Keep your engine temperature down with Redline Water Wetter coolant additive. Redline Water Wetter is a unique wetting agent for cooling systems which reduces coolant temperatures by as much as 30 degrees Fahrenheit. 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.

Redline Water Wetter can also be added to new or used antifreeze to improve the heat transfer of ethylene and propylene glycol systems. Designed for modern aluminum cast iron copper brass and bronze systems.
