They say you donít need to worry about boiling. I guess it just dosnít boil at any thinkable temperature. I would be tempted to run it w a 230 (or so) degree thermostat .. if available. Never heard of such a thermostat. Should/may eliminate the underloading issue by keeping the lube oil quite warm. May be good for all or most engines. Should burn less fuel.
Also may not be able to do this w/o running higher system pressures that may/would require special hoses that could deal w the higher pressures and temps. Blow head gaskets???

I believe you are referring to "waterless" coolant. If so this is the most popular brand https://www.evanscoolant.com/
I own a classic car and if you want to ignite an online firestorm mention this in one of those forums, it's controversial to say the least. I don't use it.
If your cooling system is in good condition, and you replace the coolant every two years (or at the very least have it analyzed), the elevated boiling point established by conventional coolant, and a pressurized cooling system (that pressure raises the boiling point three degrees for every pound of pressure, as well as decreasing cavitation erosion) provide all the cooling and corrosion and boil protection you need. Some engine manufacturers recommend the periodic addition of a coolant supplement that further decreases cavitation (my International 7.3l Ford diesel calls for this) erosion, particularity for wet liner engines. Part of your cooling system service should include regular inspections of the pressure cap, remove it when cold and inspect the rubber gaskets, there should be two for systems that use a recovery bottle, as well as the check valve.

On the subject of cooling systems, here's a brief column on he subject of coolant recovery bottles, how they work and their importance as a troubleshooting tool https://stevedmarineconsulting.com/t...overy-bottles/
Where coolant is concerned, I strongly recommend using the latest recommendation from the engine manufacturer. Today there are a wide range of coolant types, using the wrong one can create costly issues.
