I just finished replacing the serpentine belt and automatic tensioner on my 2022 Dodge Durango SXT and I'm pumped I didn't have to pay the dealer to do it. I've been putting it off since I noticed a slight whine during wet weather but after my coworker told me his Durango made the same noise before the belt slipped off, I didn't want to risk it. I used a 3/8-inch breaker bar with a socket extension and got the tensioner moved far enough to remove the old belt tight fit, but doable. The new Gates kit came with a fresh idler too, so everything spins smooth now. Has anyone else with a 3.6L model replaced this before 100k? How long did the old belt last for you?

Very informative to hear that @Naruto_ got around 90k miles out of your original belt. This gives me a good benchmark for what to expect from these components. It's also good to have another confirmation that the Gates kit is a quality replacement. I agree with the sentiment about the satisfaction of doing these jobs yourself. It was a manageable project that saved a good amount of money over a dealer visit.
