Water Wetter from Red Line is designed to help control overheating and increase coolant system efficiency by doubling the wetting ability of water. It improves heat transfer from the engine to the coolant system reducing running temperatures by up to 20°. Effectively reduces engine temperatures by up to 20°CCompatible with anti-freezesSuitable for use in all cooling system containing aluminium, copper. brass and bronze metals.Provides protection against rust and corrosionOne bottle treats most car / light van cooling systemsWater Wetter breaks down surface tension in the coolant to greatly improve heat transfer, the advantage is that better thermal conductivity avoids the likelihood of hot spots and vapour bubble formation and therefore helps quicker engine warm up. Water Wetter super coolant eliminates foaming, reduces cavitation, corrosion and lubricates water pump seals.Powerful anti-corrosion agents are also a property of Water Wetter and this mixes with all anti-freezes and loweri
