What is the average temperature of water in a car radiator?

The average operating temperature of water in a car radiator is typically between 180°F and 200°F (82°C and 93°C). This temperature range is maintained to ensure efficient engine operation, prevent overheating, and minimize the risk of coolant boiling or engine damage. To regulate the temperature, most vehicles are equipped with a thermostat that opens and closes to control the flow of coolant through the radiator. The thermostat ensures that the coolant reaches the desired temperature before circulating through the engine, and it also helps to maintain a consistent engine temperature during operation.
