In an engine cooling control device configured to return passed cooling water to the valve casing side; an oil cooler return passage for returning cooling water from the oil cooler and a heater return passage for returning cooling water from the heater are independent from each other; , Cooling water flowing into the valve casing from the oil cooler return passage flows toward the temperature sensing part of the thermovalve, and cooling water flowing from the heater return passage directly flows into the outflow port of the valve casing. An engine cooling control device that directs the flow toward the downstream side.
