I'm replacing the serpentine belt on a '04 Pacifica and I'm stuck trying to get the old one off. How do I release the tension? I see the tensioner but I'm not sure how to rotate it. Is there a special tool?

Thanks,
Tim

 

I figured this out and post it here for reference. There is a square hole on the tensioner. A 3/8" drive fits in it and allows the tensioner to be rotated. The space is very narrow, but there is a special tool called, oddly, a Serpentine Belt tool. It is available free for rent at many car parts stores.
