The ASTM, the organization that sets the bar in over 12,000 technical standards worldwide, has a waterless-coolant standard. With water added, it will behave just like regular coolant and lose the waterless-coolant benefits. You can add water or regular coolant to the system with no issues. If you have waterless coolant in your system and it is low and you didn’t bring extra waterless coolant to the track, don’t worry. It must be said that if there is residual water still in the system (over 3 to 5 percent), vapor pressure will build. There is moderate pressure build-up from a 7-percent fluid expansion, so if you open the radiator cap when the coolant is hot, it may spill out a few tablespoons, but it doesn’t have the vapor pressure that can blow up in your face like regular coolant. Waterless coolant doesn’t build vapor pressure in the system. Stable additives are added to the waterless coolant so the coolant never goes bad, whether it is used or still sitting in the container, so it never has to be replaced. Waterless coolant additives do not fall out of solution as with regular coolant. Instead of expanding when frozen, like water does, without the water, the coolant actually decreases in volume. The boiling point of waterless coolant is 375 degrees Fahrenheit and it freezes at -40 degrees Fahrenheit. They let us in on some secrets, good and bad, on the effects of waterless coolant. There are a few waterless coolant companies on the market, but only one markets worldwide and is highly involved in the motocross industry. Waterless coolant is made up of the same basic glycols as regular coolant but operates much differently without the water. Let’s state the obvious: waterless coolant is different from regular coolant because there is no water in it.
