Hi, this thread will probably help you.
Personally I find the tensioner doesn't really go bad. If you think about it, it's just a torsion spring. I found nothing wrong with mine when I had the supercharger out. Still rolling on the original one.
The pulley itself can be replaced separately, but personally I found mine was fine too.
