Is your Jeep’s engine making weird squeaks or the belt seems loose? This belt tensioner assembly might be just what you need. It’s a direct replacement for part numbers 04627038AA, 4627038AA, 39415, 89689, and 49856, specifically made for the 2012-2017 Jeep Wrangler with the 3.6L V6 engine, AND it also fits the 2018 Wrangler JK model (just a heads up – it does NOT fit the 2018 JL Wrangler). Made from tough steel, this tensioner is built to last and keep your serpentine belt running tight and aligned. It helps reduce vibration, which means less wear on your belts and other engine accessories over time. Installation is pretty simple if you’re handy with basic tools – just swap out the old one. We always recommend double-checking your old part number against our list to make sure it’s the right match before you buy. A good tensioner means smoother engine performance, less noise, and longer life for your belts. Keep your Jeep running quiet and reliable without breaking the bank!
