Tesla Model S/X Coolant Pump

Overview:

Both the Model S and X use a very capable (but curiously unbranded) coolant pump. Internet research (https://www.diyelectriccar.com/threads/the-teslorean.170770/post-856074) seems to indicate it may be made by a VariMax, though there are so many Tesla part numbers it's hard to say which actual model it is.

In ICE circles, this pump is commonly used in high performance intercooler systems, so Lingenfelter Performance Engineering has compiled a fairly thorough (though questionably formatted) datasheet on the pump (https://www.lingenfelter.com/PDFdownloads/L330070000.pdf). Another fairly thorough overview can be found within the EV Create overview of the Tesla cooling system. (https://www.evcreate.com/using-tesla-thermal-management-system-parts/#tesla-pump)

Issues

Annoyingly, the bearing is integral to the impeller, so if you have a noisy pump there is no way to replace just the worn part.
