装置。Cooling water is forced by a pressure feeding means through a pressure feeding passage communicating with the lower interior in the vehicle height direction of a water jacket surrounding a cylinder of an in-vehicle internal combustion engine, and the cooling water is forced into a cooling water return passage communicating with the upper interior of the water jacket. In a vehicle engine cooling device including a temperature-sensitive on-off valve, an air bleed passage communicates an upper interior of the water jacket with the return passage near the downstream side of the temperature-sensitive on-off valve; A cooling device for a vehicle engine, characterized in that a bypass passage is provided that communicates the vicinity of the opening in the return side passage of the extraction passage with the pressure feeding passage.
