- Noise: If you notice a grinding, squealing, or humming noise coming from the front of your car, especially when the engine is running, it could be a sign that the radiator fan bearings are worn out.
- Wobbly Fan: Check if the fan wobbles or has excessive play when you try to move it. Worn-out bearings can cause the fan to move abnormally.
- Vibration: If you feel vibrations in the steering wheel or the dashboard when the radiator fan is running, it could indicate a problem with the fan bearings.
- Overheating: In severe cases, worn-out fan bearings can affect the cooling system's efficiency, leading to overheating issues in your car.
