Abstract
The cooling device is provided with an engine including a cylinder block, a cylinder head, and a W/J which is a single system as a whole and which causes coolant to flow from the cylinder block to the cylinder head. The W/J branches into first and second inner paths within the cylinder block, and joints together within the cylinder head. The first inner path is provided with an opening and closing valve for permitting and prohibiting the flow of the coolant based on the pressure of the coolant.
