Why does my Ford Fiesta's engine sound strange?

I recently noticed that my Ford Fiesta's engine has started to make a strange noise. It's not too loud, but it's definitely noticeable. What could be causing this and how can I fix it?

It's possible that your engine might be low on oil, resulting in the strange noise. Check the oil levels and top up if necessary. If the noise persists, it's best to take it to a mechanic for further inspection.

Another potential cause could be a worn out serpentine belt or tensioner. These parts are important for keeping your engine running smoothly. If they're worn out, they can start making strange noises. Have them checked and replaced if needed.

Sometimes, a strange noise from the engine could be a sign of a more serious issue. It's best to get your car checked by a professional to diagnose and fix the problem before it gets worse.
