GM’s new series of Ultium Drive electric motors
Are these liquid cooled? There's what looks like a fill cap on top? Do they need a separate radiator?

If it’s like a Tesla, it is liquid cooled but the system is much more sealed. Tesla recommends changing your coolant once every 150k miles.

Chevy Bolt (a GM EV) has three cooling coops, with three water pumps. (Electronics/motor, cabin heat, battery)

Identical 150k coolant change interval.
