In the Cooling System, which component operates the cooling fan based on temperature readings?

• A. Radiator
• B. Water Pump
• C. Temperature Sensor and Thermometer
• D. Drain Valve

Answer: (C)

The cooling fan is driven by a temperature-sensing device that monitors coolant temperature and signals the fan to turn on when needed. The temperature sensor (often paired with a thermometer reading) provides the temperature data to the fan control system, which activates the fan to pull air through the radiator and cool the coolant. The radiator itself is just the heat exchanger, the water pump circulates the coolant, and the drain valve is only for servicing. Since only the temperature-sensing component reads the temperature and triggers the fan, it is the correct choice.
