Engine cooling device

An engine cooling device comprising:

• a block lower portion that is a lower portion of a cylinder block of an engine;
• a block upper portion that is an upper portion of the cylinder block;
• a cylinder head of the engine;
• an exhaust cooling portion that cools an exhaust gas of the engine;
• a radiator that dissipates heat of a coolant;
• a first path that bypasses the radiator to cause the coolant to circulate through the block lower portion, the block upper portion, the cylinder head, and the exhaust cooling portion;
• a second path that bypasses the block lower portion to cause the coolant to circulate through the radiator, the block upper portion, the cylinder head, and the exhaust cooling portion;
• and
• a flow rate control mechanism that increases a flow rate of the coolant flowing through the second path with respect to a flow rate of the coolant flowing through the first path when a temperature of the coolant flowing through the first path is equal to or more than a warm-up completion temperature, as compared to a case in which the temperature of the coolant is less than the warm-up completion temperature.
