What is the most common issue with the Ford Fiesta coolant system?

I have been having trouble with my Ford Fiesta's coolant system, what could be causing it and how can I fix it?

It is possible that air bubbles have formed in your coolant system, causing it to overheat. You can try bleeding the system to release the air.

A leak in the coolant system could be another possible cause. Inspect for any visible leaks or low coolant levels.

Make sure to regularly flush and replace your coolant to prevent buildup and potential issues.
