ADVANTAGES OF EVANS POWERSPORTS
The Benefits of Evans Powersports Coolant
Evans Powersports Coolant is an innovative solution for motorcyclists involved in enduro and motocross, where extreme conditions place significant stress on engine cooling systems. From mud-clogged radiators during motocross races to intense clutch demands in enduro hill climbs, our engines face tough conditions, and any overheating can lead to major issues.
Evans Waterless Coolant was developed to eliminate these concerns, offering an exceptionally high boiling point along with anti-freeze and anti-corrosion properties. The team at Enduro21.com sought to learn more about this product and reached out to John Light, the Director of Evans’ Powersports Division, to better understand the coolant's advantages and how it works.
Why is a High Boiling Point Important?
John Light explains:
"The boiling point of coolant is a critical factor for engine safety. Typically, when we talk about engine temperature, we’re referring to the coolant temperature. If the coolant temperature is between 90–100°C (194–212°F), everything is fine, but if it exceeds 110°C (230°F), major problems can occur, such as steam and pressure loss, which lead to reduced engine performance."
"While engine metal can tolerate a temperature increase of 10°C (50°F), when coolant boils and forms steam, it can no longer efficiently cool the engine. Steam displaces the coolant from the metal surfaces, causing the metal's temperature to rise rapidly, potentially resulting in detonation. Evans Coolant remains in a liquid state even at high temperatures, allowing the metal to dissipate heat efficiently and maintain optimal engine temperatures."
What Happens When Engine Temperature Rises Too Much?
"When engine temperatures get too high, the cylinder head can start to warp. Warping occurs due to uneven pressure caused by inconsistent temperature increases across different parts of the engine. When this happens, the head gasket fails. In a motocross or enduro engine, boiling typically starts on the exhaust side of the cylinder head because this is where the highest temperatures occur. This phenomenon can lead to engine damage, but Evans Coolant helps manage these temperatures, keeping them under control and preventing such damage."
Evans Powersports in Top-Level Racing
"Evans Powersports Coolant is used by many top teams and riders in both motocross and enduro. In the past, many of them used Evans Coolant secretly, fearing they would reveal their 'secret advantage.' For example, in GNCC competitions, which feature long races through muddy tracks, Evans Coolant remains effective even when radiators are clogged, protecting the engine. Evans Coolant is utilized by teams like Honda Racing, Yamaha Factory Racing, RedMoto Enduro, Beta Factory, and many others."
What If Water or Old Coolant Remains in the System?
"Evans Powersports Coolant is a special blend that contains no water. If excess water is added, it will act like a water-based antifreeze, thus compromising the benefits it offers. However, in emergencies, water can be added to get home safely. Evans recommends keeping water content below 5% for optimal performance. As for the process of replacing coolant, this can involve using Evans Prep Fluid to clean the system. For motocross bikes, however, a smaller amount of flushing fluid can suffice."
Evans Powersports Coolant is a game-changer for motorcycle enthusiasts, providing superior protection against extreme conditions and ensuring your engine remains safe and efficient.
