Rislone® Hy-per Cool™ Super Coolant contains very high cloud point surfactants designed to provide maximum wetting (coolant surface tension reduction) at normal and high cooling system operating temperatures. This supercharged coolant mixture eliminates bubbles, resulting in improved heat transfer to dissipate heat more efficiently in the entire cooling system. Real world and laboratory testing shows reduced engine temperatures by up to 30°F helping to prevent overheating. Super Coolant lubricates and protects the water pump, and helps prevent corrosion, erosion and electrolysis of all parts of the cooling system, including aluminum, plastics, rubber and more. Super Coolant works with all types and colors of glycol/water based coolants including yellow, orange, pink, red, purple, blue, green regular silicate & non-silicate and extended life antifreeze. It also works great in systems containing only water. Provides extra protection against higher engine temperatures. Up to 75°F lower cylinder head temperatures (CHT) enhance engine efficiency, proving better fuel economy, power and performance. Use in gasoline classic cars, hot rods, trucks, RV’s, motorcycles, automotive, heavy duty, diesel, powersports ATV, off road, racing, towing and most anything else with a cooling system. Racing approved and safe to use from drag strips to the oval track. Contains no glycol. Provides no antifreeze protection. Always check for freeze protection if needed.
