Tesla LDU Rotor Coolant Delete Install (Model S)

In this video, we install a rotor coolant delete manifold on the Large Drive Unit (LDU) in this 2014 Tesla Model S. Almost all LDUs are prone to a failure of the rotor coolant seal, which ends up leaking into the motor with the potential to cause catastrophic damage to the drive unit.

The LDU is equipped in pretty much all RWD and/or Performance versions of the Model S and X from 2012 to early 2021 (dual motor, non-performance models are unaffected).

If you are looking to get a coolant delete manifold installed on your LDU equipped vehicle, or have any other powertrain issues with your EV, feel free to get in touch!

Well made, information is clear, no stupid music.

Very informative. I watch South Main Auto and Rainman Ray’s ICE repairs, and your cv removal is very similar. I wish I were younger, I like EV repair a lot. Hopefully a lot more shops starting doing this kind of service. You could teach at a tech school.

Hopefully good & honest ICE mechanics will realize that switching to EV repair can be a very lucrative field and not nearly as messy.

I have never worked on an electric vehicle, and I am looking at videos like yours because I might buy a Tesla in the future but by the looks of it it will be very difficult to do what you did without a lift, you made it look easy but I am pretty sure it is difficult. Great video.

Thank you for the great video! One thing I would suggest mentioning is to mark the position of the bolts on the subframe before removing it, so that when reinstalling it can be put back into exact same position. Otherwise alignment may get affected.

That is without doubt the most concise video work of subfame drop / coolant delete Ive sen to date thank you. Ive run a Model S P85 from new now 10 years old 155, 000 miles. About 100, 000 miles I cut a 2" 100mm hole in the plastic cover with a hole saw so I can see the coolant level just by opening the frunk. Ill do a coolant delete on mine in the summer (working outside here in UK) but in the mean time I pulled the speed sensor it was dry, ill keep an eye on the coolant starts dropping start panicking!

I have a tesla 2013 MS 60 with 61, 000 miles. It broke down on the road without any warning indication. Tesla Technician end up replaced the LDU and the half shafts. I also asked to replace the Rear lower control arm and the others upper control arm because I saw other comments on tesla forum about these control arms will break down around 50k-60k. They charged for 5.8 hours of work ($265/hr) and parts, it is total cost for $9, 075. After I watch the video, you make it very simple. Thanks for the video.

A breath of fresh air im a true motor head but only because anything mechanical. Tesla good bad or indifferent changed the EV industry and this is the nuts and bolts of the future.
Thank you for putting a face on EV's.

By 2014 everyone was saying EV maintenance are crazy hard stuff.

2024 combustion cars are almost impossible to repair due labor intensive complexity at a level that makes EV maintenance a school assignment.

Thanks for sharing your work! 👍🌷 keeping older electric cars on the road.

Great video Alex!
Thanks for taking the time showing, which is a quite of a job.

[TeslaTales]

Nice work. Even though I own a 22 M3LR, It's nice to see the older models and how they are assembled.

[BRAAMER]

Do you have a video on the charger inlet? Looking to change it out seeing there’s a bit of plastic that was broke off. I’m thinking you do the same on disconnect the 12 volt battery and the high voltage orange tag connection. Wife has a 2020 model Y. Love the video and I subscribe to get educated seeing I’m going to get a model s in the future. Where do get the delete at?? Great video. I subscribed too.

[knutbar]

great video. Love your narration style. I hit like and subscribe.

[kevinlieb]

Awesome video! Very clear and well done. Thanks!!

[chrisbrookshire]

Great video very informative thanks for putting this out.

[melbatoast]

Hey for ease of servicing later shouldn’t you reverse mount the suspension arms? (Flip the orientation of the bolts) Otherwise basic suspension maintenance is a motor out job.

[mwjoe]

Awesome video. I will be visiting you as soon as my LDU is out of warranty.

[OasisAmps]

I'm always interested in the time the job takes and how much for the customers.

[moestrei]

It's worth checking the direction of the suspension arm bolts on the subframe. Most times they are facing the battery meaning they cannot be extracted easily and reversing them while the subframe is out makes the removal of the suspenion links easier later on. Tesla actually specifies a gearbox oil quantity which ends up to be less than the 'level' plug.
