What are the reasons for the loud noise from the engine fan?

The reasons for the increased noise from the engine fan are: 1. Noise caused by acceleration, whether the noise is normal, if the entire vehicle sounds excessively loud, it indicates a problem; 2. Belt noise, usually manifested as squeaking or screeching, belt noise means the belt is worn or loose, when one of the pulleys where the belt is located starts to malfunction, belt noise will also occur, when the belt no longer moves smoothly along the pulley, it will produce noise when the car accelerates. Engine maintenance methods: 1. Use quality-qualified engine oil; 2. Use qualified coolant; 3. Regularly clean the water tank scale; 4. Regularly remove carbon deposits from the engine; 5. Replace the vehicle's air filter, oil filter, and fuel filter on time; 6. Check if the spark plugs are damaged.
I noticed the engine fan keeps making noise, which is likely caused by a few common issues. After prolonged use, the fan bearings may wear out and produce abnormal sounds, especially when lubrication is insufficient; or the fan blades could be obstructed by dust or debris, causing rattling noises during operation; insufficient coolant can also overload the fan, increasing its speed and noise level. These issues need to be addressed promptly to prevent engine overheating and major problems. Regular maintenance checks on these components will ensure the system runs smoothly, making the car much quieter.
