I ran across an Import Car parts store in search of an idler tensioner replacement which I broke by overtightening it. The store has one in their computer called a Belt Tensioner Assembly and they guy said it probably includes everything already attached to the mounting plate and it cost $51.00. The computer also listed it as the ACC and ALT belt tensioner which is the one that I broke. So does anyone know if this is what I need or not? Thanks

 

Yes it sounds like the right one (the PS belt doesn't have a tensioner) and the price is about right. The dealer should have an exploded view on microfiche to see what parts are included.
