What can cause my Kia Rio's engine to overheat?

I've been experiencing issues with my Kia Rio's engine overheating, what could be the cause of this?

It could be a problem with your radiator, make sure to check for any cracks or leaks. You may also need to flush and refill your coolant.

Your thermostat may be malfunctioning, causing your engine to overheat. Have it checked and replaced if necessary.

Make sure your radiator fan is functioning properly, as it helps cool down the engine. If it's not working, it may need to be replaced.
