Corrosive Properties: Unbeatable protection against corrosion and electrolysis. Benefits: Improves combustion, maximizes HP, prevents boil-over. Antifreeze Properties: Protects below -40C. Evans Powersports waterless engine coolant, available in a half-gallon It has been used by race teams around the world for years to keep their They dont pull. Waterless Coolant for: MX bikes, trail bikes, enduro bikes, street bikes, quad bikes, ATVs, UTVs and snowmobiles. Less Toxic: Evans Waterless Coolants have low toxicity. Freeze Protection: Evans Waterless Coolants freeze below -40F. Increases BHP: Evans Waterless Coolants eliminate pre-ignition and detonation caused by overheating - thus improving combustion efficiency and delivering more power. Prep Fluid Evans Prep Fluid is a waterless cooling system flush engineered specifically to purge the cooling system of water-based antifreeze after draining and before installing. Prevents Corrosion: Evans Waterless Coolants contain no oxygen, effectively eliminating corrosion and pump cavitation. Evans Powersports waterless engine coolant, available in one gallon and a half-gallon bottle, is designed for motorcycles, ATVs, UTVs and other powersports equipment. Reduces Pressure: Evans Waterless Coolants generate very low vapor pressures reducing strain on engine cooling system components. Eliminates Overheating: Evans Waterless Coolants have a boiling point above 375F and will not vaporize, thus eliminating overheating, boil-over and after-boil. Stable formula, will last the life of the application. Will not boil over, freeze-burst, or corrode system. They don't pull over to let their engine cool down, and neither should you. Powersports Coolant has been used by factory race teams around the world for years to keep their engines safe, no matter what the conditions. So much so that we're thinking of putting on the oil line an optional thermostat Tecnam approves.Evans Waterless Powersports Coolant is a proprietary base fluid with a specially formulated inhibitor package designed for all liquid-cooled powersports applications. So much so that even in the summer we have to put some aluminum tape over part of either the oil radiator, coolant radiator, or both to get them to run up in optimum tempurature ranges for oil for decent part of the flight. I MIGHT be able to find out by calling the A&P guy who did that 3 years ago.Īs for the reported issue of the engines running hot because Evans doesn't have as high heat transfer capacity:Īll I can say is that in OUR case both Rotax engines I have (the old 80HP on a Skyranger, newer 100 on Tecnam), both under pretty tight cowls, (one with traditional coolant, one with Evans) both run very much on the COOL side, even when climbing with outdoor temps high. Good point about finding out if they're mixable from Evans(will go to Evans and try to find that out) because in the engine log the note on installing Evans doesn't say WHICH one is in there. Thanks for your, as usual, considered advice, Roger. Open air engines usually didn't have an issue, but tight cowl engines did. This put many up to and or over the max temp for the engine. 
Most have gotten away from Evans because it carries a 20F-30F temp penalty depending on the application. Will not build vapor pressure and is safe for pump seals and bearings. Unless the coolant in the system has a color you may not be able to tell which one is in there. Evans PS Coolant is ready-to-use and requires no mixing with water. This may be a better question about mixing either of the three directly with Evans unless it states something on their website. "Evans 1012PF Waterless Powersports Coolant" "1.Vintage Cool 180° is specially formulated for increased yellow metals and the more porous cast metal parts found in Vintage engines.Ģ.Classic Cool 180° is specially formulated for engines with more cast steel and iron, with reduced levels of copper and the introduction of aluminum products.ģ.Power Cool 180° is specially formulated for high performance engines."Īnyone know if the one for sale at Amazon is appropriate? approx $45 down to about $17.īUT I note that Evans makes three different formulations:
Looks like minimal quantity I can buy is half gallon, even though I don't expect to likely need more than a cupful, if that, ever.įound quite a price range for half a gallon. (I know adding more than a tiny trace of water to Evans is a general no-no,Īnd AFAIK shouldn't add other coolants to it.) I know that Rotax isn't pushing Evans as hard as it once was, and that the other coolants are fine, but since it's in there already figure I'd keep it.īut want to have a little extra around in case I ever need to top it up. Unlike our older 912UL this one had Evans coolant put in it a couple of years ago.
