The cooling system is one of the most important systems in a vehicle. So, having the right product for it is key. Since engines run on energy produced by heat, the lack of a proper coolant will result in the engine overheating and destroying itself. Water is the traditional cooling agent in any engine. And though it works, it isn’t ideal. Water has limitations, including its boiling point, expansion rate, and the inevitable corrosion it generates. Traditional anti-freeze is a great alternative, but it still shares many of the same limitations as water.
A Better Option – Coolant
That’s why Evans Cooling Systems Waterless Engine Coolant is something of a miracle product. Much like typical antifreeze, it’s glycol based. But it contains no silicates or phosphates and requires no supplemental coolant additives (SCA) to maintain the coolant’s properties. Additionally, waterless coolant has a boiling point of 375°F and a freezing point of -40°F. Compare that to water which boils at 212°F and freezes at 32°F, and 50/50 coolants which boil at ~265°F (with a pressure cap) and freeze at around -34° F. Even better, Evans’ product has absolutely no corrosive characteristics. This means no rust or buildup will occur in the water jackets or in the radiator.
Many people already know the pressure that water produces in a cooling system is taken advantage of. This pressure helps to push the water against any surfaces it may have trouble reaching otherwise. But because the boiling point is so high for waterless coolant, Evans cooling products don’t produce the pressure that water does. Though fast mapping may suggest water is superior in this sense, this isn’t the case. Evans’ product has a much lower surface tension than that of water, meaning it can slide across surfaces much easier. Therefore, the additional pressure isn’t actually necessary.
The use of regular antifreeze on a racetrack doesn’t go over lightly. When antifreeze spills onto the track it can be a real drag to clean up. Because of this, most racers use water instead. However, the NHRA approves the use of Evans Waterless Coolant because it’s just as easy to clean up as water. A lot of racers, like Jim Marino who runs an eight second bracket car, use Evans Coolant over water in their cars.
But the NHRA doesn’t just allow the use of Evans cooling products on their drag strips. In fact, they run a contingency event with Evans Coolant as the sponsor! When all is said and done, both the winner and runner up are rewarded cash prizes by Evans Cooling. It’s a great way for the company to thank racers for using their products and put a little money back into customers’ pockets.
Evans Cooling has a home beyond the drag strip, though. The company offers its waterless coolant for all sorts of applications. Standard motorheads get to have fun but so do the enthusiasts in powersports, the offroad life, and heavy-duty roles. The product can even be run in old school muscle cars. For each user, Evans provides an application-specific product to optimize each person’s experience.
Conversion Requirements and Recommendations
The one drawback to this product is that you can’t simply add it to a cooling system that already has water in it. Evans states that all of the existing water needs to come out, which adds a few minor steps to the process. Evans recommends opening each drain cock in order to completely rid the system of any water. Additionally, the company suggests leaving the valves open for at least one day to allow the system to properly dry out. Evans does offer a prep fluid that’s designed to give the system a thorough cleaning by detecting and draining any remaining water.
The company also recommends using a refractometer to measure the final water content after installation using a Brix scale. If the test shows there is more than 3% water in the coolant, some corrective action will need to take place to ensure the product is offering peak performance.
Every part of an engine is designed to work as hard and consistently as possible. And the cooling system is of no exception. A hot engine is on a fast track to destruction, and overheating is one of the worst possible outcomes. The limitations and consequences of using water-based coolant can add to this headache and have a serious effect on the longevity of your vehicle. So, check out Evans Waterless Engine Coolant and enjoy high-performance reliability without the shortcomings of traditional cooling agents.
