Soon I will be due for a coolant change. So far I have used the original green coolant and have not had any cooling/overheating issues. Apart from leaking coolant due to a bad timing cover gasket I have not had any leaks whatsoever. Everything is still original (radiator, hoses) and so far holding up very well.

Each time when I am due for the change I am thinking if I should change to another coolant type (e.g. the 5 years formula) but I also read articles where they recommend to stay with the original stuff. I don't fancy to flush the complete system several times to fully remove the green stuff before putting in the "upgraded" orange (?) coolant.

So I am wondering, if the majority of G1/2 owners is still on the green coolant or has moved to the newer one? Let me know what you are using... ;-)
