2000 vw beetle 1.8 turbo. replaced altenator, tensioner, and serpentine belt. problem is that the new tensioner is not lined up with rest of pullies. It is setting off to one side of the belt not in the middle which is causing it to throw belt off.. Is there some spacers that I missed when I removed the tensioner assembly. It looks like it is 1/4 inch offset on belt. Please help!
