Abstract
An engine cooling structure includes a head gasket sitting between a bottom surface of a cylinder head and a top surface of a cylinder block, a connection water passage for coolant that connects an in-head water jacket and an in-block water jacket to each other, and a reed valve that opens and closes in correspondence with a differential pressure of coolant in the in-head water jacket and coolant in the in-block water jacket. The reed valve includes a reed portion arranged integrally with a part of the head gasket corresponding to the connection water passage.
