Eric...where is your shop located???

Bought the same car a few months ago with 100K and no issues so far.

I would just use a spiral reverse flute tap to clean up the threads instead of a drill bit

in general what is the cost range for the coolant intrusion? (from not bad to really bad) gives us an idea if we bought one with this issue.

I really enjoyed these videos, very informative and a well executed tutorial for non-EV types.

Here 4 part 2. You by passed the manufacturing moisture intrusion fault and provided the ability for oil cooling if necessary ,nice indeed

New sub here hello from down under well presented and explained indeed thank you for taking me along on the journey , am not a fan of EV's though . My I digress and ask these EV's costing 50K to over 100 K and then the thousands it cost for the customer to repair a known seal issue. Good luck with the green side of EV's starting with the carbon foot print 2 produce them them charging them from coal fired power stations , where is the green in that ,some1 is getting conned follow the money , I would never sit on top of a lithium thermal runaway death trap but I digress have been told I do that sometimes but that's just my humble opinion good people. I will see myself out

Awesome job. Thanks for sharing.

Alex thank you for doing this series for the EV community. I have commented before because my Performance S has a high pitched sound but much different than the recored sound in this TH-cam. Mine is much higher pitch. I look forward to your next video where you show how to check the Model S for the coolant issue. I am hoping mine is just drive bearings because like you said, that would seldom lead to a near term catastrophic failure. I'm not driving the car until I can check or get it checked for coolant intrusion. If I don't have coolant, I will drive it from San Diego to you for rebuild, coolant manifold (delete), and ceramic bearings in all spots. I will just fly home and then fly back to get the car when finished. If coolant, I could use your help with safe transport from San Diego to you for the same work and I just fly up and pick up when done and drive it back to San Diego. Do you know if Tesla would do it if I paid them to inspect for the coolant on the speed sensor? That way I could get it done right away. Thanks again!

Great job well done. The only thing I would have done differently was I would have cleaned out the stator far better. It would have shined like new.

Thank you Alex for your very professional take on this specific issues with some Tesla drive units. If I understand you right in what you mentioned in the end of this video, this coolant leakage issue doesnt apply to Tesla mS dual motor versions? I have a 90D, built in September 2016. Does it mean that it doesn´t have this kind of rear motor? What about the front motor?

Is it the metallic whirring?

nice!

Thanks so much World Peace

Thanks so much World Peace

Very good explanation of the issue! In case I had a Tesla that is still under warranty, and found that there is coolant on the speed sensor, do you know if that is a failure covered by the warranty?

Ev cars will poison the planet

Hi Alex, not sure if you done a video on removing the LDU from a model S, I know is done by dropping the whole sub frame but are there any other gotcha points like isolating power and others?

Please explain how you can eliminate rotor coolant (delete manifold) without damaging the rotor.Thanks

👍‍‍👍‍‍

Thanks again for sharing your knowledge. Here in europe we also have issue with bearings / seals for EV motors for the Renault Zoe (2017 R90 motor). I just had them changed at 65k miles at an indpendent shop like yours. Renault dealer only wanted to change the whole motor...

Is it possible to get on a list for a coolant delete part from you? I get the impression they are tough to get from QC Charge - San Diego. Happy to pay in advance if needed. I live more than 85 miles from your shop, so I"d have to trailer my B250E over if I could schedule a time for you to do the delete. I'm willing to try it myself (old mechanic and engineer) and then trailer it over if it exceeds my skills. Great car and good to know it isn't doomed! Thanks.

Thumbs up Do a Video on the Mercedes . 👍👍👍👍👍🍻🍻

Thanks. Can you make a video on how not problematic electric vehicle sounds inside ?

The noise sounds like iX sound effects! 😂

Awesome topic and well done as always! Do the normal drive units get the bearing issue very often? Would love to see the same top issues for the Model S/X battery packs.

You are so helpful and to the point! Thanks!

This is a very interesting explanation of the challenges that are affecting the value of used EV's and this frequent compatabily issues and upgrades are one of the primary reasons as to why I'm staying with ICE.

run the top to the bottum and the bottom to the top manafold

Guessing that failed seal(10 dollar item?) cost the customer on the order of 3k...?? I drove a geo metro...for many years....simple and easy to repair...in the day...I could almost lift the engine out of its bay...Now drive a prius....won't be buying an EV.... you did the best job of explaining a repair that I have seen.....I wanted to see a special device for scraping between the lamination's on the "field" winding...

D.C. to 3 phase ac.. No shade tree mechanic here...Average mechanic can do brakes and axles...little more....

I will anticipate the next video as I find this so entertaining and educational....Javi G.

Compared to an ICE engine the Tesla motor is relatively easy to remove without many parts to disconnect. There are several things that need to be removed to get the motor out but nothing like removing fuel injection, alternator wires, spark plug wires, several belts along with worrying about gas lines full of fuel.

That's a crazy place for the disconnect, something that's very important to have easy access in case of fires and other issues.

Excellent video I just wonder what the parts and labor cost. Whenever you have new technology, you have new problems!!Cooling water leaking into the electric motor, what a hassle and a headache and expensive

Totally blown away! Such a complex process, and you make it look so easy at the same time! My deepest admiration for what you do, and hopefully you'll inspire many young adults, like yourself, to take up a trade like this! We will need them, lots of them! A++ on the video narrative as well!

Quality content! Thank you for answering so many questions in the comments!

wow!

What happened to the none corrosive aluminum coolant designed just for aluminum motors?

wow

yes

wow

Great repair. I would love to have you as my mechanic. Your diligence during repair is outstanding. I imagine the labor repair cost is inline with replacing an ICE engine but the actual parts cost is minimal compared to an ICE car. Great video as well showing every detail!

I find EV are easier to maintenance than ICE from this clip.

Your skills are very impressive. Everyone can see how the auto industry is changing right before their eyes. You are not just a mechanic like in the old days - you are an electro-mechanic. Thank you for sharing your knowledge with us. Your skills are truly impressive. Would you mind telling us how much that repair cost? Also, have any cars returned for a second time with a coolant leak? Thank you.

I can always spot a good mechanic by how methodical they are. Nice job sir.

Green loktite is self wicking. You should read the instructions on the bottle but you can just put the bearing in and then go around it with the green locktite to seal it in there. And save some rtv for the rest of us!

Have you ever thought about doing a Professional video where you include the torque values and actually talk through the minor issues of these rebuilds? Your video covers a lot of the particular issues, but I'm sure that there's many things that you didn't cover. I'm thinking that you could cover that in a Patreon type of video for guys who want to graduate into working on these cars, since EV cars aren't going away and are going to become more common. My son-in-law is a very experienced transmission rebuilder and so he might be the very audience that you could appeal to.

At 25:00, My only suggestion would be to get yourself some brass hammers and brass punches for reinstalling the bearings. They will give you a much better "feel" for the installation. I'm an OG machinist. I'm interested in the overall costs to the customer for your 1st rate rebuild!?

At 51:00, I'd suggest that you place some soft copper stripes on the housing that you're prying against to remove the smaller gear. Otherwise, I've been enjoying the rest of the video! You're a VERY gifted mechanic and I'm very impressed with your knowledge and professionalism with this issue! The bigger issue is WHY they haven't addressed the issue of a "known" coolant leak issue on these cars!
