I have a 1938 Austin Big seven which came with a capillary tube type water temperature gauge which didn't work. I have now installed my Christmas present - a new capillary gauge and sensor and been out for a run. going along at about 35mph the temperature was 90 degrees C and as the outside temperature was around 4 degrees I became concerned as to what the temperature would be on a hot day in summer. 90 degrees is around the centre of the scale on the gauge but as water boils at 100c its not that far off - unless the boiling point is different when under pressure. Can anyone advise please?
