What is the most common issue with overheating in a Ford Focus?

I noticed my Ford Focus has been overheating more frequently lately. What could be causing this issue and how can I best address it?

The most common cause of overheating in a Ford Focus is a faulty radiator. I suggest checking the radiator for any leaks or cracks and replacing it if necessary.

Another possible cause could be a malfunctioning thermostat. I suggest having it checked and replaced if needed to keep your car running smoothly.
