A cooling device is employed in a vehicle including an internal combustion engine provided with a forced-induction device and an intercooler. The cooling device includes a circulation circuit configured to circulate coolant supplied to the intercooler, an electric pump configured to operate to circulate the coolant in the circulation circuit, and processing circuitry configured to control a discharge amount of the coolant of the pump. The processing circuitry is configured to execute a control amount deriving process of deriving a control amount of the pump based on a requested flow rate and a coolant temperature, and an operation process of causing the pump to operate based on the control amount when the requested flow rate is larger than 0.
