8. A cooling system for cooling an electric motor, the system comprising:
a fluid loop for circulating a liquid coolant for cooling the electric motor, wherein the fluid loop comprises piping;
a casing of the electric motor in fluid communication with the fluid loop, the casing having a first outlet and a second outlet for removing fluid from a motor casing and an inlet for introducing the liquid coolant into the motor casing;
an accumulator tank in fluid communication with the first outlet, the accumulator tank configured to separate dissolved gas from the liquid coolant and to allow air to escape the accumulator tank; and
a check valve disposed between the first outlet and the accumulator tank, the check valve configured to allow the liquid coolant to flow from the first outlet to the accumulator tank while blocking passage of the liquid coolant with the dissolved gas back into the motor.
