Specifications: ASTM D2570 and ASTM D1384 Color: Pink Concentrate: Treats 3 to 5 gallons or 13.2 to 15.9 liters. Volume: Case of 12 - 12oz Bottles Redline Water Wetter include a unique agent that lowers temperatures by reducing or eliminating bubbles or vapor barrier that form on hot metal surfaces Product Features:Unique agent for cooling systems that doubles the wetting ability of water that can reduce temps by 20 degrees F.Rust and corrosion protection allows for use of straight water in racing or reduced antifreeze levels in warm climatesImproves heat transfer and reduces cylinder head temperatureMay allow more spark advance for increase power and efficiencyUse one bottle for most passenger cars and light trucks, treats 3 to 5 gallons or 13.2 to 15.9 liters. Vehicles with larger cooling systems should use two bottles. Small cooling systems should use 1oz (3 to 4 capfuls) per quartCompatible with new or used antifreeze (including DEX-COOLTM and long-life versions) to improve the heat transfer of ethylene and propylene glycol systemsSatisfies ASTM D2570 and ASTM D1384 corrosion tests for glycol-based antifreezes RED LINE WATERWETTER COOLANT ADDITIVESReduces or eliminates bubbles or vapor barrier that form on hot metal surfaces to reduce coolant temperatures by up to 20Superior heat transfer properties compared to glycol-based antifreezeCompatible with new or used antifreeze (including DEX-COOL and long-life versions) to improve the heat transfer of ethylene and propylene glycol systemsImproves heat transfer and reduces cylinder head temperatureDesigned for use with all modern aluminum, cast iron, copper, brass and bronze cooling systemsCleans and lubricates water pump sealsReduces cavitation and complexes with hard water to reduce scalingDoes not lower cooling system below the thermostatically-controlled temperature
