Are you wondering at what temperature the radiator fan in your car turns on? The radiator fan plays a crucial role in preventing the engine from overheating. When the coolant temperature rises to a certain level, the fan kicks in to cool down the radiator and prevent any damage to the engine.
So, let’s dive into the details and find out the temperature at which the radiator fan turns on:
Temperature in Celsius:
The exact temperature at which the radiator fan turns on may vary depending on the make and model of your vehicle. However, in most cases, the fan typically kicks in when the coolant temperature reaches around 95°C.

Temperature in Fahrenheit:
If you prefer Fahrenheit, the radiator fan usually engages when the coolant temperature reaches approximately 203°F. Once again, please note that these temperatures can vary slightly depending on the specific vehicle.
Factors Influencing Fan Activation:
While the temperature ranges mentioned above are general guidelines, it’s important to understand that there are other factors that can impact when the fan turns on. These factors can include the type of engine, ambient temperature, and the specific cooling system design.

How Long Does It Take for the Radiator Fan to Turn On?
The time it takes for the radiator fan to turn on can vary, but normally it should activate within a few minutes of the engine running. Once the engine reaches the threshold temperature, the fan will engage to prevent any further increase in coolant temperature.
Should the Radiator Fan Come on When the Car Starts?
No, the radiator fan should not come on immediately when the car starts. The fan is designed to only engage when the engine temperature rises above the set threshold. Therefore, it is normal for the fan to remain dormant during the initial start-up of the vehicle.
How Long Should the Radiator Fan Stay On?
Once the radiator fan turns on, it will continue running until the engine cools down and the temperature falls below the threshold. This ensures that the engine stays at an optimal operating temperature.
What to Do If the Radiator Fan Doesn’t Turn On?
If you notice that your radiator fan isn’t turning on, it could indicate a problem with the fan motor, fuse, relay, or a wiring issue. It is recommended to consult a qualified mechanic who can diagnose and fix the issue to avoid any potential engine damage.
In conclusion, the temperature at which the radiator fan turns on varies depending on the vehicle. However, a general guideline is around 95°C (203°F). If you have any concerns about your radiator fan not functioning properly, it is always best to consult a professional mechanic for a thorough inspection and appropriate repairs.
Frequently Asked Questions Of What Temp Does Radiator Fan Turn On
How Long Does A Radiator Fan Take To Turn On?
The radiator fan typically takes around 5 to 20 minutes to turn on after the car has reached its operating temperature or when the coolant temperature exceeds a certain threshold.
Should Radiator Fan Turn On When Ac Is On?
Yes, the radiator fan should turn on when the AC is on. If the fan doesn’t run, it could indicate low refrigerant levels, a faulty switch or sensor, a bad fan motor, fuse, relay, or wiring problem. The Engine Control Unit (ECU) typically controls the fan based on the coolant temperature sensor.
Failure to turn on the fan when needed can lead to engine overheating.
What Tells The Radiator Fan To Turn On?
The radiator fan is activated by the Engine Control Unit (ECU) in most modern cars. It receives a signal from the coolant temperature sensor, which determines when the fan needs to turn on. If the ECU or the coolant temperature sensor is not working properly, the fan may not turn on when it should, leading to potential engine overheating.
When Should Electric Cooling Fans Come On?
The electric cooling fans should come on when the engine reaches a certain temperature. The fans are controlled by the Engine Control Unit (ECU) which receives signals from the coolant temperature sensor. If the temperature rises beyond the normal range, the ECU will activate the fans to help cool down the engine and prevent overheating.
It’s important to ensure that the fans are functioning properly to maintain optimal engine performance.
What Temperature Does The Radiator Fan Turn On At?
The radiator fan typically turns on when the engine coolant reaches around 200°F (93°C) to prevent overheating.
