I ordered a belt for an 04 Ford Focus SVT and received part #F8RZ-8620-AA. I've been having issues finding a correct belt for my car and went with Motorcraft cause I thought for sure it would be correct. This belt is way too long, the tensioner won't even put any tension on it at all. It has got to be the wrong part number, as all of my pulleys are stock. Any help you can offer, I'd sure appreciate it.
