Why is my Ford Galaxy experiencing engine overheat?

I recently bought a used Ford Galaxy and have been experiencing engine overheat issues. I've checked the coolant levels and they seem to be fine. What could be causing this and how can I fix it?

One possible reason for engine overheat could be a faulty thermostat. It's best to get it checked and replaced if necessary.

Check for any leaks in the cooling system and make sure all hoses and connections are secure.
