Brought to you by 1AAuto.com, your source for quality replacement parts and the best service on the Internet. Hi, I'm Don from 1A Auto. I hope this how-to video helps you out and the next time you need a part for your vehicle think of 1AAuto.com. Thanks.
In this video, we show you how to the replace a serpentine belt tensioner on this 2006 Jeep Liberty with the 3.7 liter V-6 engine and it's the same part and process on these vehicles with this engine from 2002 to 2012. The items you'll need for this is a new belt tensioner from 1AAuto.com, 13 mm and 15 mm socket and ratchet with a piece of pipe for leverage. Your belt is located right at the front of engine and the tensioner is right here. You just want to put a 15 mm socket and ratchet on that tensioner and pull back on it and that will loosen up the slack on the belt and allow to pull the belt off each of those pulleys. On your tensioner, you want to remove this 13 mm bolt right here and you can see Don uses a piece of pipe for some added leverage here to help break it free. We'll just fast forward as he removes that bolt. Once the bolt comes out, the tensioner will pull right off.
On the left is the old tensioner. On the right is new one from 1A Auto. You can see that they're identical and will mount exactly the same. You want to line up this end in with this bolt right here. Then once you have the tensioner in place, replace that 13 mm bolt. We'll just fast forward as Don tightens that up. Now when you go to put your belt back on, you're going to need this belt routing diagram that shows you exactly how the belt should look. You just want to follow this and make sure that your belt once you get it back on all the pulleys, it looks just like this. Just use this as a reference. It's hard to show it but you can see Don's going to feed the belt into place and put it onto each of those pulleys. Once you have only one pulley left to put the belt onto, get your ratchet and put that 15 mm socket and ratchet on the tensioner, pull it back, put the belt down on the last pulley and then use the tensioner still to make sure that your belt is on each of the pulleys all the way and that there's no chance of them slipping off and that everything is in place. Once you know everything is in place, just carefully remove the socket and ratchet and you are all set.
