Review on Dayco 89312 Automatic Tensioner Assembly by Paulo Heisler

- Good fit, unlike the part (made by Dorman Products) that was available from some local auto parts stores and was more than twice the price - What you see in the picture What You will receive: A brand new belt tensioner with a molded plastic pulley. The pulley on this tensioner is slightly smaller in diameter: 70mm (2.75") vs 76mm (3.00") OEM; but when it comes to belt tension, it doesn't make much of a difference. It even helps a little when installing the belt, especially if you decide to install a new belt at the same time as the tensioner; New belts are tighter because they have not been stretched yet. All in all: a good product, well made (to my surprise not made in China but made in the USA as stated on the box) and at a great price! Additional Note: Remember that you will need to reuse the old bolt to install the tensioner as none of the replacement tensioners will have one. Just remember to put some lube or anti-seize on it to make it easier next time!
