How to replace alternator decoupler on Dodge Avenger (Fix loud engine noise!)

- This is a fast-paced tutorial for the alternator decoupler pulley 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 alternator decoupler pulley can fix a grinding or whining noise that increases with engine RPM. The decoupler has an internal bearing that fails and results in this weird sound shown at 0:21. 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.
Since you need to remove the serpentine belt and the lower idler pulley to access the lower alternator mounting bolt, this is a good opportunity to replace them both.
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: 15mm socket, electric impact driver, serpentine belt tool with a 16mm socket, 19mm socket or lug wrench, 10mm socket, pocket screwdriver, 1/4 drive flex head ratchet, 3/8 drive flex head ratchet, 16mm socket, 13mm socket, small hammer (not pictured), large flat blade screwdriver, 17mm Hex (Allen) socket.

Nice a fellow Texan doing outstanding work. This video IS the standard when it comes to diy videos. Straight and to the point, no yacking just attacking.
Madvizion here hailing from San Antonio Texas.
Glad to help out!
4 years later and still helping people. Thanks for the video. Followed step by step and took me about 2.5 hours. My advice for anyone having trouble getting to pulley off, use a small screw driver to hold the rotor in place while you hit it with the impact. Worked great for me.
Thanks for still tuning in. Great advice, just be really careful!!
It’s amazing how much noise and vibration can come from these pulleys. My van was making all kinds of grinding noises and you could feel the vibration while driving. I replaced the decoupler pulley on the alternator and it’s like driving a different vehicle. Nice and quiet and no vibration.
Great video! Shared with my mechanic friend to fix this very problem on my 14 avenger. Other than the electrical problems, it's been a great car
Bro that camera angle and easy quick tut is 💯. Do NOT stop making videos!! Make more!
Awesome, i don't know of any other channel working on the avenger
Used to help me with my scooter.. now, ironically, you're helping with my avenger 😂
What are the odds?!
This was a really great before and after. My car sounds like its ready to go 100 mph in 6 seconds when I turn on my car ha ha.
This is an excellent & straight to the point video. Thanks.
Hope it helps you out!
Thanks for the video I was really trying to figure out where that whinny noise was coming from. I have a 2014 Dodge Avenger and this video helped me out alot
This was a big help in replacing the decoupling pulley on my 2009 Avenger. Thanks!
Glad it helped you out!
Thanks for this video my car barley started making this weird noise it not loud but I'm sure this is what it is gonna order everything this week and try do it myself
This looks similar to the POS freewheel-in-one-direction pulley Ford used on the alternator of the 4.6 engine used in the Crown Victoria, (but at least they were easy to get at). Those stupid things sidelined many police cars because they would fail often due to the heavy load placed on the alternator by all the police equipment, the long periods of idling time and the high under-hood temperatures during idle.
Thanks for the Video as tomorrow I'll be replacing the de-coupler pulley, tensioner and idler on a 2.4 Sebring. All failed at the same time so I'll replace the belt as well. Many thanks.
This was my issue thanks!
Thanks, solved my noise problem
Great information
Thank you
Thanks Garret, big help and excellent video.
Thanks!!!
I believe this is the issue with my 2014 avenger. Sounds like one mad leaf blower
Awesome video bro.
These videos r excellent!! But even better is when u talk. U have an excellent knowledge of stuff, and I would rather hear u telling is about your Pinto, or what u like about scooters. That ding ding music is not very educational.
Mine is making this noise and now the alternator is putting out 11v. If I replace this will that fix the alternator?
Can it be done without taking off the wheel
What if your decoupler pulley wont come off? I'm using an impact wrench and a 17mm hex driver and it just keeps spinning
Hit it with the impact in short spurts. Once it starts spinning it's not very effective.
I'm having the same problem. I took your advice and hit in short spurts, but it's not effective. Do you have any other advice?
@@kylerustywilliams you can try some penetrating lube like PB blaster. But you best bet is a harder hitting impact driver. Let the pulley come to a complete stop before you hit it again. Good luck!
@@kylerustywilliams I had to take the whole thing out and replace it all.
@@lyndsayfleming6746 why? What went wrong?
Power steering and alternator is attached together u cant disquinsh which one is making noise they make the same noise in my case it was the alternator
Any way to do it without taking the alternator out?
How does a decoupling pulley work. Cars didn't used to have those
Did it cause any charging problem?
I took mine off and it just spins both ways. How can i remove the pulley?
I think my Dodge aveneger have the same issue
Did your alternator stop charge the battery ?
Wouldnt it just be easier to replace the whole alternator then to waste days gettin that off
i performed the alt replacement on jeep patriot, its removes the same way but getting out of the vehicle is another story lol
Mi avenger sounds like If “is a disel car !
When did Bam Margera become a mechanic?
Proper ppe and then I see the sandles🤣🤣🤣🤣
My car sound just like this, and ppl told me it was my motor.
I thought my P71 was the only car that had one of those.
More stupid stuff on these new cars. I hate that they only run one belt as older cars have separate ones. Ac compressor lock up and still have a belt for alternator and water pump
Sometimes it's hard to believe that the engineers have our best interests in mind...
@@Scooter_911 parts here, get your parts! your out of warranty experts have parts for sale!!!
The good thing about the AC compressors on these Dodge Avengers is they’re clutchless pulleys, so if the compressor or bearing fails, they’ll spin freely and not break the belt.
