Hi all, my E200(1994) water temperature has been acting up recently.Temperature used to range from 80-87 degrees C. But increased to 90-100 degrees C. After changing to a new radiator, temperature range is 79-93 degrees C. At times, temperatures could go up to 97 degrees C in stationary position. Is this within the correct oprating range? Could the thermostat be faulty? (I come from a tropical country:Singapore)Or issit the temperature sensor??
