Review on Dayco 89148 Belt Tensioner Pulley by Robert Ryokan

Installed on Nissan Altima SL 2.5 2008 MY. This pulley is not as wide as the original part and so the timing belt rides on the very edge of the pulley which is a bit intimidating. The bearing is made in China, I have never heard of such a brand. The original bearing is NSK 6203. Also, the metal used is not as thick as the original Nissan pulley. Hope this disc lasts. If not I just buy a brand new bearing and put it on the original pulley I kept. You should have done that first. You can buy a quality 6203 bearing online for about $5. Hope this is helpful.
