FIELD: engines.
SUBSTANCE: invention relates to internal combustion engines (ICE) and can be used in ICE cooling system of motor transport and automotive equipment operated at low temperature. Internal combustion engine cooling system comprising coolant-filled channels in body of engine parts, fluid pump, coolant-filled radiator having top and bottom tanks connected pipe grid, wherein upper tank has cover provided with right overflow valve to closing element and spring and check valve to closing element, and is divided by horizontal partition into top and bottom cavities, with hole connecting cavity, wherein partition dividing upper tank of radiator into top and bottom cavity has a seat, in contact with closing element of direct bypass valve, wherein valve spring is attached to cover, which is installed coaxially with seat and is located in upper cavity. Upper cavity of upper tank is equipped with device for visual and manual control of level of cooling liquid. Device for visual and manual control of level of cooling liquid is installed in cover of upper cavity.
EFFECT: invention improves performance of cooling system.
