It has been difficult to manufacturing a cylinder head having an EGR gas cooling structure which has high cooling performance and can be easily configured. A cylinder head having an EGR gas cooling structure is configured in such a manner that a gas passage which guides to the air intake port side a part of the exhaust gas discharged from the exhaust port is disposed within the cylinder head water jacket to cool the exhaust gas flowing through the gas passage. The gas passage comprises a cooling section which makes contact with the coolant within the cylinder head water jacket, and also comprises a hollow pipe which has high-strength sections located at side portions of the cooling section and having higher strength than the cooling section. The high-strength sections of the gas passage are molded within and surrounded by the cylinder head.

The cooling water temperature sensor detects the temperature of cooling water that cools an engine. The estimated temperature calculating unit calculates an estimated temperature, which is an estimated value of the temperature of the cooling water. The determining unit determines if the thermostat has become stuck open after warming-up of the engine is complete. The criteria whereby the determining unit determines that the thermostat has become stuck open are that the estimated temperature is higher than a stuck-open determining temperature, which is a temperature lower than a warm-up completion temperature indicating that warming-up of the engine is complete, and that the cooling water temperature, which is the value detected by the cooling water temperature sensor, has been continuously at or below the stuck-open determining temperature for a determination period. 1.
