Not been on here for an awfully long time, so hello again.
Does anyone have any experience of using waterless coolant? Waterless coolant is propylene glycol as far as I know. It has a much higher boiling point than water, but it's specific heat capacity is far lower than water, which means that it is less efficient at transporting waste heat from your engine to your radiator, which means that your engine will potentially run considerably hotter than it's design temp when running waterless coolant, but it won't boil. I'm somewhat nervous about using waterless coolant.
