PROBLEM TO BE SOLVED: To provide a method for extracting engine cooling water, through which engine cooling water residing in a disposal vehicle can be extracted with high extraction rate and in a short time. SOLUTION: An engine cooling system comprises a radiator 3; an engine cooling water passage 2 connected to the radiator through a radiator upper hose 4 and a radiator lower hose 5; a heater core 11 connected to the engine cooling water passage through a heater upper hose 12 and a heater lower hose 13; and a reservoir tank 8 connected to the radiator through a reserve hose 9. In a method for extracting engine cooling water residing in an engine cooling system, an attachment 20 for suction is inserted in the radiator hose 5 with a cap 7 of the radiator 3 and a cap 10 of the reservoir tank 8 closed and engine cooling water residing in the engine cooling system is sucked. Thereafter, the heater core upper hose 12 is cut and an engine cooling system is released in the atmosphere and further the engine cooling water residing in the engine cooling system is sucked.
