Came accross info for heavy equipment about waterless antifreeze in offroad heavy equipment & 18 wheel type trucks.
Has anyone here tried any of this type antifreeze or have any info on it?
"Evans" is the name in the USA available. Around $40 or so a gallon.
Do not add water, unless emergency.
I am always concerned of corriosion in my cooling systems, caused by the water of typical 50/50 antifreeze.

Galvanic corrosion is a part of every system in the world. dissimilar metals in the prescience of a electrolyte will erode the anode. we have iron blocks and alloy water pumps. So unless this coolant is NOT and electrolyte it will not help with corrosion, only with boiling point and environmental stuff.

edit: I just watched the video and it says nothing about galvanic corrosion, only about reducing pressure to reduce corrosion

Got John Deere version in my XJ and 4 wheeler...

I will read up on the John Deere type, thanks,
and will check on Amzoil type also.
Evans seems to be a 2/3 ethylene glycol, and I believe 1/3 propylene glycol, no water.
Our everyday antifreeze is ethylene glycol based, and 50% water.
I believe water is the weak point when it comes to corrosion....

I keep my vehicles many years, and keep them well maintained, so
always looking for better products.
I have my cycle since 1989, my 38 Plymouth since 1986, and my
Chevy Van since 1979.

Water Is very important in an xj, normal operating temperate will boil straight antifreeze. Chemicals usually have a lower boiling point than water.

Water does cause corrosion but it keeps it from boiling. As long as its 50% mix you shouldnt corrode.

He's not talking about straight antifreeze. Its a coolant made that is ready to pour, no mixing with water. Thats just the way its made. Convenient and works great? Awesome.

Chemical have a higher boiling point than water.
Evans coolant has a boiling point of 370 degree,,,,no water added.

Normal coolant used today, ethylene glycol, has a boiling boiling point of around 370. When we add water to 50/50 mix, the boiling point drops
to around 220 with no pressure, and the boiling point goes up when the pressure goes up.

Straight water is the best coolant, antifreeze is there to prevent freezing and corrosion.
Snake oil!

Really my Prestone bottle disagrees

Prestone comes with new owner/manufactures every couple of years, from FRAM, Union Carbide, Glad, Vestar Capital Partners, Allied Signal, Honeywell, to Rank Group in 2011.
It is one of many typical 50/50 mixes of ethylene glycol/water.

This is basically true, except for the Snake oil, that if you are not having abnormal problems, that other than freezing, water if fine.

I have run my cars many years like this.
Water all summer and flush often, until cold weather, 50/50 mix.

But if there is something better, I am all for it.
