2011-2020 Toyota Sienna Alternator Replacement DIY 

Dude. Who are you? A professional mechanic? A professional videographer? Your work is amazing. The video editing, wow, every step clearly shown with a caption/label and video chapter and the whole thing is LESS THAN 11 MINUTES (about 7 for the tear-down)! I made my 9 year old son help me (mostly to pause and rewind your video with his cleanish hands) and we knocked this out. This job would have been crazy hard for someone just trying to figure it out as they went. The two bolts that were mostly by feel, my son was like, "how did he even get this on camera?"

If RU-vid ever establishes a RU-vid Hall of Fame, this video should be in it. It is the golden standard of how to produce and edit a vehicle repair video. This 11-minute video saved me $1000 yesterday.

This video should be taught in schools. The perfect RU-vid How-To car repair video. No fluff, no words, just right to it with perfect view of what to do and how to do it. You sir are the GOAT.

Thanks dude! I was quoted $1,100 at Firestone. I got all the parts for $300, and got it all fixed in my driveway thanks to you. You saved me $800! Rock on

This has to be the best video on RU-vid. No talking about your day, just straight to the point. Thank you

I’m commenting as the wife of red rocks. This perfectly executed video saved our Fathers Day weekend. I am so grateful my husband found it!! Not only did it save us at least $1000, but the time! We are now on our way to the river, instead of working on the car all day. Thank you for your time and effort in making this!!

Excellent in all respects. Showed me exactly what to do and in what order. And perfectly edited with no unnecessary small talk, opening or closing buffers. Perfect video. Thank you!!

This is what everyone wants in a RU-vid. God bless you sir.

I owe you at least a comment. You did a fantastic job showing everything that I needed to know, and the labels were extremely helpful as well. A $900 job at the shop turned into a $200 weekend project, and I get to keep the wobble sockets and the radiator bleeder funnel!

I wish Toyota made it easier accessable to get to the Alternator, to save so much time on removing so many things. But thank you for making it clear on how to tackle a pretty tough job for non mechanics like myself.🙏🏾

Absolutely legendary editing and filming. I rarely comment on these videos, I just use them, benefit off them, and keep moving. However this is some phenomenal editing thank you very much for your service.

Best auto repair video I've ever seen. This makes me want to actually change the alternator on my car instead of take it in. Amazing!

Tried valiantly to take the alternator out without removing the fans but failed. Definitely wasn’t that difficult to pull the upper rad hose and the fan assembly. Then the work is much easier. Got away with not removing the lower rad hose tho, keeping most of the coolant in - if that matters to anyone. Great video thanks for good lighting and descriptions along the way. Perfect help.

I just wanted to echo some of these comments. Excellent how to video. Finished the job, not too bad. Took 4 hours but I was also chasing kids 🤷‍♂️ Well done sir!

I know this is an older video, but this video is 100% spot on and perfect no fluff video. Much appreciated. Only thing I'd add is don't tighten the two 14mm alternator bolts all the way on the front of alternator until you get the hidden 12mm in and tightened. just makes it a bit easier. Other than that everything is perfect.

This is so far the best video for Sienna alternator replacement - very clear step-by-step directions and high quality video. I have a 2011 Sienna that will have the 2nd alternator replacement soon. Lot of remanufactured alternators are not Denso and will not last long. Keep the original alternator and have local shop to recondition it if possible.

That was by far the best instructional how to vid i've seen. Without the chitter chatter stories telling crap. Excellent work my friend. thank you

Thank you won’t be enough to appreciate your explanation and video. I was able to replace the alternator for the first time and save money with Towing and labor. Also I lost the fear of fixing simple things we consider sometimes a nightmare. I would give you a thousand likes but I am not allowed but as an appreciation I am now subscribed to your channel.

Awesome. Just awesome. I don't know anything about fixing cars I did this in about 4 hrs with your video. It would've taken me days on my own. And putting the tape on the bolt so you don't lose it, genius. I would've lost that bolt 50 times trying to put it back in. And you did it all without talking and explaining stuff for 35 min. Just incredible. Can't thank you enough

Probably the best automotive repair tutorial I've ever seen.

Great vid MrR. To the point, it made it less stressful having an idea of what to do. Nit a mechanic by trade, 3hrs, no nicks. Haha. Thx bro!!

Incredible! I just spent a few hours following your step-by-step tutorial and replaced our alternator. Thank you so much!

I having a working van because of you!

Best mechanic’ video I’ve ever seen! Not a second of my time wasted, clear and right down to the point! 👍👍👍

Thank you! I don’t think I could have done this without breaking something. Your video helped tremendously.

Thank you very much, I couldn't do this DIY without your specific video. The other videos didn't work for me.

Dude, this is the best how-to video I've ever seen. Very helpful without the 3 hours if describing,,,just did it. Thank you. Definitely subscribing

I pretty much never comment, like or subscribe. This channel a/ video saved me so much time! Remove and replace in under 2.5 hours. including 2 drives to the auto parts store.

I can definitely appreciate the time you took in putting this how to together, very thorough! Our Seinna's gave up 3 hours away from home amd fortunately the battery lasted long enough to get us safely off the highway... Fun day ahead LOL but your video preps me for it!

This looks the same as a 2009 almost. It's the best video on how to do all of the Toyota's Sienna's!!! WOW

Thank you very much. Im changing an ac flow sensor but wasnt about to damage the wiring connectors wirhout knowing how. That 10 mm bolt under the boot and the standard connector makes it possible to remove C clip and sensor with room to move. Kudos to you and thanks again.

Thanks brother for the real good details. Teachers like you are awesome they break it down smooth and clean thank you my brother

After returning core, did this in 4 hours for $300. Happened to be a surprise while I was out of town - could've ordered from RockAuto to cut cost to $200. Great video! One tip I found when reinstalling the alternator, don't tighten everything down at first. Doing the bracketed (lower right) side first helped get it seated correctly.

Thanks just completed this on a 2011 Sienna SE. The lower bolt on the alternator gave me the most trouble going back in. It mostly done on feel to start the first few threads. Thanks again.

Thank you for a fantastic video MrRangerZR1: good clips, captions & editing - no nonsense. My sons & I knocked this out in a few hours today thanks to your help!

Great video. I paid $1400+ last year to replace it for 2011 Sienna (bay area). Sigh.

Thank you for all the work that went into this.

Awesome Video, The best out here. Thank you. I am fixing my 2012 Sienna today by following your step by step. I drain my radiator fluid overnight. probably bleeding them when I'm done. Thank you for your hard working.

Great presentation, every 'how to' video should be like this !

Perfect Video I fix my toyota sienna 2015 all lights came on I check the voltage extremely low not charging I'm replacing alternator thank you for your help

Our alternator gave up while away from home yahhhhh... Luckily O'Reilly wasn't too far, basic tool set and new alternator in hand lol wish me luck!

This was extremely helpful! Used this as a guide to replace the one in my 2011 Sienna. Thank you!

Man you did a great job. I dread having to do this on mine. Thanks so much for the detailed video.

Thanks for the video, what is the best and most informative one I could find. Saved me a lot of money thanks man!🙌🙌

Thank you for your service to all mankind! For me, the bolts information saved my life, and those around me! Thank you

Very helpful vid. My van just broke down

Man it would be awesome if you worked on a 2015 Honda Fit alternator replacement. Anyways great work!! 🏆

Thanks for your professional video and instruction. I replaced my alternator.

Awesome, thank you. We are doing ours today. We'll see if it is as easy as you make it look. Great video.

Great job with this video, saved me a ton of time and money. Very well done!

Felicidades colega me da gusto lo profesional que eres en lo qué haces yo trabajo para Toyota ya x 35 años y es una pasión esta bella profesión saludos desde california

This video is so helpful. Thank you for helping us all. I was able to change alternator with your guidance.

No talking all action love it!

Thank you very much for the video, I did it to the letter and thanks to you I fixed my car

Best auto repair video ever..great job!

This video was a massive help as I had to replace mine this evening. Great video, great detail!

I did this job today and this video was perfect! Getting that little bracket free from the clip and cable ate up about an hour, but besides that, it went well! Thanks Bro!

Amazing video and step by step instructions. Thank you Sir!! 👍👍👏👏👏👏

Nice job showing step by step.

This guy is a fuging hero. All love

this was a big help. my son and I followed step-by-step and successfully replace the alternator. we also left the 2nd coolant hose connected. it made the job more difficult, but kept everything cleaner overall. the only problem is, after finishing the job, the van is no longer starting. it's cranking over, but not starting. any thoughts/ideas? we triple checked every electrical connector etc. I was driving the van (on just the battery) before replacing the alternator. so something happened during or after the install. can't put my finger on it. btw, the battery is fine. UPDATE: we figured out why the van wouldn't start after installing the new alternator. our friend, an experienced Toyota mechanic diagnosed the problem immediately. apparently while removing the old alternator, we jostled the wire too much the leads to the crankshaft sensor down behind the air conditioner compressor. this is the wire connected to the bracket at 7:00 in the video. it's best to remove the bracket from the alternator as he suggests in the video, and then disconnect the wire. our problem was the wire got strained and was loosed from the housing that connects to the sensor, and we lost the connection. this caused the engine to turn over, but not start. so we had to remove the alternator again, loosen the air conditioner compressor so we get access to the crankshaft sensor housing. we crimped the wire back in, and reinstalled everything. the van is running great! save yourself a lot of trouble and be very careful with the crankshaft sensor wire.

Excellent editing. Step by step. Ypu are awesome bro

Amazing video and instructions. I am impressed with your ability to do it all while taking phenomenal video, adding in great written instructions, helpful tips, and no voice over about every little thing. Just excellent video and tip. My only question is this for a 4 (2.5L) or 6 (3.5L) cylinder engine? I hear the 6 is more difficult to get too.

Gracias por tu video muy profesional y muy detallista GRACIAS ME AYUDASTE Y LOGRE CAMBIAR MI ALTERNADOR Y TAMBIÉN ME AHORRASTE MUCHO DINERO GRACIAS 💯💪👍

Excellent walk thru!

Beautiful job and an amazing video!

Good job brother. Thank you so much.

Thanks a million, bro, you saved me lots of money!!!

Amazing at explaining and at video work. Thank you. WOW

GREAT VIDEO! Thank You.

Hey bro this is an excellent video thank you so much keep the videos coming good job and again thank you

Great video thanks

That 12 mm bolt for the bracket, I dont know how many times I dropped it before the a/c compressor. Maybe, I replaced alternator on Sienna/Odyssey 1000 of them. 😂 Good job!

Great job 👍 Respected

💪 bro 😎 you are family now!

Excelente 👌 thanks from juarez México

Hi mr ranger can you do a video on a 2008 honda odyssey rear cylinder head removal and install my rear head is cracked and im trying to fix it I have coolant mixing with oil a tech told me lmk if you have any videos on how to fix this or changing out the rear head 08 honda odyssey j35 3.5 liter. Thanks ive watch alot of you vidz on odyssey you've helped me alot but im not facing this problem to save my vehicle thank you!

very nicely done. great video

Good job .

Very good you help me thank you

Great video, thanks a lot.

Excellent job. At what mileage does the alternator fail? Ours has 130k miles. Changing the alternator in my CX-9 was even worse.

Amazing video

Great video

Much respect Sir. Thanks for that!

Thanks for the help, you saved me an alldata subscription. Lol

Thanks for video

Very good video. I didn’t see how you reattached that wire harness that was connected to the bracket. It seems like it it’s very hard to do once the bracket is on the alternator.

WOW - GREAT - does your video apply to changing a 2008 highlander alternator? If no what is the difference? Is the 2008 harder or easier to change? Thanks

You are my new best friend

Thank u 🙏

Best graphic video!!

Thanks

Good lord. That rear bracket holding the wire. I never got the bracket off the wire. After much frustration then just pushing on the alternator and spinning the bolt while praying,, the bolt to the bracket went in the alternator. My 3 year old said no more work after that today. I hope I didn’t stretch any wires.

Except for the radiator disconnect, this one looked easy compared to the Honda Odyssey

Amazing video! My sister-in-law and I were able to change her alternator by following your instructions. She had no experience and I have limited. It was great!

👍🏻🔥

Did you take the dip stick nut off?

Wouldn’t it be easier to drain the radiator first?

How many miles on it?
