Claims

[Scope of utility model registration request]

In a V-type engine equipped with a cylinder block having cylinders arranged in a V-shape and a cooling water mantle surrounding the cylinders, a thermostat chamber is recessed in the valley on the top surface of the cylinder block, and a water pump is installed on the end surface of the cylinder block. The impeller chamber of the cylinder block is recessed, and a suction channel connecting the bottom of the thermostat water chamber and the impeller chamber, a cooling channel connecting the water pump outlet and the cooling water mantle, and a bypass hole leading from the thermostat chamber to the outside are installed in the wall of the cylinder block. Provided inside,
A cooling water circuit for a V-type engine, characterized in that a hot water pipe from a cooling water mantle to a radiator and a cold water pipe from the radiator to a thermostat chamber are provided outside a cylinder head.
