Universal Flex-a-Chill™ Radiator Coolant Additive (500166) by Flex-a-Lite®. 12 per Pack. Flex-a-Chill™ coolant additive is compatible with all types of antifreeze, and it provides 100-percent corrosion protection with straight water. It utilizes corrosion-inhibitor technology validated by ASTM testing, preventing scale and blockage inside the cooling system.
- Provides corrosion protection for aluminum
- Prevent scale and blockage
- Reduce engine temperature by up-to 20 F
- Extend the life of your cooling components
- Improve coolant contact with radiator fins
- 100-percent water soluble
- Race track surface approved
- Lower PH value so that it does not harm aluminum
Flex-a-Chill™ delivers cooling and protection that reduces the temperature of the cylinder heads without the need of additional coolant gels. With a lower PH level (8.5) than many competing products, Flex-a-Chill™ is designed specifically to protect your expensive aluminum engine parts and radiator from electrolysis that corrodes the parts from the inside out. The formula also contains organic compounds that will prevent contaminates such as calcium and magnesium from developing into scales that clog your cooling system. Flex-a-Chill™ is a “bubble buster” for the water in your cooling system, providing improved contact, and better contact means better heat transfer by as much as 20 degrees Fahrenheit. One 12-ounce bottle treats 12-16 quarts of coolant with a minimum of 20-percent antifreeze for street applications. Race applications should double the ratio.
Flex-a-lite is a third-generation business that has been in the automotive industry for over half a century. In 1962, Eddy Davis, who was an Army Air Corps pilot in England during the Second World War, set up Flex-a-lite with the original ‘flex fan’ concept. The company is currently based in Fife, Washington, and run by Lisa Chissus, Eddy’s granddaughter. Lisa is the one who invented the now patented Flex-a-fit radiator sidetank design that provides superior heat transfer. Though Flex-a-lite continues to look for innovative performance cooling solutions, one thing that hasn't changed since the company's foundation is that all products are still engineered and manufactured in the USA, with American hands.
