Chrysler, Dodge, and Jeep 2.4 liter world engine "whine" diagnosis

[@nique9520]

This exactly the sound my jeep patriot 2016 is making & no one could figure it out. Thank god I didn't give up on searching

[@skywil4479]

Dude I have been looking for this for two days straight. God bless you

[@CG-ie9oz]

Same. Thx

[@chrismechanic6164]

Actually if the alternator is working (charging) you can change the decoupler pully on the front. That's what is usually creating the noise. It runs about $80 at napa. It's relatively easy to change to. The alternator runs about $300. The decoupler can sometimes sound like a bad water pump also but you'll hear that the noise is on the opposite side of the engine from the w/p.

[@DJNickeyB]

Thank you for this! I recently starting having this noise and I knew it was the pulleys specifically the alternator

[@Fae_Zen]

Perfect that's the sound I been getting and now know what's going on

[@vincescalise4821]

Very informative video thank you

[@wildixon4918]

Thanks a lot! This is the noise from my Patriots wife, thanks a lot again.

[@FallWarrior-si5eu]

I have that sound, but it becuase i have a supercharger on mine, i got a custon made Whipple Supercharger for my 2.4 L multiair Jeep

[@BlackHawk0717]

Hey i have a 2012 chrysler 200 lx with a whine noise too. I checked what you showed me and everything looks good.

[@MotorCityMechanic]

First thing we need to do is see if it is belt driven. If you can get the noise to happen all the time when the engine is idling.....then remove the drive belt and see if it goes away. If so then its belt driven. The most likely issues will the alternator, either idler pulley or belt tensioner pulley. If the noise is still there with the help removed then it might be a trans related noise such as trans pump. Thanks for the question and make sure to subscribe

[@drenanby8773]

I wish you would have been out side of car

[@juanteniente7928]

I have similar noise when i was in line at drive thru and when i went to accelerate my avanger wouldnt go. I had to put in park turn off then start again. Did it twice while in line. Would that be the reason as well or totally different?

[@gregorytolson4621]

Does this sound have a tendancy to be loud on cold start up and go away after warming up?

[@brooklynnewyork718]

Looking for videos on changing motor mounts on 2011 jeep patriot sport.

I dont have any at this time but I will certainly keep it in mind as a future video. Thanks for the request and make sure to subscribe.

[@12vLife]

Sir John, we have the same engine... how many miles on your 2.4 when you first noticed it? Are able to reproduce while parked? When driving off? does turning the A/C or heater off help? High octane gas help? Were able to resolve it? Was it caused by low oil level damage?

[@mistersniffer6838]

Thanks!

[@cherish22]

How do you change the idlers ? I have this exact problem 2013 Chrysler 200 2.4l lx . But the alternator is fine it’s just the idlers

[@tharealjondoe8811]

What about the oil pump when you first crank it up?

[@robbigemon1868]

Cant the alternator pully just be replaced or whole alternator

[@brigzy37]

I have an 07 jeep compass 2.4 4x4 and it just started making a squealing noise when i accelerate what u think it can be

hi i have sebring 2008 convertible 2.4L dual vvt its timing chain or belt please reply and thanks

It will be chain. Thanks for the question and make sure to subscribe,

great video I have a 2012 Dodge Avenger with that same sound so I'm a go outside right now and check what you just showed me on the video and check because I saw a position to and told me that it might be the serpentine belt but I got it but just in case I'm going to change the belt to Output I need a video on how to ride it and how to change it please thank you

[@MotorCityMechanic]

Your welcome. I sent you a message on your other reply about the belt. Make sure to read that message as well.

[@cmdaniels55]

Hey buddy, u helped me out one year ago with this exact problem. I replaced alternator and issue solved. Yesterday i cranked up the car and the whine was back after one year and 10000 miles on a remanufactered alternator. Do you think that bearing could go out so soon and that this is the same problem. Big fan. Thanks

[@MotorCityMechanic]

Reman aftermarket alternators are always questionable. They are one reason why I try to not use them when ever possible. Try to narrow the source of the noise and if needed....remove the belt and turn the pulleys by hand to see if you can tell which might be at fault. Thanks for returning and for the question.

[@sandalwoodcg2007]

Hey David,, is it possible to change just the clutch bearings instead is the whole ac comp?? It’s the same 2.4 liter in my ladies Sebring..My ac still blows cold but it’s getting a little noisy.. thanks!!!

[@DougsHomestead]

I think I have this engine in my Dodge Journey.

[@bearwhatuwear]

crank shaft on 2013 journey wont loosen ,change engine,or blow up car,changed transmission last year and two throttle controls so far,going broke chryslar.

[@andreswar7271]

Gracias Motorcity. Tengo una Jeep Patriot 2007 con un ruido como de turbina, es el mismo que describes en el video. Como ves I do not speak English, asi que si puedes recomendarme una sitio web donde pueda ver este problema mas en detalle y en español te lo agradezco mucho. Thanks.

[@MotorCityMechanic]

Las ocasiones son que usted tiene un problema del cojinete del alternador o una de las otras poleas. No sé de cualquier otro sitio web que están en español tha podría ayudar.

MotorCity Mechanic 08 Jeep Patriot 170000+ mi 5MT SPORT I have a question... I think I heard my car making this sound almost a week ago.. it continued and wouldn't let up. Until I was leaving work and then without warning at the traffic light, my car stopped running. I looked in the dash and the last code I saw was FUSE warning. Now thinking it was the battery, we tried to jump the jeep but the cable was getting very hot and we checked to see if it was the terminals, but the terminals were correct. With the connection it wouldn't even come on let alone turn over. Is it possible that the whole car will not get any power if the alternator is fried?

[@MotorCityMechanic]

Daddio Green The alternator may be shorted out internally and draining the battery and causing other issues. I recommend taking the alternator off and see if any issues why turning the pulley. Also look for that rust colored dust on the front. I feel it's most likely going to be your issues.

[@koknock61]

Thank you. Jeep Patriot just started to wine and I found it. Can you recommend and power upgrades?

[@MotorCityMechanic]

Welcome. The only recommendations I have are to go with the Mopar replacement parts when avail. I dont have any faith in aftermarket parts.....they just dont seem to last. Thanks for watching and make sure to subscribe.

[@billgateskilledmyuncle23]

How many miles when this started? I've owned a Patriot for a year now and have 54k miles, just wondering when I can expect this, too.

[@phillippardo5712]

Hey thanks for the video, I'm currios I have a 2010 Jeep compass is Normal for the engine to sound kinda of like a diesel? Like a continuous ticking sound? I thought it was normal but I heard someone's 08 compass and it didn't have the ticking noise?

[@MotorCityMechanic]

It depends on how loud Its something I would have to hear in person to be sure to see if its abnormal and if so....to also figure where its coming from.

[@phillippardo5712]

It definitely seems to be coming from the fuel rail on top, I listened with a screwdriver on top if the valve cover and didn't hear it, but when I put it to the fuel rail. Bingo definitely seems like it's there. I was thinking injectors..? I could if sworn I've heard newer 4 cyl. Engines sound similar. Really wondering if it's normal..? Btw thank you for replying!

[@markess5213]

World class engine?

[@ernestperryjr]

How long does it take for one of these engines to start developing this problem? I've got a '12 Chrysler 200 with this engine in it - right now, it sounds fine but that's only because it has around 18k miles on it (got it low-mileage, and since I'm a homebody it has stayed low haha) Thanks!

[@MotorCityMechanic]

+Ernest Perry Hey Ernest....it depends. It may never have this noise or issues. Just depends on the bearings. I wouldn't say that everyone will eventually need to have the pulleys or alternator replaced but I would think it could possibly happen over time. I actually haven't done one myself ever since the video was made. I use to see then from time to time.....but not lately. That doesn't mean that the independent shops aren't seeing them. Once most vehicle start getting miles on them.....they start going from the dealership to the independent repair shops so that can explain why I don't see them much any more.

[@jeremy8715]

What about the Jeep tj? I have cold engine knocking.

[@MotorCityMechanic]

Hard to say with the year. Nothing really common that could cause that so it could be internal and require tear down if needed.

[@sayuncleordie]

Just replaced the alternator. Then that noise showed up.

MotorCity Mechanic my car just started making this sound its a 2012 chrysler 200 also i only noticed it after having belt changed. could that have anything to do with it? thanks

[@MotorCityMechanic]

It could be a cause of the noise. I recommend doing the visual inspection that I showed to see if a pulley or alternator is needed. Thanks for the question and make sure to subscribe

[@beezertwelvewashingbeard8703]

This is not an engine internals situation. This is external accessories wearing out and are easily and affordably replaced. 10 years in and these 2.4 engines are proving themselves to be reliable engines, even in larger cars like the Dodge Journey.

[@MotorCityMechanic]

Your absolutely correct. Some common issues for sure but the engine itself has held up great.
