Abstract
A cooling apparatus for a V-type internal combustion engine has a water pump disposed at a central portion of a front end surface of an engine cylinder block. A cooling water inlet passage, provided between the radiator and water pump for introducing cooling water into the water pump, includes an external pipe extending along the front end of the engine cylinder block and turning into a V-shaped space defined by and between elongated first and second cylinder banks set at an angle relative to each other and an internal passageway formed in the cylinder block. The internal passageway has one end communicated with the water pump and its other end opening to the bottom of the V-shaped space and connected to the external pipe.
