PROBLEM TO BE SOLVED: To provide a vehicular cooling device that can secure cooling performance of a high-temperature radiator 4 for cooling an engine and can maintain acceleration response and intake air cooling performance during operation of a vehicular air conditioner.SOLUTION: A vehicular cooling device includes: a water-cooled intercooler 6; a condenser 2; a main low-temperature radiator 3 for receiving wind flowing in the condenser 2; and a high-temperature radiator 4 for receiving wind flowing in the main low-temperature radiator 3. The vehicular cooling device further includes: a sub low-temperature radiator 1 for receiving wind that does not pass through the condenser 2; and a low-temperature water circuit 7 for making a circuit of the sub low-temperature radiator 1, the main low-temperature radiator 3 and the water-cooled intercooler 6. The low-temperature water circuit 7 includes a flow passage change-over valve 9 for switching between a flow passage for flowing intercooler cooling water while bypassing the main low-temperature radiator 3 and a flow passage for flowing the intercooler cooling water through the main low-temperature radiator 3. |
