Waterless coolant

[HaventgotaClio]

Has anyone used the water wetter pictured earlier in the post?

Yes, use this exact stuff in my very highly strung 998cc Mini7. I wouldn't bother in anything other than a track/race car though where you are really pushing for that last little bit of cooling. It reduces temps about 2 degrees in my engine.

So this Evans is nothing more than typical undiluted glycol?? I had no idea. If that is the case, then you are being sold. I go through hundreds of liters of the stuff each year and I can assure you that it does not reduce corrosion to any great deal when placed next to other inhibitors/frost/boil protection additives. Against water on its own it is a million times better obviously though. I'm glad you touched on how gloopy it is. Even when diluted with water at about 75-90degC it is noticably less free flowing than a normal water solution.

Hey its about time the forum has a good debate lol.

Evans won't disclose the formula but describe it as a low viscosity synthetic liquid. Wikipedia describes waterless coolant as "a glycol-based liquid substance that does not contain water"

Also.... https://www.norosion.com/evanstest.htm
"Evans offers several different iterations of their waterless coolant products. Each is 100% glycol. Some are 100% propylene glycol, and others are a mix of propylene glycol and ethylene glycol."

I have waterless coolant in three of my cars (not including the Vee). Other than a high initial cost, I have had no issues with it and find that the two cars in which I replaced water / antifreeze mix, the engines run slightly cooler on the gauges. I built the third car (a Westfield Eleven) and filled it with waterless coolant from new so have no comparison with the A series engine.

Having once had a cooling fan issue that saw the Sunbeam Lotus sneak up over 100 degrees (I was reversing half a mile down a twisty single track lane because a lady in a Peugeot 306 was incapable of reversing 30 yards back to a gateway) I was particularly tempted by the high boiling point of the waterless coolant meaning such an episode in the future would not see pressures rise and leave me worrying for my head gasket!

Pure glycol, highly toxic and also flammable as it is an alcohol, safer when diluted with water as per standard coolants (which are also based on ethylene glycol, same shit!) good quality antifreeze contains corrosion inhibitors so that knocks that argument out of the water unless you buy absolute cheap shite based on methylene glycol where you get what you paid for. Glycol is not a lubricant so your water pump would not last any longer. Caveat emptor and ‘a fool and his money are soon parted’ spring to mind, if you want to waste money I will send you my address and can supply loads of TEG for £150 a fill, about 50x it’s market value :rofl: :rofl: :rofl:
Ps I wouldn’t put it in my car
