No-Rosion Industrial Grade Cooling System Flush

Hardness in water and inhibitors in antifreeze combine with tiny rust particles to form abrasive gels that cause overheating and premature water pump failure.

These coolant gels also adhere to the inner surfaces of cooling systems, particularly in heat exchange areas, and literally "bake on" to form scales and deposits that reduce heat transfer, and cause overheating. Corrosion thrives under these scales, because it is not possible for inhibited coolant to reach the metal surface under the scale. This causes eventual leaks and system failure. Additionally, glycol in antifreeze breaks down over time to form acids that reduce the pH of coolant, and cause corrosion.

No-Rosion Coolant Flush is a powerful Industrial Grade formula that helps remove antifreeze gels and rust particles. It neutralizes weak acids, and cleans/primes metal surfaces inside the cooling system for follow-up treatment with No-Rosion Cooling System Corrosion Inhibitor. It is safe and easy to use, and does NOT contain any strong acids that can actually remain in the system even after the flush is complete, and do more damage than good.





No-Rosion's exclusive formula has previously only been available for high-dollar, industrial applications. Developed and used for cleaning boiler and cooling tower equipment, No-Rosion now makes state-of-the-art, fully-inhibited flush technology available for your car or truck. It has been formulated to be::

100% SAFE FOR YOU, THE USER, as it won't cause irritation of eyes or skin,

100% SAFE FOR THE ENVIRONMENT, as it can be safely flushed to drain,

100% SAFE FOR YOUR COOLING SYSTEM, as it is fully-inhibited and does not contain any strong acids,

100% SAFE FOR ALL METALS, including aluminum, as it's pH is neutral,

100% SAFE FOR PAINT, as sometimes splashing occurs during the coolant flush process.

Tests show that flushing with No-Rosion Industrial Grade Cooling System Flush optimizes the performance of No-Rosion Cooling System Corrosion Inhibitor, allowing it to provide maximum corrosion protection, scale/deposit prevention, heat transfer optimization, and system cleanliness. This is particularly the case if you are beginning your No-Rosion coolant treatment program with a system that has previously been neglected, and is already heavily contaminated.

Not sure whether to use No-Rosion Flush or HyperKuhl SuperFlush? The answer is simple. If your cooling system is composed cast iron with a copper/brass radiator, then No-Rosion Flush is your product of choice!  On the other hand, if your cooling system contains is composed primarily of aluminum or lightweight alloy components, then HyperKuhl SuperFlush is your product of choice, due to the extra protection it provides for sensitive aluminum and alloy metals.

DIRECTIONS FOR USE: With engine off and cool, open radiator drain petcock and drain coolant into container for proper disposal. Close petcock, pour entire contents of No-Rosion Flush into radiator, and fill cooling system with water. Replace radiator cap, start engine, turn heat on high, and run for 10-15 minutes. Turn off engine, allow to cool, open radiator drain petcock and drain/flush the system thoroughly. Can be safely flushed to drain without any environmental concerns. Close petcock, refill cooling system with straight water. Replace radiator cap, start engine, and run again for 10-15 minutes. Turn off engine, allow to cool, drain/flush as before. Fill cooling system with mix of antifreeze and/or water coolant. Replace radiator cap. For best results, add No-Rosion Cooling System Corrosion Inhibitor after flushing the system, as the metal surfaces inside the system are now cleaned and primed for optimal corrosion protection performance.
