What’s the Noise

Do you ever hear a humming noise coming from your car? It’s not the radio, and it’s not your imagination. In fact, that humming noise is most likely coming from your car’s engine. But why is my car’s engine humming?

Moving Parts

The answer has to do with the inner workings of your car’s engine. To put it simply, your car’s engine is a big machine made up of a lot of small moving parts. When those moving parts are working together smoothly, they produce a low humming noise. However, if any of those parts are worn out or not working correctly, they can produce a higher-pitched noise.

One common cause of a high-pitched noise coming from your car’s engine is a faulty alternator. The alternator is responsible for charging the battery, and if it’s not working properly, it can cause all sorts of problems—including a high-pitched noise. Another possibility is that your car’s serpentine belt is loose or worn out. The serpentine belt is responsible for running all of the accessories in your car, so if it’s not working properly, it can also cause a high-pitched noise.

If you’re hearing a humming noise coming from your car’s engine, the best thing to do is to take it to a mechanic and have them take a look. they’ll be able to diagnose the problem and let you know what needs to be done to fix it.
