The invention relates to the technical field of vehicle thermal management systems, and particularly discloses a cooling liquid filling and exhausting device and method, and the cooling liquid filling and exhausting device comprises a cooling liquid system, an expansion water tank, an exhausting pipeline and a liquid filling pipeline. The cooling liquid system comprises a warm air core body, a liquid viewing device, an exhaust valve, a circulating pump, a water heating heater and a pressure sensor which are sequentially communicated and form a cooling liquid circulation loop, and the pressure sensor is used for measuring the pressure of cooling liquid in the cooling liquid circulation loop; a liquid injection port, a liquid discharge port and an exhaust port are formed in the expansion water tank; the exhaust port is positioned at the upper part of the expansion water tank; an inlet of the exhaust pipeline is communicated with an outlet of the visual liquid device, and an outlet is communicated with the exhaust port; an inlet of the liquid injection pipeline is communicated with the liquid outlet, and an outlet is communicated with an inlet of the circulating pump. According to the cooling liquid filling exhaust device, the water heating heater does not need to be started in the exhaust process, then the water heating heater is protected, the exhaust result can be detected, and the exhaust reliability is high.
