Tesla LDU Rotor Coolant Delete Kit withBillet aluminum Barbed Fitting. The barbed fitting is CNC cut from 6061 aluminum.
This kit deletes the coolant from the LDU rotor preventing the inevitable leak that will destroy the Tesla Large Drive Unit.
This kit can be installed in car without removing the drive unit or subframe. There are two installation options: Removing the coolant pipe completely, or only removing part of the pipe (which is usually easier). The kit contains the Billet Aluminum barbed fitting, two o-ring plug fittings, a return tube cap, and a casting plug.
Notes:
The return pipe that is deleted along with the coolant flow to the rotor originally sent the Heated coolant to the differential where it rejoined the heated coolant returning from the stator/inverter. Some people have concerns that the small amount of heated coolant is necessary to cool the differential/gearbox.
Installer Modifications:
If you desire to repurpose the rotor return pipe and send Cooled coolant to the differential, The barbed fitting is designed with a flange that can accommodate a 1/8" NPT fitting. The barbed fitting flange needs to be drilled and tapped with a 1/8" NPT tap. Additionally, the fitting on the return tube needs to be cut off of the tube and also tapped with a 1/8" NPT tap. Barbed fittings with a hose, or air fittings with plastic tubing both work. See pictures on where to drill and tap using a 1/8" NPT tap.
