Why does my Kia Sportage's engine overheat?

I recently noticed that my Kia Sportage's engine has been overheating more frequently. It seems to be happening during longer trips or when driving uphill. What could be causing this issue and what steps should I take to fix it?

It's possible that there could be a problem with your car's cooling system. It's important to check the coolant levels and make sure there are no leaks.

Another possible cause could be a faulty thermostat. This could be preventing the coolant from properly circulating and causing the engine to overheat.

If you've recently changed your oil, it's important to make sure the correct type and amount was used. Incorrect oil levels or type can lead to engine overheating.
