Rislone Hy-per Cool Super Coolant by Hy-Per Lube is a high-performance cooling system additive formulated to maximize heat transfer in demanding driving conditions. For Indian car enthusiasts and owners of high-performance or heavy-duty vehicles, managing engine temperatures during intense summer heat or bumper-to-bumper traffic is crucial. This advanced formula utilizes synthetic wetting agents to significantly reduce the surface tension of your radiator fluid mixture. By lowering this surface tension, the coolant can more deeply penetrate critical metal surfaces inside the engine and radiator, drawing substantial heat away from hot cylinder heads. This advanced thermodynamic optimization can reduce operating engine temperatures by up to twenty-five to thirty degrees Fahrenheit, helping to safely advance ignition timing for increased horsepower while preventing destructive detonation. Beyond temperature control, this additive contains highly effective corrosion inhibitors that provide comprehensive protection against rust, electrolysis, and mineral scaling for all cooling system metals, including lightweight aluminum. It also lubricates water pump seals to prevent premature mechanical failure. Ideal for street cars, high-load towing vehicles, and racing applications alike, it features an ethylene glycol-free formula that is completely safe for tracks requiring straight water.

Ensure the engine is completely cool before removing the radiator cap. Shake the bottle thoroughly. Pour the entire sixteen ounce bottle directly into the radiator or the coolant overflow reservoir. One bottle efficiently treats cooling systems with a capacity of twelve to twenty quarts. For systems outside this range, adjust the dosage proportionally.

How to use rislone hy-per cool super coolant?

With a completely cooled engine, open the radiator or overflow reservoir cap. Shake the bottle well and pour the recommended dosage into the system. It can be used with straight water for racing or mixed with any standard antifreeze.

Is Rislone super coolant good?

It is an excellent preventive maintenance additive for high-performance, high-load, or older vehicles prone to running hot. The formula reliably minimizes overheating risks and safeguards system metals from electrolysis and corrosion damage.

Is this Rislone Super Coolant sold on Dropy India an authentic USA import?

Yes, all products on Dropy India are authentic USA imports. We source this high-performance coolant additive directly from trusted suppliers in the United States, ensuring Indian automotive enthusiasts receive genuine formulas.
