Water less coolant is not no coolant. In my youth, there was a time when antifreeze prices went crazy. I was a poor student with no money.
I had an old 6 cylinder 4x4 truck with a plow to clean my lane.
Instead of an antifreeze coolant, I used varsol. Smelled funny but was cheap. Probably very flammable at higher engine temps. I was young and stupid.
The Evans product is an expensive product to use when you don't have a severe cooling situation.
There are two common forms of antifreeze. Ethylene glycol and propylene glycol.
It is in the science that the properties of each arise in unexpected ways.
A property of a coolant is called specific heat. In simple terms, how many liters of coolant can transport a known quantity of heat (Btu').
A coolant with a high specific heat will require less flow to remove a fixed amount of waste heat from an engine.
A second property is viscosity. The higher the viscosity, the more horsepower required to pump the coolant.
In large engine situations, power generation for one example, the two factors have to be considered to end up with the lowest operating cost.
Lastly, propylene glycol is an edible product used as a sweetener in many foods we eat. If you could have a coolant leak where people could be present, having a spill of a non toxic coolant is a big relief.
Ethylene glycol is poisonous. Let your dog or cat drink some while you are replacing yours and you will, at least, have a very sick animal or a dead one.
