Coolant level low and engine damage alarm at high speed

Hello all, I have a problem with my Fiat Talento. After about 30 minutes of highway driving at a speed of 120 km/h the alarm goes off for chance of engine damage and the cooling water light is on. After 30 seconds and lowering the speed to 115 km/h the alert disappears. The car has been to the Fiat garage several times. They have replaced the water pump, and later another water pump, because apparently there are two in the car. The thermostat has also been replaced. The problem seemed solved for two months, but yesterday the same message appeared again. Does anyone have an idea what could be going on? The garage doesn't seem to know either. Any suggestions are welcome!

Check if the radiator fan is functioning properly. It might not be engaging at higher speeds, causing the engine to overheat. Ensure the fan relay and wiring are in good condition. Let me know if this helps or if you need further assistance.

Thanks vr the response, that is a very good tip and sounds plausible. I will ask the garage to look into this.

Make sure they also check the radiator for any blockages or debris that might be restricting airflow, as this can also contribute to overheating issues. Keep us updated on the progress or if you have any more questions!
