i recently got the a/c tensioner i needed to make my a/c work and i can't figure out how the tensioner goes on, i got it to where it looks like it goes on right but the bolt that adjustes the tension doesnt really do anything i screwed it all the way in and it doesnt tighten the pulley up any.. i look on red pepper racing.com in the service manuals but it didnt really show anything, any help with be greatly appreciated
