2012-2017 Jeep Wrangler JK 3.6 alternator replacement 

Thank YOU! I’m currently changing my alternator on my 2020 jeep gladiator. Normally I would just call my dad with questions. He passed not too long ago so I’ve turned to RU-vid. Because I’m stubborn and like working on my jeep on my own. I have watched OVER A DOZEN videos! YOURS is hands down the best one. So thank you for being a stand in dad for me on this project. My next project is transfer case seal haha 😅

Total success! Minor hiccup on breaking clip while removing intake unit. Saved myself $20 by using 1/2” ratchet rather than breaker bar. The breaker bar task was a doozy but with someone else’s help, was able to move belt on and off. I know this video saved me hundreds of dollars. Just wanted to say thanks! Truly appreciated! 10 out of 10 stars!

By far the most useful, clear, and thorough instructional how-to’s when working on Jeeps! Please keep them coming!

High praise to you for this highly instructive video. This is the ideal level of detailed verbal instructions and actual physical demonstration. This is the gold standard for instructional videos!

That was the best car repair video that I've ever seen. The narrator was so clear. Every detail was covered. The pace was fast. The camera has perfect visibility.

Thanks for the great video. Still helping people out 7 years later.

I have a 2018 Jeep Unlimited Rubicon and was viewing this video to be more informed about my Jeep. I want to extend my compliments to the mechanic and videographer. The mechanic was clear, precise and explained every detail while the cameraman did his job. Nice work guys. You also saved me some money in the future if I ever need an alternator or a new serpentine belt. Well done and keep the videos coming.

On 10 year old Jeep that breaker bar part is not a joke! Took some elbow grease 😂 this video saved my life! Amazing tutorial 👍🏻 this man is saving lives!

Awesome! You should be doing all how -to videos!,, thank you for the concise, no BS, straightforward video with the perfect amount of Detail! Great job.

This is by far the best video I've seen on the subject, thank you sir.

Awesome video. I actually only watched it to see how to replace the belt, figuring it would be covered. So this video is not only a great video for alternator replacement, it's incidentally also the best video on youtube for how to replace the serpentine belt as well. Thank you!

Awesome video! My alternator went out a few days ago, and my husband ordered a new one for me. It arrived today while hubs was at work, and by following your video i was able to remove and replace it in just over an hour on my own! Thanks to you my husband has his whole evening to relax after work, and i have a lot more confidence when it comes to doing little jobs on my jeep! Thank you!

Hey David, I’m absolutely 💯 confident that I can do this job because of your very detailed Ana’s clear video. I just subscribed and will be checking out your other videos! Thanks brother. Keep doing what you’re doing! Stay blessed!🤙🏽

Thank you for this clear and simple how-to. I am not skilled in auto-mechanics, but, with this video, I feel confident I won't screw up my Jeep.

Best online mech video ever. Direct... to the point and simply put. Angles were great. He even said the right size sockets needed. I have never changed mine before. Did a full replacement in 45min.

Very informative video! I feel like a fool for just having paid $300 labor for this exact job.

David, you are the man! Seriously this video is done at the best pace & every shot is extremely clear. I definitely feel more confident & will be replacing mine tomorrow. If I could, I’d definitely buy you a beer! Cheers brother, and thank you

I replaced my alternator yesterday after watching this video. It was pretty easy. The hardest part was releasing the belt tensioner since I was working alone. I stood in the front of the Jeep on the passenger side and put a cheater on my breaker bar then leaned my weight into it. The hydraulic cylinder compressed after a moment and I was able to slip the belt off the power steering pulley. Putting the belt back on was easier than taking it off. I did not remove the triangle bracket and instead just removed the alternator. I could not get the small electrical connector on the intake to unplug and I was worried it would break so instead I just rolled the whole air intake over on top of the engine and left it plugged in. There is enough slack in the wire to do this. The two long bolts on the alternator have a ridiculous amount of thread on them, a lot more than I anticipated but it was fine. The Jeep dealer wanted $1,190 for a new alternator which includes labor. They also offered a remanufactured alternator for $512 installed. I bought a remanufactured alternator at O’Reilly’s for $224 and installed it myself in less than an hour. The alternator from O’Reilly came with a lifetime warranty where as either option from the dealer did not. I am an old man with serious health issues and I got this done by myself. If I can do it, anybody can do it.

We’ll done with the instructions. Camera angles can play a big part of good instructions video. We’ll play. 5 years later you still saving people money. I appreciate you.

I just followed your instructions to the letter and the alternator replacement was so simple. The hydraulic tensioner was the worst part. Took about 1.5 hours all in

This video should be the standard of videos for mechanic work. Clear, well described steps with great camera work and lighting. Thank you!

I just watched to see how to change serpentine belt on my wife's 2014 Wrangler unlimited Sahara! Fantastic video killed two birds with one stone. 63 years old always learning new things! You are a great instructor ! I just subscribed you have a fan!!!

Thanks for the info! Yours is the only video that I saw that showed how to release the two stage electrical connection on the back of the alternator.

Would you happen to know the torque specs on the 2 bolts that mount the alternator bracket to the timing cover and then the 2 upper longer bolts that mount the alternator to the timing cover as well?

One of the best installation videos that I’ve seen.

Thanks for the very informative video, for what little info is needed. By that I simply mean because it's a pretty elementary repair, not because of the amount of info. In fact, for what it is, you managed to detail every step in the most professional and clearest way possible. Im thanking you for the video because Im doing this job tomorrow for one of our customers, off the clock for cash. We dont actually work on customer's cars, we work on their motorhomes. I'm an RV service technician. But we try to do little things outside our wheel house for good customers. Now that Ive seen the job done by someone who is obviously a professional, I can go do it tomorrow and look just as professional. In fact, before the customer gets there, I can have every tool needed organized and laid out on the cart in order, 8mm, 10mm, 13mm, 15mm, 16mm, ratchet, impact driver, breaker bar, small flat blade screw driver, gloves, throws and fender covers, all ready to go so I can get in and get out and look like I really know my shit and impress the customer!! So, again, thank you! 😁🤘

Excellent video!!! One of the best I’ve seen on how to work on my wife’s Jeep. Loved how you described everything and great camera work. Thank you 👍🏼👊🏼

Excellent! What a great explanation and demo! I tried to do this the other day, but couldn't. Teaching me about the hydraulic dampener and the correct direction to rotate the pulley will make all the difference. Thank You! Great logo, by the way.

Just took mine off easy enough...the mount bracket didn't need to come off thanks a ton

Nice video. Heads up I did not have to take the bracket off. Just the top two bolts to the alternator

Great Video David ! After watching it I had no problem at all doing this job myself after watching the Video! Thanks !!

I’m not a mechanic. Great Video! By far the best I have seen! Easy to understand, step by step for a novice. I feel like it could do the alternator myself with the right tools.

You helped me put my rockers and lifters in and now alternator! Thanks man!

GREAT VIDEO, STRAIGHT FOWARD, ATTENTION TO DETAIL, DESCRIBED TASK UNDERSTANDABLE, WELL MADE.

Absolutely the best! David you have a great teaching gift. Very clear, thorough and easy to understand. Thank you for such high quality videos.

Hands down the best video, and a great lead in for changing the serpentine belt and also being able to create room to do the water pump for the 3.6 L Jeep Wrangler. Thank you very much for your time.

Well done instructional video, I appreciate you doing this. I was able to follow your steps and replaced my 2016 JK alternator with no trouble at all. Thanks!

Really outstanding instruction and thanks for getting me through my alternator swap. I'm not exactly knowledgeable when it comes to auto repair and when I need something done on a vehicle, I look for instruction videos to help me judge whether or not I have the skillset to do the job with reliable instruction. Until I found your video, I was not sure this job was one I felt like taking on (and possibly messing up). Thanks again.

Awesome video! Quick question, what is the specified torque for the alternator and bracket bolts? Thanks

Thanks for sharing. Your steps were very clear and helped me greatly to help change out an alternator. Thanks!!

Came back and watched this again as my Wrangler needs a new alternator. Great job!

Man… this video was awesome. I replaced my alternator in just over an hour by following this step by step. Had to do it again two days later because I got a bad replacement alternator… But anyways, this video was really clear and easy to follow.

Changed out one today. Thanks for the great video. Helped me with the tensioner instructions.

Very good professional instructions & a nice clean voice during the process of taking off an alternator & replacing it with a new one 👍🏼

Fantastic video. Just installed a 250 Amp Alternator from Michael Singer on my 2016 Jeep JK Rubicon 2 Door. Your video made it very easy. I had to replace the belt with a shorter one due to the overdrive pulley on the alternator. Piece of cake. Thanks for the help.

Thank you, David, your breakdown was right on. Until I watched your video I thought I was going to have to remove the alternator just to replace the belt. The previous four videos I watched on removing the belt never mentioned the triangular bracket under the alternator. Go figure. Even with the two-foot breaker-bar, this old man [70], needed a three-foot cheater pipe on the breaker-bar to push that hydraulic assembly down, loosening the belt to get it back on.

Best repair videos on RU-vid!

Thanks for a great video! Very well done and watching before hand ensured I had no surprises when I completed my repair.

Definitely the clearest and most informative video I've watched.

oh gosh this is gonna be work!! thank you for such a detailed video!!

Great video and it’s great to know all the size tools required in advance. I will be doing an alternator upgrade to my 2017 JK in the near future.

I love your videos, you make it so simple for a person who may not be the best machanic. And when your speaking you don’t bla bla bla .....just straight to the point....Thanks my alternator complete and my pocket book happier!!!!

Great informational post. You do a great job showing and explains what you doing without dragging it out. Thanks again.

Just found your channel in 2022 and you definitely have a new subscriber in me!

torque settings on bolts? (alternator and bracket)

BLOCC….YOU ARE THE MAN 👨. SPOKE CLEARLY, YOUR DIRECTIONS WAS SMOOTH AS BUTTA…🙏🏼🙏🏼👍🏽🤜🏽🤛🏽

This dude’s a real pro. Thank you!!

Thank you so much! My Jeep took a poo today in 100 degree heat

Perfect video to replace the belt on my 2012 wrangler. Thanks !!

Fantastic video! It was very clear and easy to follow. The actual video footage was super clear. Great work and thank you for posting!

The attention to detail is very helpful for a novice like me. Thank you.

Thanks David, your video really helped me see that it's not that hard to do. I'm going to replace it on my 2014 wrangler since the warranty just expired.

This is the best "How to" video I've seen. Thanks!

This was by far the best tutorial video I’ve ever ran into! God you’re amazing at this keep up the great work! You’re helping a newbie like me look like a pro 😂

Thanks so much for making these videos, they're very educational and can help people save a lot of money. Great work. One request...More JK/Pentastar!

Excellent video! I'm actually replacing a water pump on the same vehicle and it looks like I need to pull this off in order to do that.

Wow, this was literally the best instructional video I have ever seen. Well done! Subscribed and Following!

Great video, easy to follow, because of your camera work and explanation. Thanks Friend

thanks for the video changed 2016 alternator today 1hr 1/2

I have watched your video , very well done , i needed to change the belt , wasn't sure if i could do it myself , thanks to you i did it and even did a bit more Keep making video , i also have a 2016 Ram 1500 that will need some brake work Thanks again

Subscribed! GREAT video. Concise, well spoken, I'm impressed! I'll be changing my alternator out later in the week using your video as a guide! Thanks!

2 13s, 2 15s and a 16mm holding it in, yeah, must be a Chrysler. Thanks Dave, saving me tons of money.

Attempting this, wish me luck! Never worked on a car but I don't want to pay almost $600 to have this done.

Thank you for this clear cut clearly spoken easy to follow video. Cheers! Merry Christmas Happy Holidays.

There's always something more difficult than the video shows. On my Jeep, that breaker bar part with the pulley does not want to move. I'm literally standing on the breaker bar and it's barely budging. But was finally able to get it to move but had to put a lot of strength and effort on the breaker bar while my wife moved the belt off and on for me.

Great video! Just finished install on my daughter’s Jeep and it went smooth thanks to the video!!!!

I will be doing thins on my Wrangler with in a few days, this will save me some torment. Good video.

Awesome video and chesty explained. You take great care in getting great video of the steps. Subscribed!

amazing video...I stumped on this video searching for water pump removal

Just know I'm gonna have this video running when I get my new high output alternator! :-)

Keep the Jeep and Cummins videos coming! Thanks!

Very well done. I’m doing this procedure this week. Thanks!

Great step by step video. Thanks

Great video. You do an excellent job of explaining step by step what needs to be done

This helped me perfectly was able to go play by play from the video and it was a breeze

thanks for the great video, and for saving me a lot of money at the dealership.

Great work with these videos.

Nice work! Keep the JK videos coming please. Even if it is "replacing" something that didn't really need to be replaced. JK owners are pretty familiar with that concept.

Dave you do a great job at explaining the process. If I had a Jeep I'd know exactly what to do!

Had to do one of those today. Thank for the video.

That was a fantastic video. Thanks for making this available.

helping a friend save on repair cost, thanks for the great video :)

Very clear instructions

Dude! Awesome video! I think I’ll save the money on labor.

WOW....You teach very well !

Thank you for the excellent video - clear and simple advice that even I can understand - keep up the good work!

Is it really necessary to remove the triangular bracket? I think you can just remove the two long screws holding the alternator to the engine and the two short screws holding the alternator to the triangular bracket. Thus leaving said bracket in place.

Just want to say thank you show us these video

Thanks for making this video well explained.. through out step-by-step.. made my job very easy..thanks again👍🏻

Simply awesome you are great and excellent details, great teacher , thank you more jk please
