The temp gauge is just at the middle sitting right on the wavey lines on the temp sign when at 80c (so just below dead upright). The thermostat would open at above 50c if i put my foot down a few times, otherwise with normal driving it would open about 80c (by checking if bottom rad hose was warm). By inserting the renault 5 thermostat in the top hose, the bottom hose will now only get warm at approx 84c no matter how much i put my foot down, so that led me to thing the original thermostat had a lazy spring and the water pressure from accelerating was pushing past the thermostats seal and allowing coolant to flow through the radiator...
