Third, Evans Waterless coolant is hygroscopic, which means that it absorbs moisture from the air if not kept in a sealed container. If you leave more than 3 percent of the old antifreeze in the system, you will lose the corrosion-resistant properties of the Evans coolant. Second, to use a waterless glycol-based coolant, you must completely purge your engine of left-over antifreeze. First, if your engine’s water gets up to 375 degrees, there is something wrong with your system, although it is nice to have the failsafe of such a high boiling point. And, as you may remember from school, a pound of steam is made up of a pound of water. Steam also raises the pressure in the cooling system enough to blow open the radiator cap and start spewing the dreaded trail of white mist behind you.
When a pocket of steam forms, the coolant no longer wicks excessive heat away from that area. Steam forms at the hot spots of the engine (i.e., combustion chamber, cylinder liner and exhaust port), and keeping temperatures under control at these hot spots is crucial to engine performance. Steam has zero ability to transfer heat from the engine’s metal components.
Once it begins to boil, it turns to steam. Why would you want to raise your cooling system’s boiling point to 375 degrees? Because coolant only works as long as it stays in a liquid state. Still not enough? Evans Waterless Powersports coolant has a boiling point of 375 degrees Fahrenheit.
If that is not enough boil-over protection, you can replace the 1.1 kg/cm 2 radiator cap with a 1.8 kg/cm 2 (stock on Husqvarnas and KTMs) and up the ante to 278 degrees. Adding a conventional ethylene glycol and water antifreeze to the system raises the boiling point to 265 degrees. With the typical 1.1 kg/cm 2 radiator cap found on all Japanese-built motocross bikes, the boiling point of water is raised to 227 degrees. In a motorcycle’s radiator, for each pound you raise the system’s blow-off pressure, you raise the boiling point 3 degrees. WHAT STANDS OUT? Here’s a list of things that stand out with Evans Waterless Powersports coolant.
