Bad productMy belt was making a light noise so I decided to change it. This kit made it worse.Took it to Toyota. Toyota confirmed it was a bad kit.

I had a loud squealing belt that I wanted to replace. As I did some shopping around, and searched some YouTube videos, I realized I should replace all three components. Shopping independently for each was somewhat costly. This package of all three parts together was very reasonable in comparison. It took 30 minutes to do the change out, but no more noise and I'm sure my neighbors are happy. Well worth the expense, great value.

Installed as preventative maintenance. Noisy new idler pulley and chirping belt. Noises were not present until installing this kit. Wasted my time.
