What it's for:
  • Cooling System
What it does:
  • Performance
  • Reduces Engine Temperature
  • Prevents Overheating
  • Provides Maximum Corrosion Protection
  • When using Rislone Hy-per Cool Super Coolant with straight water, do I have to worry about corrosion problems?

    No, Super Coolant is formulated for use with straight water and will provide maximum corrosion protection.

  • Is Rislone Hy-per Cool Super Coolant compatible with all types of antifreeze?

    Super Coolant is compatible 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. Because Super Coolant is water based, do not use with Evan’s waterless antifreeze.

  • 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°F. 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.

  • How much Rislone Hy-per Cool Super Coolant do I install?

    Use one 16-ounce bottle of Super Coolant, part number HPC100, to treat 12 to 20 quart systems. For larger and smaller systems add 1 ounce per quart (4 ounces per gallon) of capacity.

  • How do I use Rislone Hy-per Cool Super Coolant?

    Never remove radiator cap when engine is hot. With engine off and cool, remove radiator cap and add contents of bottle. Reinstall cap and drive vehicle normally.

  • What if I don’t have direct access to the radiator?

    If you do not have direct access to your radiator, Super Coolant can be installed in the overflow tank. It will take 4 to 5 heating and cooling cycles for product to fully enter the system using this method.

  • 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.

  • How often should I add Super Coolant to system?

    For best results and protection, we recommend treating the cooling system once per year, and every time changing coolant.

  • How much of a cooling system temperature drop can I expect when using Super Coolant?

    In systems running a 50/50 antifreeze water blend you can expect a 6 to 8 degree Fahrenheit cooling temperature reduction. If using straight water, you can get up to a 30° F reduction. Cooling system temperature minimum is controlled by the thermostat, so if the vehicle is already running at the minimum, you will not see any reduction below that. But when towing, under load, racing or working the cooling system harder, this is where the reduction will be shown.

  • Why is reduced cylinder head temperature (CHT) so beneficial?

    The hottest area of the cooling system, and the engine itself, is around the combustion chamber and exhaust port. The metal is extremely hot and coolant is so hot that it can boil and create air bubbles which insulate the coolant from the metal, causing even more heat. Super Coolant reduces the temperature in this area up to 75°F which allows the engine to run more efficiently, reduces potential spark knock, allows timing to be advanced, and creates more power and torque.

  • 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.

  • Do I need to flush cooling system before using?

    No, the cooling system does not need to be flushed before using. But if the system is dirty you will receive the maximum benefit of the product by completely cleaning the system first.

  • Can it be used with extended life coolants?

    Yes, Super Coolant works equally well with extended life coolants.

When you push your engine to the limit, high heat and mechanical stress become severe problems. An effective engine coolant additive helps more efficiently transfer heat to keep cylinder heads cool and reduce the likelihood of detonation, power loss and damage. When you’re in the market for a reliable way to eliminate overheating issues and extend the life of your engine, Hy-per Cool by Rislone Super Coolant is a race-proven, effective solution that’s applicable to any car and driving situation.
