- In this video we feature another new product from Revolt Systems, the Coolant Delete kit. Eddy breaks down a common issue we have been seeing in Tesla LDUs & explains how this product bypasses that issue if caught in time. Snow also does a live demonstration of how fast it is to install this product once the LDU has been removed.

![[DIY] Tesla LDU coolant leak fix story](/img/n.gif)
Leave it to the hotrodding community to always come up with solutions the engineers were clueless about.
Awesome, we've been looking for a solution to this issue to include with our ready-to-run Tesla LDUs. Great work, I'll be reaching out soon. Thanks!
I understand at You just stopped cooling. How it goes without cooling of drive unit?
We still cool the entire motor. This is just a bypass for the problematic seal.
@@revoltsystemsyou need to provide more details around the cooling of the unit after the delete. Please think about an additional video related to this topic alone. Thanks, Ken
Compessed air? To cool it with air? An an exchange unit to transfer that heat to the coolant? But that's not one simple trick they can sell... Now I cast that idea to the big players that can make it, I'll see it in a few years being made, and shrug my shoulders at it.
Desert Storm guy can be an expert at this because he served. No disrespect. It's all in the balls someone's willing to put in their early years.
I had a notification on my dashboard that I should contact Tesla service center when I did I guess they ran a diagnostic on the car over the Wi-Fi and told me I need to bring the car in and they're going to swap out the rear motor on my 2019 Model X performance, even though I wasn't having any issues driving around or noises, they replaced it within a couple hours and off I went. I'm guessing maybe some sort of sensor said it was leaking inside and maybe that's why they replaced my motor even though it was running fine? Rear motor that is.
$550 for $12 worth of metal? Is NASA making this? How about $75? These motors are on eBay for $1500 not $5000. You are inflating the cost to sell this nice, but overpriced piece. I got an out of warranty quote to replace my small front drive unit from Tesla and it was $6400 and included axles ($1k) and labor.
You should start a business or run for office.
🤗GREAT IDEA 💡 FOR ALL,THANKS FOR SHARING THIS INFO ℹ💚💚💚
Wouldn't it cause excessive heat in d Rotor/Stator of d LDU if d cooling effect is taken away? How will it affect reliability of d LDU in d long term or on hard drives?
No excessive heat. Actually this was not intended to cool the rotor. We have a new video coming soon to address this question.
@@revoltsystems Where is that video, love to see how you think that loop isnt for cooling the rotor....
Looks great!
You got one coming your way now. Let us know how it works out.
If the speed sensor is corroded and moisture present is it too late too add this delete kit?...took the car to tesla all they replaced was a speed sensor and wouldnt wven address the ldu bc it passed moisture and isolation tests ...so i was left with no peace of mind and a band-aid ..cars out of warranty
This is awesome! I just got a low mileage p85 and was worried about this issue.
Холодный воздух имеет больший проходной путь внутрь ротора с распределением раздува внутри по всей полости,соответственно не будут грется подшипники ротора,это полная безопасность!
Я рад что ребята такое изготавливают,но ограничение ротора в охлаждении чревато нагрева оси ротора,а там подшипники,но все тоже от оборотов двигателя зависит,соответственно подшипник греется и идет износ,постоянная подача охлажденного воздуха решает эту проблему!
Spaceba!
That is too bad I can never find my 10 mm socket. 😊
HA!! the old 10mm
G'day gents, my 2015 model 85 has a large rear motor, so far, so good, only 40,000 km on the clock. Just wondering if you recommend the coolant delete for my car. And do you sell these? Cheers from Australia. 119 liked and subed.
We absolutely recommend the bypass kit. you can get one from our web site. Get it on before it floods your inverter.
I don't subscribe to many channels but this one has quality content that is well presented. I am subscribing. Only wish you were here in Australia...😢
Ah man, we appreciate that, & thanks for tuning in. More videos on the way for you this week 🙌🏽
Just hit 82,000 MI on my performance X I'm looking at this part real hard cuz I really love my x and I think I want to keep it. I only trade it in for 5-seater plaid X but there is no such thing.
Get it done before its too late. The Plaid does not have the same issue.
Glad to see out of the box thinking and engineering to solve the issue.👍👍.Not sure if M3/MY have this issue.
Hopefully the clones don't nullify the hard effort put in, before sufficient return for the time/effort. Should definitely implement an etched unique barcode(a low power fiberlaser should do it), to keep track of the original units. Wish you guys great success, and let us know, if there is similar upgrades to M3 to improve troublefree service life.❤👍
You should be good on the Y and 3, those motors are oil bathed and have a totally different cooling system.
The best seal is no seal. Sounds like the rotor will no longer get liquid cooling with this delete kit, but apparently air cooling to the housing from it spinning suffices. Wonder why Tesla never tried that during development since a liquid seal on a high-speed shaft was surely of concern for reliability, including warranty repairs.
We still cool the entire motor and this kit just bypasses the rotor that does not need it. Tesla is doing this in the new "U" version of the LDU
@@revoltsystems Great. I saw earlier youtubes from a company which re-engineered the seal design and offered a retrofit if you ship the LDU to them. But, perhaps didn't prove much more reliable. No seal is best. Perhaps the biggest concern is if the rotor warmed past the Curie point of the permanent magnets in the rotor, which would ruin them. If so, then Tesla would have major recall problems, but appears that isn't a concern.
Hi. I drive an older 2018 Long Range rear wheel drive model 3. The rear drive unit is giving me an error code: DIR_a149.
I’ve been to Tesla service before and they topped up my coolant. Fortunately I’m still under warranty. But the error returned. Just a heads up that we may have an issue with high mileage model 3s
That' seems so wrong. If the coolant was low, it had to have leaked somewhere. If it is in the motor that 's huge trouble.
@@NackDSP update: the second time I took the car in, a tech identified my problem and sent a picture showing rodent damage. They chewed through my coolant lines and into my high voltage cables. I had to replace a wiring harness and coolant lines.
Looks easy, except for the part about pulling the motor out of the car.
Or can this be done without pulling the motor out of the car?
No
Much easier than pulling any ICE out. I just did it.
I agree, its a day job.
Tesla needs to provide a fix for this if its is a problem.. A recall
They have a new version of the LDU with the letter "-U" at the end of the part number. This has a similar bypass that we make.
Does the leak occur at 50,000 miles?
Could happen at anytime. Seen anywhere from 30K +
Я придумал новое охлаждение ротора,не изготавливая ваших заглушек!просто подать фреон воздух в нутрь ротора,Маск это знает,но молчит!
So no more rotor cooling. It gets very hot now, the grease melts out of the bearings and they fail? I mean Tesla had good reasons to cool those rotors. In the Small DU they switched to oil cooling but they still cool the rotor.
Been driving with one for some time now in a race car that is pushed much harder than the daily driver will ever do. No issues and the LDU did not cool the rotor enough to make any impact. They tried to use the heat from the rotor to normalize the temperature in the gear box, this also was a design flaw by Tesla.
How many miles you have or have seen on the deleted setup? Thanks, Ken
Are guys (sound like Californians) in Oceanside, CA? Do you do the work if someone brings you a pre-leak Model S P85D? I would like to just drive mine to you and drive it away with this kit installed. How do I get in contact with you? Are you in anyway affiliated with QC Charge? (see their reviews...). If you don't do the work, but sell the bypass kit, where do you recommend someone takes their car for the install?
We are not at all associated with QC Charge. We don't do the work but can recommend some great shops in our area. feel free to email us and we can get you setup.
We received our first ReVolt coolant delete kit today and a little box of candy NERDS! Install is next week and we will post pics.
Can’t wait to see it! If you post on Instagram, be sure to tag @revoltsystems 🙌🏽
Was there ever a factory fix for this issue? And if so, on what date or Serial Number was it implemented?
Thanks for the great video!
Look for a "-U" at the end the part number on the drive unit. Those have the factory bypass.
It's great. Can you do same with mercedes EQC motors.
Yes it will bolt up with no issues.
can you send to spain ?
Check out EVXPLORER they are in Zaragoza, Spain
Yes, just need to pay extra for shipping.
So you're not bothering to dry that unit out?
Some are just too bad and have isolation issues.
Do you guys offer the installation???
We don't but know of many shops that can.
Is it possible to do it without removing motor ?
Unfortunately no
Interesting idea, but I can't help but wonder about the downside of losing the ability to liquid cool the LDU. I suspect that there was a reason that the manufacturers of large AC motors add liquid cooling.
Drive like an old lady and you may be fine 😅
The stator and inverter are still cooled. Just the rotor is bypassed since the seals are extremely problematic and prone to leaking coolant into the stator windings and inverter. These are some of the earliest Tesla motors and have a few engineering flaws. Their new motors use ATF to cool the stator and rotor. Eliminating the problem.
@@J5Jonny5Do you have any stability or real time data on long term effects of not not cooling the rotor? Thanks, Ken
@@J5Jonny5 Please advise us on how the ATF solution fixes a bad seal issue? Does it now leak ATF into the motor and inverter when the seal goes bad?
@@Roadstercycle From what I've read ATF doesn't harm any of the components it gets on. So yeah, sounds like it can still leak but ATF won't short out the inverter or cause rusting.
What if we switch to oil cooling?
You would have to flush your entire system out to get rid of ALL the G48. It can be done but good luck.
I’d just separate the motor and inverter cooling loop from everything else.
How do I order?
You can contact us via our web site. www.revoltsystems.com
Can this be done with drive unit in the car
It looks like the trick is getting the long tube out of the motor. There isn't clearance to do it with the motor mounted in my car. It would seem that a determined person might be able to pull that original cover off and away from the motor an inch until it hit the car structure and cut the tube, pull more out, cut it again and repeat until the whole tube is out of the motor. Great care would be required to avoid metal bits from getting into the exposed motor.
Unfortunately you need to pull the sub frame down. We were able to do it without removing the motor from the axles but still needed to pull it down.
