Review on Dayco 89391 Belt Tensioner by Marc Alvarez

The price was great compared to the Autozone which was $239 and the other was $334. However, I did notice that the part on the underside of the spring wasn't assembled properly. I had to use a screwdriver and twist it into position. Another thing is that the spring tension was not enough to put the belt on the alternator tensioner. I had to put the belt on slightly and crank the engine without starting it to allow the pulley to fully engage the belt. I expected the Dayco brand to be much better, especially the assembly part.
