Why does my Ford Mondeo engine make a loud noise on start-up?

I've noticed that my Ford Mondeo's engine makes a loud, squealing noise when I start it up. It seems to go away after a few minutes of driving, but is this something I should be concerned about? Is there something I can do to fix it? Thanks!

It's likely that your serpentine belt is worn or loose. This can cause the loud noise you're hearing. I recommend getting it checked and replaced if necessary.

You may also want to check your alternator or water pump. If they're failing, they can also make a loud noise on start-up. It's best to have a mechanic take a look to properly diagnose the issue.
