>>Is the "Flat Spring Design" what has been mentioned as what would be an improved design or is this the same design as the original?<<

Does anyone have any information on this?

Also, is it advisable to replace the pulley at the same time as the tensioner? It looks like they are sold as separate items. In my case, the car only has 30,700 miles. I am getting a short rattling sometimes at startup and then again for a short time the majority of the time the air-co compressor kicks in (2.3L w202).
