5 litres of Evans Waterless Coolant will set you back around $120.00. And for a Sigma you will need two packs.
And a cleanout of the system prior to adding the coolant is another $ 72.00 for 5 litres. So I should imagine that will require two packs as well.
There is an Australian produced alternative from Liquid Intelligence ..that costs a whooping $166.50 for 5 litres.
It is a brilliant idea..no water = no corrosion..ever. And the boiling point is almost twice that of water. And it does not expand..so no more pressure issues when the old girl starts running a bit hot.
