The invention relates to a cooling adapter. An inlet portion (8) configured to cause the coolant to flow into the water jacket of the cooling adapter (1) is provided to open at a position close to the cylinder head (2). Therefore, the area on the exhaust outlet side of the cylinder head (2) can be effectively cooled by the cooling adapter (1) and the amount of thermal expansion that can be maintained in the region is small. In addition, the aforementioned inlet portion (8) is also provided to open at a position corresponding to the gap between the adjacent exhaust passages in the exhaust passage (4). Therefore, from the entrance of (8) low temperature cooling liquid flows in the water jacket may exhaust flow channel in a water jacket (4) between the adjacent exhaust channel in the region, the heat exchange between coolant and exhaust and may not be there. The efficiency of cooling the exhaust gas in the cooling adapter (1) can be correspondingly prevented.
