PURPOSE: An automatic cooling water switching device of a vehicle engine cooling system is provided to prevent malfunction of an engine or an auto transmission and to improve the cooling performance by efficiently implementing auto injection of cooling water into a cooling water line while making a vacuum in the cooling water line using vacuum pressure. CONSTITUTION: An automatic cooling water switching device of a vehicle engine cooling system comprises a cooling water supply part(10), a vacuum transportation part(20), an implantation part(30), and an effluent storage part(40). The vacuum transportation part is connected to the cooling water supply part by a supply line; is connected to the vehicle engine cooling system by an injection line; transfers air for discharging waste cooling water through a collecting line to the vehicle engine cooling system through the injection line; converts the cooling water line of the vehicle engine cooling system to vacuum; and facilitates the injection of the cooling water which is stored in the cooling water supply part in the vehicle engine cooling system through the supply line and the injection line. |
