Red Line 80205 SuperCool® Extreme Ready-To-Use Coolant with WaterWetter® - 1.89L
Ready-to-use Red Line cooling-system fluid for motorcycles, ATVs, karts and other suitable powersports cooling systems where a pre-mixed high-performance coolant is required.
SuperCool® Extreme, formerly known as SuperCool® with WaterWetter®, combines purified deionised water with the correct concentration of Red Line WaterWetter technology to provide a convenient pour-and-go cooling-system fluid.
Red Line states that the formulation helps reduce or eliminate bubbles and vapour barriers forming on hot metal surfaces, improving heat transfer and potentially reducing coolant temperatures by up to approximately 20°F / 11°C under suitable operating conditions.
SuperCool® Extreme also helps reduce rust, corrosion, electrolysis and cavitation, cleans and lubricates water-pump seals, and helps reduce scaling caused by hard water. It is compatible with modern aluminium, cast iron, copper, brass and bronze cooling systems.

Fitment advice: SuperCool® Extreme is application-based rather than vehicle-specific. It is primarily intended as a ready-to-use cooling fluid for motorcycles, ATVs, karts and similar powersports applications with compatible cooling-system materials.
Other items to consider: When servicing the cooling system, you may also want to consider replacement radiator caps, hoses, hose clips, thermostats, water pumps and other related cooling-system service components where required.
Useful tools / consumables: Drain pan, filling funnel, protective gloves, workshop towels and suitable cooling-system bleeding equipment where required.
Difficulty guide: DIY Difficulty: Easy to Moderate. The fluid itself is ready to use, but draining, refilling and correctly bleeding a complete cooling system requires suitable tools and care.
Why Red Line? Red Line Synthetic Oil is known for high-performance lubricants, fluids and additives developed for demanding road, track and motorsport use.
