Zusammenfassung:	The invention discloses a control method for an engine cooling system. The control method comprises the following steps: (a) initializing an ECU (Electronic Control Unit); (b) reading the temperature of cooling liquid in the engine cooling system by using the ECU, and comparing the temperature of the cooling liquid with each temperature threshold value to carry out the corresponding operations as follows: when the temperature of the cooling liquid is smaller than T0, a water pump runs at a low speed, and a cooling fan does not to work or works at a low rotating speed; when the temperature of the cooling liquid is greater than or equal to T0 and smaller than T1, the water pump runs at a higher rotating speed; when the temperature of the cooling liquid is greater than or equal to T1, the water pump runs in a full-coupling manner; when the temperature of the cooling liquid is greater than or equal to T2, a thermostat is started initially; when the temperature of the cooling liquid is greater than or equal to T3,
