Interesting that the web page I looked at that explains this product used a +8 to demonstrate how to covert from water to the waterless coolant.
Richard they do sell it in Australia, mainly on the east coast. The dealer listed in Perth looks a little dodgy. You also have to buy a prep fluid to get all the residual water out of your system after you have drained it.
I wond how it goes after using a good quality coolant and if the prep rep get that out as well
