Abstract

A cooling device is provided for a motor vehicle liquid-cooled internal combustion engine with a radiator connected to the supply and return lines of the engine. The radiator has a filling opening closable by a cap. A temperature-controlled thermostatic valve, via which the coolant is sent completely or partially either through the radiator or through a bypass between the supply and return lines to bypass the radiator, is controllable by electrical heating. An electrical switch is mounted on the filling opening such that upon actuation the thermostatic valve is electrically heated, so that the coolant passes at least partially through the radiator.
