Ever since we have had our i10 Style I have wondered why the temerature gauge only ever seems to show a maximum temperature of about 75-80 degrees. I have always understood that modern engines run at around 102 degrees with the radiator being pressurised to achieve this above boiling point temperature. Am I wrong in this assumption? If not this begs the question either the gauge or sensor is faulty or the thermostat is not closing properly, allowing the engine never to achieve it's correct working temperature. This may go some way to explaining the mpg figures being somewhat less than they probably could be! Anyone any advice to offer on this one?
