Abstract: A vehicle system is provided. The system may include a first coolant loop, including a radiator, a second coolant loop including a battery chiller, and a centrifugal coolant separator. The centrifugal coolant separator may include a frustoconical hollow body having a base defining a drain and a ceiling defining a spout, and a pair of coolant lines arranged orthogonal to and on opposite sides of the body such that coolant exiting the lines travels along the inner surface and collects at the base to separate gas from the coolant, wherein the spout vents the gas and the coolant exits the drain.
