Review on ACDelco 12609719 Original Equipment Tensioner: Ensuring Optimum Performance by June Reeves

Excellent OEM product. Perfect fit for my 2007 Cadillac Escalade ESV. The only reason I give the product 4 stars instead of 5 is that it only has 2 mounting holes instead of 3 like the original. But according to GM, this is an OEM replacement. This product was made in Canada. I don't really see where the lack of a 3rd mounting hole could cause a problem. You still use 2 holes where you have longer screws. I put the 3rd short screw back in and tightened it just in case I need it in the future.
