To provide a vehicle that can restrain excessive temperature rise of a high-pressure fuel pump even at the time of coasting travel and at the time of stoppage of an engine.SOLUTION: A vehicle according to one embodiment of the present disclosure comprises: an engine; a high-pressure fuel pump arranged in an engine room together with the engine; a water-cooled intercooler cooling circuit constituted so as to include an electric water pump arranged in the engine room, a water-cooled intercooler through which a refrigerant from the electric water pump flows, and a subsidiary radiator through which the refrigerant from the water-cooled intercooler flows; and a pump water cooling circuit for cooling the high-pressure fuel pump. The pump water cooling circuit branches from the water-cooled intercooler cooling circuit, passes through the high-pressure fuel pump, and is connected to the subsidiary radiator.SELECTED DRAWING: Figure 1
