What causes the engine to overheat in a Kia Rio?

I have been experiencing frequent overheating in my Kia Rio. What could be the cause of this?

The most common cause of overheating in a Kia Rio is a malfunctioning thermostat. It is recommended to have it checked and replaced if necessary.

Low coolant levels can also lead to overheating. Make sure to regularly check and refill your coolant.

A failing water pump can also cause overheating in a Kia Rio. It is important to have it inspected and replaced if needed.
