How to replace serpentine belt, tensioner and idler pulley on Dodge Avenger (Fix engine noise!)

- This is a fast-paced tutorial for replacing idler pulley, serpentine belt tensioner, and serpentine belt on a 2008, 2009, 2010, 2011, 2012, 2013, and 2014 Dodge Avenger. But because they share the same platform this video would also be relevant to the Chrysler 200, Chrysler Sebring and Dodge Journey equipped with a 2.4 liter 4 cylinder engine.
Replacing the idler pulley and tensioner can fix a grinding or whining noise that increases with engine RPM. Replacing the serpentine belt or even the tensioner can solve a squealing or chirping noise that occurs on startup, when the AC is engaged or even when a power steering load is placed on the pump.
The Dodge Avenger has a notorious issue with the alternator decoupler pulley. When this decoupler fails it can make a similar grinding, whining or moaning sound. Make sure you check the decoupler pulley if your vehicle is making a strange engine noise before installing new pulleys and tensioner.
You'll notice at 2:37 I remove the bolts that hold the tensioner in place in a peculiar manner. This is the easiest way I have found to remove the tensioner. The pulley of the tensioner blocks your access to the upper 13mm bolt. You'll need to put tension on the tensioner to move the pulley out of the way, but this can get tiring and is sort of awkward. I've found that if you loosen the top bolt a little, then remove the bottom bolt you can move the whole tensioner into a position where it is easy to access the upper bolt.
You might also notice that the bolt head size is 16mm on the idler and tensioner on the original equipment but the aftermarket parts use a 15mm bolt head. This is normal and will not affect the performance of the part.
Here are some links to the parts I install in this video:

I always perform repairs according the factory service manual. You need to have all the information (toque specs, testing procedures and schematics) to insure you've pinpointed the actual problem and to insure your vehicle is safe after you've completed your repairs. You download high quality factory service manuals here: shrsl.com/1llp5...
Here is a list of tools I use in this video in order of which they appear: serpentine belt tool with a 16mm socket, 19mm socket or lug wrench, electric impact driver, 10mm socket, pocket screwdriver, 1/4 drive flex head ratchet, 3/8 drive flex head ratchet, 16mm socket, 16mm wrench, 13mm deep socket, 13mm shallow socket, 3/8 drive universal joint, 15mm wrench, 15mm socket, 15mm socket for serpentine belt tool.
Here is a serpentine belt tool similar to the one I use in this video amzn.to/2SFaya0

Wow you are by far the best in showing your videos. The rest I've seen can't come close to how you do things the right way. Thank you for us 2 % who is not mechanical inclined. Your are awesome brother,
This is easily the best video on TH-cam on how to perform a car repair. From the camera angles to the belt routing to the tool list. Thanks for putting in a conscious effort to leave no stone unturned. 🙏🏾🙏🏾
Thanks for appreciating the effort my friend!

Good video. I replaced both of the pulleys you did in this video plus the alternator and put on a new serpentine belt. For whatever reason the upper idler pulley didn’t seem bad at all and now my car is silent. Can barely tell it’s running when sitting inside lol.
Wow! I'm super impressed, that was the best mechanic video I've seen yet. So detailed, I like how you mentioned all the tools you used. You just saved me bro, thank you and God bless
Glad it was helpful! Good luck! You can do it!
@Scooter 911 Thank you hun, I work on cars as a hobby and this was my first time doing the pully and serpentine belt. Your video gave me confidence.
Finna be my first time too 👑🙏🏿
Garrett this is a great video. Thanks for posting. Wish you'd do more Avenger repair videos. Dodge should've made that car until 2018 or 2019....
I started my car and it hat that same noise. Helped identify the problem. Thanks for the video
Excellent!
Hey man just fixed my car because of your video. Thanks a ton
Awesome! That's exactly why I make these videos
Thanks for the help. I made a few variations thought, partly due to my tool selection. I removed both idler pulleys and then moved the alternator out of the way which made changing the tensioner easier. And I had bought the pulleys, belt and tensioner as a kit so all getting done anyway.
Very informative, and well shot DIY video. Thank you 👍
Beautiful video. Very nicely done. Great that you included all the smallest details. After all the unknown is what we the unknowing are looking for. Thank-you.
Thanks!! I Put the belt on with the black pin in the tensioner then let it go... the belt was way to tight!! Took the belt off let the tensioner go put the belt on... now it runs fine..
Good job on the video...Mine is making the same noise...And yes I did replace all that too, but still making noise, now the belt won stay on...WTF?...........I even replace the p/s pump...Still mKING THAT BAD NOISE.....Am tired of throwing parts at it...Any one have an idea whats going on..?................John............
Just an FYI some may know this already. New belt kept coming off pulleys get one on, another fall off. I finally used plastic wire ties tied to different pulleys and that did the trick. I was able to use my 3/8 breaker bar with short piece of 1/2” conduit to loosen tension pulley
Helpful video, thanks. The pin came bent and stuck in my tensioner making it impossible to install with the pin still inserted. Seems to be common. I chalk it up to shoddy aftermarket parts. Second, I highly recommend having extra long 15 & 16mm wrenches to crank on the tensioner bolt. Very difficult to get leverage with a standard sized ones due to the location.
READ THIS IF U CAN'T GET THE PIN OUT! great video, spot on. Except it took me over a hour to get that pin out. I finally had to take the pulley back off and saw the pin in half then both halves fell out no problem. But then it was a bitch to get the top bolt tightened. Needed 2nd person there to hold pulley back as far as it would go. Live and learn.
I'm experiencing this right now. It's insane to make this design but unable to get the pin out.
Thanks for the video as tomorrow I'll be changing the same plus the de-coupler pulley. I suppose it's for the better they all failed together.
Sometimes it just works out that way haha
Great video and explanation Sir, thank you!
Thanks! Hope it helps you out!
My belt keep tearing up and coming off and my power steering locked up it’s the 3rd time this belt came off what am I doing wrong?
Same. Did you figure it out?
Thank you so much for this video. I started working on my car in 2019 and a single mother. I discovered this problem while putting my alternator on my car and almost burst out in tears cause I thought the pulley was connected to the engine. My question is does it come as one unit?
Very helpful, great video!
My car doesnt really make bad noise but the belt keeps wanting to slide off. Whats the issue im having?
Can you remove the pin of the tensioner after installing the belt?
Yup!
Thanks for this video.
Great video!. Ill be doing this on my 2010 dodge journey, it has the same 2.4 as yours. I couldn't find any video on it but yours will do just fine. Thanks again.
So I just replaced the belt but after a 1 min or 2 it starts derailing to the right? Any tips?
Lol
Mine too. Did you figure it out?
Play at half speed for a real treat. CHEERS!
Good job on this one . Thanks!
Dope video!
Awesome video!! I am about to replace my tensioner and 2 other other pulleys on my 13 Avenger, do I need the special tool to temove or put the belt back on?
You can use a standard ratchet or a wrench but the serpentine belt tool sure makes it a lot easier!
Is that a ratcheting S belt tool?
Heck yes it is! Now that I have it I don't think I could live without it!
Thanks for the video. Is it necessary to replace the tensioner and the idle pulley if I just want to replace my squicking serpentine belt??? Thks.
Glad you liked it! No you do not have to replace the tensioner and idler if you just want to replace a worn-out squeely serpentine belt! Good luck
Great video
How much does that type of repair cost?
My 2010 avenger rt serpentine belt broke today... My steering wheel was stiff as hell while driving..what would be the average cost to replace?
Dang I was hoping to hear the afterwards if that noise actually went away
Is it possible to replace the idle pulley only without complete tensioner
How much would that one part will cost that was attached to the pulley?

What part is the one that's on top of the alternator?
You wear the same safety boots as me
Can you link to the serpentine belt tool you used?
awesome video , one question tho , why not just replace the tensioner pulley only , cause tensioner itself is a bitch to get to , and its the pulley thats bad , right ?
Where did you get the wrench you used for the tensioner pulley? I could use one of those
I got mine off the matco truck a long time ago, but i just dropped a link in the description to a similar one that i've seen a lot of technicians use. Its equally slick.
Love the music!
I know right!?
My 2013 avenger makes squealing sound when AC is on and I’m in D and I gas to move but stops after a few seconds but always does this. Will doing this fix this as well?
More than likely!
Garret Seesing thank you.
The best
thank you very much!
Any other tip? Im going to do this job on my av 08
Just take your time and get ready to say some swear words. I have found that it's easier to work on the alternator without taking it all the way out of the car. I just get it loose and position it so I can get my hex inside the pulley. Good luck!
@@Scooter_911 Guess what! I only replaced the belt and the squeak went away, removing the tire gives so much access to the pulleys, thanks a lot.
Question sir: a mechanic installed pulleys and serpentine belt in my 2013 2.4 avenger. Then after a week it fell off while driving. So he installed a new belt but installed a tensioner this time. It was good the whole winter. Although still makes a squeaky sound. It just fell off again today when the weather got cold. And in between the last time he installed the belt i had to get the power steering return and pressure hose fixed twice. Does it have anything to do with it? It cost me too much money. Please help
This avengers are trash. Chrysler shouldnt sell this shitty vehicles! Im so frustrated.
How long did this take?
Anyone else surprised he didn't run it after so you can hear the difference?
The reason he didn't show the sound after is because that wasn't the issue. That sound is the alternator pulley.
🙏🏿🙏🏿🙏🏿
What's the total time to do total job
at the last dealership i was at we charged an hour for uncrate/PDI usually it wasnt hard to do it in under an hour. but then again we were doing them all the time.
Hi thank for your video, it was really helpful, I tried to remove the belt tensioner with a regular 13 mm socket and it’s so difficult, finally I could change it but the sound is still there, so I don’t know what it could be, it only sound when I put the car in drive, reverse or when I turn the lights on
You need to change your alternator
Dope Az beatz
Should you/can you put belt on before pulling pin?
That's what I was thinking. I just changed everything on my 2.4 journey and couldn't get the new belt on. So I put the old belt back. It would have been a piece of cake if I left the pin and pulled it out after getting the new belt in position.
Decoupler pulley looked trashed
Video would have been alot better without that awful music
