I totally agree with Barrie, just use standard ethelene glycol based antifreeze, The Blue Stuff.

Ethylene Glycol is however toxic, that’s why you do not add it to wine as a sweetener — or let your dog drink it — but it has been proudly strutting its stuff since 1926, works and is cheap.

Propylene glycol is regarded as less toxic and therefore used in Switzerland.

Specialized coolants (Toyota et al), were developed for high temperature and high pressure applications, not really the average Scott scenario.

Regarding Evans Coolant, which has amazing claims made about it, is a neat mixture of glycols – no water, very expensive and is flammable, I looked into this some time ago for a special engine I was building, and rejected it.
