What is the most common cause of engine overheating in a Kia Picanto?

I recently bought a used Kia Picanto and have noticed that it overheats very quickly. What could be causing this issue and how can I address it?

The most common cause of engine overheating in a Kia Picanto is a malfunctioning cooling fan. It could be due to a faulty fan motor or a blown fuse. Make sure to check these components first before exploring other possible causes.

Another possible cause could be low coolant levels. Check the coolant reservoir and if it's below the minimum level, top it off with a mixture of equal parts water and coolant. This should help regulate the engine temperature.

It could also be a problem with the thermostat. If it's stuck closed, it will prevent coolant from circulating properly and cause overheating. In this case, it's best to replace the thermostat with a new one.
