Rislone Hy-per Cool™ Super Coolant contains New Technology wetting agents which lower the surface tension of the water/coolant mixture, allowing it to improve the heat transfer of your cooling system. This will make your car's system dissipate more heat more efficiently, reducing engine temperatures by up to 14°C helping to prevent overheating. Rislone Hy-per Cool Super Coolant lubricates and protects water pump seals and helps prevent corrosion of ALL metals commonly found in cooling systems, including Aluminium. It is compatible with ALL types and ALL colours of antifreeze coolant and can be used with straight water for maximum cooling performance and corrosion protection. It allows safe advancement of ignition timing resulting in more horsepower and prevents overheating in high performance and high load engines.

  • Contains No Glycol
  • Provides No Antifreeze Capability
  • Complete Protection from Rust, Corrosion, Electrolysis & Coolant Gelling

Dosage & Directions

Add 1 bottle to treat 11.5 to 19L systems. For larger or smaller systems, add 30ML/1L of capacity. You can add to overflow tank, but it will take 4 to 5 heating and cooling cycles for the product to fully enter the system. For best results re-treat once per year.


Never remove radiator cap if engine is hot.

Always check for freeze protection if needed.

Frequently Asked Questions

If I increase the percentage of water in the system can I get even better cooling when I use Rislone Hy-per Cool Super Coolant?
Yes, you can get improved cooling and lower temperatures by adding additional water to your system. Keep in mind that you will not maintain the same freeze protection when you increase the percentage of water in the system. But if you live in a warm climate area and you change the mix to around 35% Antifreeze and 65% water you will still receive freeze protection down to 0°C. For most racing applications it is beneficial, and many times required to run 100% water in the cooling system and this with Super Coolant gives you the best cooling heat transfer.

Can I use the Rislone Hy-per Cool Super Coolant in a Diesel Engine?
Yes, you can. It will provide the same temperature reduction performance and corrosion protection in a diesel engine as gasoline. Adjust dosage as needed for larger cooling system size.

What if my cooling system is already full?
Usually the easiest way is removing some fluid from the system by using a coolant tester or old turkey baster to suck some fluid out. You can also open the drain on the bottom of radiator to remove enough fluid to add Super Coolant.

What are some of the most common causes of overheating?
Scale & deposits in the cooling system from hard water, and glycol dropout from old antifreeze can build up on the interior surfaces, and even plug coolant passages. Even a small amount of scale 1/16th inch thick can reduce heat transfer by 40%. Other causes include performance vehicles with larger engines which don’t have a large enough cooling system, towing over the rating of the vehicle, and mechanical problems like a bad water pump impellor.

Can Rislone Hy-per Cool Super Coolant be used on the race track?
Yes, one of the number one uses for Super Coolant is in racing vehicles, including drag racing, oval track, off road, monster trucks and many other motorsports events. Many racing series and tracks require that no glycol is put into the cooling system because once that leaks on the track it becomes very slippery and dangerous. Super Coolant does not contain glycol.
