Red Line Cooling System Water Wetter improves the ability of coolant to wet heat transfer surfaces by 50%. This provides significantly better coolant contact in the cylinder head and can reduce coolant and head temperature by as much as 20° Fahrenheit. Can be used with 100% water in racing but does not protect magnesium from corrosion or alter the freezing point significantly. Use one ounce per quart or one bottle in a cooling system of 12-20 quarts capacity.
Red Line Water Wetter passes the ASTM D2570 Simulated Service Corrosion Test (the most severe test developed for automotive coolants) with a significant margin to spare. This test circulates coolant for 1094 hours at 190°F through a simulated engine block with test samples of metals commonly found in automotive cooling systems. The weight lost due to corrosion is then calculated for each sample. An independent test lab showed that a 3.1% volume concentration of Water Wetter in tap water (not distilled water) protected copper, brass, steel, cast iron, cast aluminum, and 30a solder -- better than the test requirements, and better than the competition!
