PURPOSE: A coolant supply method of a coolant flow path in a throttle body is provided to prevent the ignition time from being delayed due to the rising temperature of intake air passing through the throttle body by controlling the coolant supplied to the coolant flow path according to the temperature of the intake air in a suction pipe between the throttle body and the engine. CONSTITUTION: A coolant supply method of a coolant flow path in a throttle body(100) comprises an electronic control unit(500), a suction pipe located between the throttle body and an engine(200), and a temperature sensor(300) which measures the air temperature within the suction pipe and supplies a sensor signal to the electronic control unit. The temperature of the suction air is measured based on the sensor signal, and an opening control signal opening a control valve(400), which closes a coolant flow path of the throttle body when the temperature of the suction air under a predetermined temperature is generated. The opening control signal is transferred to a driving motor of the control valve, and the coolant is supplied to the coolant flow path of the throttle body.
