The present invention relates to an engine cooling system for a vehicle and, more specifically, to an open atmospheric style engine cooling system including a radiator and a reservoir tank. The radiator has a first pressure control cap, and the reservoir tank has a second pressure control cap. An air discharging valve and a cooling water discharging valve prepared inside the second pressure control cap are prepared with springs having different tensile strengths to differently control the pressure of the engine cooling system in accordance with operational zones. Thus, the engine cooling system for a vehicle is capable of maximizing the performance of cooling an engine, preventing an overflow of the cooling water, and easily discharging air. |
