In fact, Evans says its coolant can reduce cooling system pressure to as little as two to four PSI. This repetitive cycling often leads to metal fatigue and component failure, especially with hoses, water pump seals, and radiator seams.īecause Evans Waterless Coolant has a boiling point above 375 degrees F, it will not vaporize and generate high pressure in the cooling system. When the engine cools down, the pressure goes down too.

Reduced Cooling System Pressure (Image/Evans Waterless Coolant)Īs water heats up and reaches its boiling point, it generates high vapor pressures that exert internal stress on cooling system components. This virtually eliminates the chances for electrolysis to occur. Since Evans Waterless Coolant has no water, its electrical conductivity is far lower than the typical 50/50 mix of ethylene glycol and water. Either way, electrolysis can cause corrosion, pitting, flaking, and pinholes in cooling system components. The coolant acts as an electrolyte, causing one metal to act as a cathode and the other as an anode. Another is the interaction of dissimilar metals in the cooling system. One source of those voltage differences is stray voltage from poorly grounded electrical components. Electrolysis occurs when electrical currents flow through the system due to voltage differences in the engine water jackets, the radiator, and the heater core. We’ve mentioned that water-based coolants can cause cooling system damage via electrolysis. Eliminating Electrolysis (Image/Evans Waterless Coolant) That means it will remain a liquid, maintain constant liquid-to-metal contact, and ensure consistent heat transfer. Boil-over during operation and after-boil when the engine is stoppedĮvans Waterless Coolant has a boiling point of over 375 degrees F, well above your engine’s operating temperature.Cavitation caused by vapor escaping due to pressure drops in the water pump.Reduced combustion efficiency and detonation issues in fuel-injected engines.Pre-ignition (engine knock) in carbureted engines.This overheating and excessive thermal stress leads to several problems: That makes the metal hotter still and the potential for overheating much greater. Vapor pockets insulate hot metal from liquid coolant and prevent proper heat transfer. At its boiling point, water-based coolant is not cool enough to condense the vapor, allowing vapor pockets to form, especially around the hottest parts of the cylinder head(s) where cooling is needed most. Vapor is about 94 percent less effective than liquid at conducting heat. At that temperature level, water-based coolant vaporizes into steam. Mixing traditional ethylene glycol antifreeze with water in a 50-50 ratio increases the boiling point to 223 degrees F, which is close to the operating temperature of an engine. *** Water Vapor, Killer of Engines (Image/Evans Waterless Coolant) Here are the major causes of cooling system failures and how Evans Waterless Coolant prevents them from happening. that are stored for extended periods of time. That makes it perfect for virtually any vehicle on the road, but is especially ideal for race cars and vehicles like classic cars, street rods, muscle cars, etc. Since it has no water, Evans Coolant is non-corrosive, stops electrolysis, prevents cavitation, and will last the life of the engine with no need for additives or regular coolant replacement. The resulting corrosion, cavitation, and electrolysis issues eventually reduce cooling system efficiency and shorten the life of radiators, water pumps, thermostats, seals, and gaskets.Įvans Waterless Coolant has a patented, glycol-based formula that provides excellent protection at high temperatures compared to traditional water-based coolants.

Water in the cooling system also degrades the metals in its components, usually from the inside out. Overheating is the most common cause of engine down-time and is responsible for over a third of catastrophic engine failures.

That can cause the coolant to vaporize at normal operating temperatures, leading to overheating and boil-over. Water has excellent heat transfer capabilities, but the typical 50/50 mix of coolant and water has a low boiling point, very close to most engines’ operating temperature. While these water-based coolants do a good job of keeping engine temperatures in check, they fall short when it comes to protection at high operating temperatures and over long periods of time. Since the 1930s, hot rodders and performance car enthusiasts have relied on engine coolants made from a mix of ethylene glycol, water, and corrosion inhibitors.
