If you look at MSDS of evans coolant
, it is ethylene glycol + propylene glycol + corrosion inhibitors. Nothing special at all about it. Other then the fact it will have ~1/3 heat capacity of water and 1/3 thermal conductance of water, and will have about 1/3 flow from thick viscosity of propylene glycol, and result in huge increase in core temps. Just 50% propylene glycol + water caused 8C worse core temps in skinneelabs testing. Now imagine no water at all, just all propylene gycol and eythylene glycol, so will increase core temps by significantly more than 8C.
In our pumps, there is no boiling and no cavitation, so no use at all for glycols. If you want anticorrosion, just get concentrated inhibitors without the glycol.
No intelligent reason to put 68% glycol, 30% propylene glycol, 2% inhibitors in one's car....let alone in a computer loop where the boiling/freezing temps are completely irrelevant. The only difference in a water loop you will see is MUCH higher core temps from combination of very poor thermal properties and much reduced flow from the thick viscosity of the glycol mix.
marketing hype aside, if the stuff was so great, all car manufactures would eliminate water and run same. You can buy all the ingredients for a few bucks at any chemical plant.
