Review on Dayco 89231 Automatic Belt Tensioner by Jeff Kumar

As a hesitant car owner I wasn't sure if this product would make a difference. However, using it, our team found that the tensioner improved the performance of our car significantly. It increased the longevity of our car belts and provided a smoother ride. The automotive function of this tensioner is impressive, and we noticed an overall improvement in our car's performance. The downside is that it was a bit difficult to install, but the benefits outweighed the challenge. .
