Why does my engine coolant light come on when I tow my caravan?
I own a 2012 Ford Mondeo 2.0. When towing my caravan the engine coolant light came on with loss of power, after a minute or so the power returned and the light went off. After pulling into the caravan site, I checked the coolant, which was to the max line. This has happened twice. Any ideas?

Obviously the engine runs hotter when towing because there is more load on it and less speed so less airflow through the radiator. The engine temp sensor/sender switch that switches on the electric fan should cope with this, but I think yours is a little lazy and temporarily caused the engine to overheat, hence the lack of power.
