A controlling method for each mode of a variable dividing cooling system performs a heating mode after outdoor temperature and the cooling water temperature are checked when an engine is in a running state and a heater blow (50-1) is in the on-state, and a coolant from the engine (1) is sent to the heater blow (50-1) through a block fluid passage blocking device (40) in the heating mode in order to satisfy heating requirements without performance degradation during heating requirement of a driver. More specifically, engine efficiency and fundamental performance improving fuel efficiency of a vehicle are maintained and expansion of a using region is realized through satisfaction of the required heating performance. |
