Our Coolant Delete prevents inevitable damage to Tesla Large Drive Units ("LDU", formerly the "570A" motor) from leaking rotor seals found in the Tesla Model S, Tesla Model X, Toyota Rav4 EV, and Mercedes B-Class.
This leaking coolant issue will short out the stator (field windings), seize and rust the rotor, and complete destroy the electronics in the inverter.
After rebuilding hundreds of these Tesla Large Drive Units ("LDU"), we have developed the Coolant Delete to permanently prevent the problem for ever occurring. The QC Charge Coolant Delete works in the same way that Tesla adopted to address the same issue on LDU's in 2021.
This Coolant Delete will allow the Tesla LDU to operate with the following parameters
- Allow for oil cooled Rotor. While the rest of the components are cooled with the same G48 or other coolants, the rotor can be specifically cooled with Dexron VI or 212B gearbox oil. Using oil cooling will require additional parts (not included). In this operating mode, if the rotor seals were to leak, Dexron VI or 212B is benign to the LDU. It will not destroy the stator, it won’t seize and rust the rotor, and it won’t short out the inverter. This operating mode is intended for high performance LDU applications
- Remove Coolant from the rotor. This is the same functionality as the "Coolant Delete Lite". Coolant is not allowed to pass into the rotor, thus addressing the failure mode which can destroy the stator and inverter.
- Importantly, the QCCharge Coolant Delete preserves the coolant line to allow for coolant to still reach the gear set and the inverter chiller plates. Other competitive options do not keep this important part of the cooling loop!
