HI Sorry for the delayed reply - back in Sydney - all good, I think I have had a small leak for a long time and just reached the point where the system was feeling a bit parched... Ended up putting in about 2 litres over a couple of days and since then it have noticed no drops or level changes but that the temp is running about 5 C lower than before - strange how cooling systems work when they have coolant in... Yes I did ship the car to Aus but it was shipped full of fluids just dry for petrol, so can't blame the shippers.... Can recommend the Great Ocean Road especially from Lorne to Apollo Bay - they clearly designed if for the Caterham, with pullover spots for slow vehicles that people actually used!!!! Had a fantastic trip - 3500km in a week, just 2 hours needing the half hood and mostly empty roads. Cheers Curly
