Lacetti overheating issue

I'm writing about a potential issue with my 2010 Chevrolet Lacetti diesel. It has 82226 km. The engine tends to overheat, and the check engine light comes on sometimes. I suspect the radiator fan may be defective, possibly a faulty speed sensor. Anyone else had this?

I have a Lacetti too. I had a similar problem a while back. Is the fan blade spinning freely? If not, something might be blocking the cooling system. Could also be a thermal switch failure. Is the temperature gauge reading high?

Thanks. The fan blade seems to rotate okay when I check it. But I don't know if the thermal switch is working right. And how do I test the speed sensor to see if it's good? Can you tell me more about what happened with yours and how you fixed it?

In my case, it seemed like something was wrong inside the fan assembly. It was complicated, and I didn't want to damage the engine, so I went to a technician. A diagnostic is needed.

Thanks, a professional diagnosis is the way to go. I'll book an appointment with a workshop to get it checked out. The repair cost 250€, for those wondering.
