What causes the engine to overheat on a Kia Sportage?

I recently experienced my engine overheating while driving my Kia Sportage. What could be the possible causes for this issue?

One possible cause could be a leaking radiator. The leaking coolant can lead to insufficient cooling, resulting in the engine overheating. I would suggest getting the radiator checked and repaired if necessary.

Another cause could be a faulty thermostat. A malfunctioning thermostat can prevent proper circulation of coolant, leading to overheating. I would recommend replacing the thermostat to solve the issue.

Low coolant levels can also cause the engine to overheat. Check the coolant level and add more if necessary. However, keep in mind that low coolant levels could also be a symptom of a larger issue, so it's best to get it checked by a professional.
