Why is my Ford Mondeo making a strange noise when I turn on the engine?

I recently bought a Ford Mondeo and have been noticing a strange noise every time I turn on the engine. It sounds like a grinding or rattling noise and I'm not sure if it's something I should be concerned about. Does anyone have any advice on why this might be happening and if it needs to be fixed?

It's possible that your engine is low on oil, which can cause it to make strange noises. Check your oil levels and top up if necessary.

It could also be a problem with your spark plugs. Have a mechanic check them and replace them if needed.

I had a similar issue with my Ford Mondeo and it turned out to be a loose belt. Make sure all your belts are properly tightened.
