Tesla Motor Coolant Seal: DIY Failure "Investigation" and Replacement

In this episode, I replace the Tesla Coolant seal in the motor. Learn and do better 😀 Updates 1) Heat the aluminum manifold in the oven to 250°C before seal insert! Thanks to @TSINED1. Edit: around 125°C (~250F) may be better due to the lower chance of damaging possible adhesives /sealants (between the manifold and the pipe and/or in the seal). Or use a hydraulic press with a helper pipe. 2) way less sealant should be used (just a thin film) compared to what I did. Thanks to @Al Savage 3) Maybe it is acceptable to have a bit of damage on the excluder lip, so maybe I spent too much attention to that? 4) Why sanding with such a narrow strip of sandpaper: I wanted to keep the "unpolished" shaft parts in their "original" state for in case my sanding made things worse. 5) My assumption of a worn-out seal may be incorrect: The measured smaller seal lip tickness may also be caused by the "forming" step (heating and pushing over a mandrel) in the seal manufacturing process.
