Does the car fan run at idle?

[AbigailLee]

When the car is idling, the fan will start running after about 10 minutes. This depends on how quickly the water temperature rises. The time varies for different cars under different conditions. In summer, the time is shorter, while in winter, it takes longer. If the car is moving, the time will also be shorter. Here are some methods to determine if the car fan is working properly: 1. Listen for sounds in the engine compartment. When the fan is operating, it produces a whirring sound. Even near the engine, if you listen carefully in the engine compartment, you can hear the fan's noise. If the fan isn't running, you won't hear this sound. 2. Observe the fan's operation. Since the fan is usually installed at the very front of the engine compartment, it's in a position that's easy to observe. Simply check whether the car fan is spinning or feel with your hand if the fan is blowing air. 3. Monitor the water temperature. When the vehicle's water temperature reaches 80 degrees, the cooling system switches to a large cycle, and the fan starts running. Therefore, you can judge based on the water temperature gauge on the dashboard. If the fan doesn't start running after reaching the specified temperature, it's necessary to inspect the fan.
