Abstract

A cooling system (1) includes a cooling portion (2) for flowing a coolant therethrough, a coolant sensitive sensor portion (3) detecting a temperature of the coolant, a heat exchanging device (4) using a heat of the coolant, a circulation flow varying device (5) for varying a circulation flow, a circulation path (6) for flowing the coolant therethrough, and a controller (7) for regulating the circulation flow by controlling the circulation flow varying device while referring to the temperature of the coolant upon a receipt of a request for a requested flow from the heat exchanging device. The controller (7) determines a condition for warming-up when the warming-up of the engine is performed in accordance with the temperature of the coolant, controls the circulation flow varying device for warming-up the engine without circulating the coolant, and increases the circulation flow to the requested flow for a predetermined period of time when the requested flow is requested during the warming-up.
