Changed the belt and tensioner assembly on my wife's Tribute. I used a Dayco tensioner and Dayco Poly W belt. The original assembly didn't squeak BUT had some play in it that the Dayco video indicated the need to replace. Very easy install. Question is, how good is the Dayco tensioner assembly? The Gates assembly @ O'Reillys didn't look as quality as the Dayco and with the Advance discount codes, it was much cheaper.
