take your belt and look at it in the sun or a light. Are there any cracks in the ribs of it? really shiny spots? if not, it's fine. As for the tensioners, let the engine run and look at it, if it wobbles just a little bit, its fine. A lot then you should replace it. Tensioners and belts are tricky. If you like to floor it alot, the belt and tensioner will wear out alot quicker than if you drive on the interstate alot and take your time getting up to highway speeds.
