WaterWetter® is a unique wetting agent for cooling systems which reduces coolant temperatures by as much as 30ºF. 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. Or it can 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.

• Doubles the wetting ability of water
• Improves heat transfer
• Reduces cylinder head temperatures
• May allow more spark advance for increased torque
• Reduces rust, corrosion and electrolysis of all metals
• Provides long term corrosion protection
• Cleans and lubricates water pump seals
• Prevents foaming
• Reduces cavitation corrosion
• Complexes with hard water to reduce scale.

RED300 - Red Line WaterWetter Supercoolant - $7.50
RED300C - Red Line WaterWetter Supercoolant - $81.00 per case of 12

Same improvements in cooling efficiency as WaterWetter®, but without the rust and corrosion inhibitors. Designed for heavy-duty diesel engines which use more than 33% antifreeze.

Its cooling system heat transfer agent for use with antifreeze / water solutions 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 cylinder head temperature by as much as 10-20°F. This product will not lower the temperature of the cooling system below the thermostat temperature and will be effective when the thermostat is wide open, such as heavy traffic of climbing long grades. This improvement in wetting helps reduce cavitation in liners and water pump..

RED309 - Red Line Diesel WaterWetter Supercoolant - $11.95
RED309C - Red Line Diesel WaterWetter Supercoolant - $129.06 per case of 12

SuperCool with WaterWetter® (80205) is a pre-mixed coolant for motorcycles, ATVs, karts, generators, and other small water-cooled engines. This product doubles the wetting ability of water to improve heat transfer and reduce cylinder head temperature.

Compatible with all glycol antifreeze and coolants, this product is blended with deionized and purified water and WaterWetter®, the most effective heat transfer agent available with corrosion inhibitors to satisfy the same ASTM corrosion tests which glycol-based antifreezes are designed to pass (ASTM D2570 and ASTM D1384). Red Line's WaterWetter® provides excellent rust and corrosion protection for modern cast iron, aluminum, and brass systems.

Use with a long-life antifreeze if freezing temperatures are to be encountered. This product does not contain anti-freeze and its freezing point is 32ºF or 0ºC. Available in 1/2-Gallon containers.
