I would think water pump, but that looks to be in the rear. It may be electrically driven for when the engine is shut off in the EV mode. It would be a benefit to the engine to pump the radiator coolant to help cool the engine even in the EV mode. Here I am guessing again.

Anybody know about this stuff.
