How to Maintain the Belt Tensioner on a 3.8L Engine on 2009 Jeep Wrangler?

Start by taking off the accessory drive belt to work on the accessory drive belt tensioner. After that, loosen the accessory drive belt tensioner mounting bolt (1) and take out the accessory drive belt tensioner (2) held by the engine front cover. Because high spring tension holds the automatic tensioner unit together, it is best not to disassemble the part.
