Interesting! I haven't specifically checked for corrosion yet, just looked for obvious breaks. Where exactly was the corrosion on your Corsa, and was it easy to spot once you knew where to look?

On the Corsa, it was right at the connector where the wiring harness plugged into the fan motor. It was kind of hidden under a rubber boot, so I didn't see it at first glance. Honestly, unless you're comfortable with electrical work, I'd suggest having a workshop take a look. Could save you a lot of time and potential headaches.

Thanks for the tip! I took it to a local shop, and you were spot on - it was a faulty connection to the fan. They cleaned it up and charged me 95€. Runs like a charm now, temperature is stable. Appreciate the help!

Sounds frustrating! I had a similar overheating issue with my old Opel Corsa a few years back. The symptoms were identical. Turns out, the cable connection to the radiator fan motor was corroded. Have you checked the plug and wiring leading to the fan for any corrosion or damage?
