner has a spring in it that does the job for you.



Once the belt is off, look at the tensioner. You'll see that you can wind up the spring then lock it temporarily with the bolt. Then when you fit the new belt, you just release the bolt again and it tensions itself up.



It is a lot harder to explain than to do. Take a photo of the belt before you take it off. Them suckers can be real confusing to thread back the correct way
