Why is the Ford Fiesta Engine Making a Rattling Noise?

I have noticed a rattling noise coming from my Ford Fiesta's engine recently. What could be causing this and how can I fix it?

This could be due to a loose heat shield or a failing exhaust manifold gasket. To fix it, you will need to have a mechanic tighten the heat shield or replace the gasket.

It's possible that the noise is coming from a loose or worn out accessory belt. Have a mechanic check and adjust the tension or replace the belt if necessary.

Another potential cause for the engine rattling noise could be low engine oil. Make sure to check your oil levels and top up if needed.
