I will be driving down a long hill and the stop light flashes and the engine temp goes from 80'degrees to red line in less than a second. But I open the bonnet and the engine is cold. I disconnect and connect the battery terminal put the ignition on and the temp is back to 80 degrees. All in less than 2 minutes. I've flushed the radiator and engine and it carried on doing it, I took the thermostat out and it still does it. Can anyone help? I have a Citroen Berlin go 1.4 petrol I don't know what year it is I just know what its in the m59 category.
