Red Line Water Wetter Super Coolant additive is a unique wetting agent which reduces coolant temperatures by as much as 20° F. This is a liquid coolant treatment product which is designed to be added to solutions of antifreeze and water to help improve the heat transfer properties of glycol-based antifreeze. This liquid product can be used to provide rust and corrosion protection in plain water for racing engines, which provides much better heat transfer properties than glycol-based antifreeze. Improves the ability of coolant to wet heat transfer surfaces by 50%.
- Reduces or eliminates bubbles that form on hot metal surfaces to reduce coolant temperatures by up to 20°
- Superior heat transfer properties compared to glycol-based antifreeze
- Compatible with new or used antifreeze (including DEX-COOL and long-life versions) to improve the heat transfer of ethylene and propylene glycol systems
- Improves heat transfer and reduces cylinder head temperature
- Designed for use with all modern aluminum, cast iron, copper, brass and bronze cooling systems
- Cleans and lubricates water pump seals
- Reduces cavitation and complexes with hard water to reduce scaling
- Does not lower cooling system below the thermostatically-controlled temperature
- 12 fl. oz. bottle treats 12-20 quarts
