Review on ACDelco 12609719 Original Equipment Tensioner: Ensuring Optimum Performance by Bill Pulse

I bought this to replace my 2008 GMC Yukon Denali and it fits perfectly - I used to have a 3 bolt model and this one has a 2 bolt model but it doesn't matter performance wise. It holds tension like the previous model, I just screwed the remaining bolt back into the same spot on the motor. So far no noise after 1500 miles of use, good tension, no slippage. Excellent quality as expected from ACDelco.
