Review on 🔧 ACDelco GM Original Equipment 89017309 Drive Belt Tensioner: Efficient Performance and Reliability by Chris Sweeton

This is exactly the same as the factory. The original lasted 18 years. The seal is made in China. The metal case is stamped Made in Canada. Gates did it; This is also engraved on the case. For now, that stopped the whining noise. From what I've read in other reviews, you can also buy the Gates tensor. This is half price and the same.
