The invention discloses a vehicle cooling system and a fault diagnosis method and device thereof. The vehicle cooling system is arranged on the electric vehicle and comprises a temperature sensor and a cooling medium, and the cooling medium is used for conducting heat exchange with power equipment so as to adjust the temperature of the power equipment. The temperature sensor is used for collecting the temperature of the cooling medium; wherein the power equipment comprises a power battery of the electric automobile. The fault diagnosis method comprises the steps that the battery temperature of the electric vehicle and the sampling value of the temperature sensor are obtained, and the battery temperature is provided by a battery management system of the power battery; and according to the sampling value and the corresponding battery temperature, whether the temperature sensor has a fault is judged. According to the embodiment of the invention, the fault diagnosis problem of the vehicle cooling system of the power equipment in the electric vehicle is solved, and the cooling cost of the electric vehicle is saved.
