What causes the Ford Fiesta to overheat?

I've noticed that my Ford Fiesta has been overheating more frequently lately. What could be causing this issue and how can I fix it?

It could be a number of reasons, such as a faulty thermostat or a leak in the cooling system. It's best to take it to a mechanic to get it checked out.

Make sure to regularly check your coolant levels and have your radiator flushed at least every 30,000 miles. This can prevent potential issues with overheating.

If your Ford Fiesta is reaching high mileage, it may be time to replace the water pump as well. This can help improve the cooling system and prevent overheating.
