What causes squeaking noise from the Ford Mondeo engine?

I recently purchased a Ford Mondeo and I've noticed a squeaking noise coming from the engine. It started a few weeks after I bought it and it's gotten louder over time. Any ideas of what could be causing it and how to fix it?

It could be a belt that needs to be replaced. Over time, belts can wear down and start to slip, causing a squeaking noise. I would suggest taking it to a mechanic to get it checked out.

I had a similar issue with my Ford Mondeo and it turned out to be a loose pulley. I tightened it and the squeaking noise went away. You can try checking all the pulleys and see if any of them are loose.
