Took them 2 days cause I wanted them to make sure there was no old coolant so flushed things out with water many times etc.. It was painful handing the keys to another man even if he is a good friend.
So far the Evans is doing more then fine. I didn't switch over to a low pressure rad cap yet. But will know more after the first track day of the season. Spec wise I think it's a good idea to prevent me from blowing gaskets etc...

Thanks for the response. I am now convinced this will be the way I will go once my Elise is out of warranty. For me the one time fill and the lack of corrosion and pressure with the waterless Evan's are the main reasons I want to do it. The poor reputation of the Havoline DexCool as supplied by Lotus is the other reason I want to do the conversion. Knowing the conversion will be a major PITA I will just plan to do it during the winter here when I am not using the car.
