Why is my Ford Puma's engine overheating?

I recently bought a used Ford Puma and noticed that the engine tends to overheat after driving for a while. I've checked the coolant levels and they seem fine. What could be causing this issue and how can I fix it?

It could be a problem with your radiator or cooling system. Have a mechanic take a look at it to diagnose the issue.

I had a similar issue with my Ford Puma and it turned out to be a faulty thermostat. Get it replaced as soon as possible to prevent further damage.
