How do you release the belt tensioner on a 2000 Ford Expedition?

Answer 1

can use a breaker bar with either 3/8" or 1/2" inch drive, whichever fits in square hole. be careful, because that belt tensioner is under a lot of force. You really need 2 people, one to release the belt tension and another to remove/install the belt A further suggestion. I use an 18" long, 1" (id) black iron pipe as an extension for my breaker bar. It makes a world of difference and one person can then de-tension the belt and slip the belt over the alternator pulley.
