How to Solve the Problem of Abnormal Noise from Car Fan?
2 Answers
Car fan abnormal noise solutions are: 1. Repair the air conditioning fault machine and air conditioning belt; 2. Clear the air conditioning pipeline; 3. Repair the electromagnetic clutch. The car fan is controlled by the engine coolant temperature switch, which is divided into silicone oil clutch cooling fan and electromagnetic clutch cooling fan. Classification of car fans: 1. Axial flow fan, the blades push air to flow in the same direction as the axis; 2. Centrifugal fan, the blades push air to flow in a direction perpendicular to the axis; 3. Mixed flow fan, the air intake is along the axis, and the air outlet is along the diagonal direction of the axis and vertical axis; 4. Cross-flow fan, which produces a large area of airflow, and both air intake and outlet are perpendicular to the axis.
Last time my car's fan was making strange noises. At first, I thought it was a minor issue, but later realized it might be the fan blades hitting something, like a small stone or leaf stuck in it, especially during rainy days when this happens more easily. I first checked it myself by opening the hood and carefully cleaning the area around the fan, making sure the blades weren't bent or broken. For older cars, you should also check if the fan motor bearings are worn out—if they make squeaking sounds, you might need to add some lubricant or replace them. A loose fan belt can also cause noise; just use a wrench to gently adjust the tension. It's best to clean the fan regularly, as accumulated dust can make the noise worse. If the strange noises persist, don't ignore it—driving in summer can easily lead to overheating, and a burst radiator would be a big problem. Get a professional mechanic to check it out promptly to ensure safe and worry-free driving.
