- It's a Jeep World - Replacing the Idler Pulley, Tensioner Pulley and Serpentine Belt on a 2007-2011 Jeep JK or JKU
Recently - 7/23/2020 - It was brought to my attention (by Brankz) that in the video the belt may have been routed around the components incorrectly. I want to state for the record, the routing in this video is one way to route your belt on a 2007-2011 with AC. The belt on this Jeep has always been routed in this way, there are diagrams out there that show the belt in a different configuration both ways work, remember because it is different doesn't make it wrong. If it works, it is not wrong, it is just a different method.

Great video, I was able to change the belt both pulleys and the alternator in less than 30 minutes!!!! I am proud of myself. Thanks!!!!
Outstanding!!! Good Job 👏🏼
Great video, I had to replace my idler pulley after it left me stranded in the middle of nowhere. Luckily I was able to get a ride to Autozone and back to my Jeep. Turns out that the rubber part inside of it was all worn out and it wobbled enough to let my serpentine belt slip out of place. Now I keep a pulley and belt in my toolbox at all times.
Glad you got it changed and the video helped our JKU years are easy to work on
@@ItsaJeepWorld They really are easy.
Thanks for this video! I'm embarrassed to say but my JK has been squealing for almost a year and I always assumed it was my alternator pulley. My alternator craped out on me so I changed it over the weekend & was distraught afterwards because the JK was still making the noise after I installed it. After watching your video, I changed the idler pulley in a few mins and that fixed my issue! Thanks man!
Awesome!! Good job
before doing anything to my jeep I always watch a youtube video just to make sure I know what im doing and what I need, great video! mine both had decent amount of play and sound like a dying chicken when its cold out lol
Thought top belt suppose to go under the idler pulley then to alternator??? Seems like water pump pulley has less grab with belt going over idler pulley.
It can/does.
Underrated video , great explanation , I weeded through 20 to find this. Question though is there a way to loosen or tighten the belt not fully releasing or it it just a set tension
It’s set tension via an internal spring in the tensioner mechanism
Thank you for this video I did the idler with not a single issue thaks to you. 100% Props... 2010 JK 2dr
Awesome!!!!!
This is exactly what I was looking for. Thanks!
Jake Kos Awesome, hit like and pass the channel to your friends I have some new stuff coming up soon

Great video. Thanks for sharing. Saving me money bigly today!
You just saved me $315. I will be doing it this weekend and yes I just subscribed to your channel.
None804 Glad I could help, thanks for Subscribing
I believe it is the same pulley/same price (idler and tensioner) on JK.
BVan I believe they may be the same pulley if you just need to replace the pulley and not the whole tensioner
@@ItsaJeepWorld Yes I just finished it, I got the idler pulley at at Autozone 17.99 and there is a note that says "tensioner pulley" when you look for idler pulley on their site. Duralast Idler Pulley 231144 it says. The pully is working in the tensioner ass. and there is no longer the "chirp" that was driving me crazy! Thanks for video.
BVan I’m glad it worked out for you and the video was able to help. Pass the channel on and don’t forget to subscribe 🤘🏼😎🤘🏼
Great video. Very well done! Thank you.
Much appreciated
Good demonstration. Thanks for posting.
Thank you! I hope you subscribed, I’m glad it helped you
Only problem is you put the new belt on the wrong way.
You and 20 others said the same thing. If it works ‘Run it’
I think I eventually changed it only due to peer pressure 🤣🤣🤣
@@ItsaJeepWorld yeah it probably doesn’t affect it all that much. Your pulleys are all still turning. But if you look up the belt diagram, the belt goes under the idler. Jeeps man, they’re money pits am I right? 😂
@@RedRockCrawlers too true
I can't find just the tensioner pulley when I search. I can only find the entire assembly. Is the tensioner pulley the exact same as the idler pulley?
Yes, it may be a different number but the same pulley will work, another subscriber just said the same thing
Interesting, that’s not how my 07 Rubi serpentine belt is routed. You have it going from the water pump to the idler. But mine goes from the the water pump to the AC comp.
Same. On my 08. Which appears to make way more sense.
Great video! very easy to follow. Thanks!
Jeremy Loya I’m glad you liked it. I hope you subscribed and checked out other videos I have to
Can you give more tension to the belt?
No, it’s an auto tensioner non-adjustable
@@ItsaJeepWorld ok thanks again 👍
Is this the 3.6 engine
No, 3.8
Great video!
Thank you very much
Great video.
paul joey Thank you
Is the belt on right?
Yes
Belt goes under idler pulley on my 2010 Sahara. Research it
Agree to disagree
I’ll caveat my first comment with, ‘if it works it’s not wrong’ I’ve run it like that for four (4) years and no issues. Your belt under the idler pulley is a manufacturers suggested routing of the belt. 😎
friend the serpentine path is wrong, see the manual.
alex hlanda it’s right for my Jeep 07-11
Hello !! My jeep is 2007 and in the manual the serpentine route is different, see other videos, send me your email to send photos of the manual.
alex hlanda I went by the diagram on my fan shroud
ok ok I think the two modes are fine, thanks I used your video to change my serpentine, greetings from Mexico City
It’s a Jeep World I hAve an 07 manual as well and it is different then what u did but it might just be that way for both
“As you were” sounds like some Marine Corps slang
Yup, Retired Marine EOD MSgt
@@ItsaJeepWorld Rahh
Belt is install incorrectly needs to go under not on top
Not on a 2007-2011 with AC
It’s a Jeep World i have the same engine dude in the idle pulley you have it in top needs to go under
BRANKZ ok, I’ll look in the morning. But it’s been on there since I made the video, I could have changed it and just forgot to make an edit. I’ll check. I’ll let you know. Thanks for the heads up
It’s a Jeep World yeah man not trying to be a fuck or nothing but putting it on top will make the pump run with less RPMs making the pump pump less fluid wheel will feel a bit more heavy and you make the box and make make extra work
BRANKZ i just checked the video, my Jeep (which I just finished a 3 day WindRock Trip) and a diagram from my website. You are correct that the diagram shows what you are talking about. I find it interesting that my belt has ‘always’ been routed the way I have it with no issues. I’ll make a note in the description to acknowledge the two different ways to route the belt. Thanks again for pointing this out, we are always learning.
The dealer wants 208 for the tensioner..the whole thing they only sell
