What is waterless coolant

That limits the toxicity which comes with exposure to the product. Propylene glycol is used as a sweetener in many products, including medications. No harm is done if the product is accidentally ingested. When a vehicle leaks ethylene glycol, the results are very different, as it is poisonous to pets, small animals, and even children.

You receive a superior form of engine protection. Water changes its characteristics when exposed to a high enough temperature. If your engine runs hot, above degrees Fahrenheit, the water in your system begins boiling. Bubbles form next to the cylinder liners, flexing from the side thrusts provided by the pistons. If those bubbles implode, the coolant will impact the liner wall with enough force to eventually compromise the system. That causes the coolant to get into your oil sump and foul the system.

Instead of relying on unknown supplemental additives to stop this process, there is no water to vaporize in the waterless coolant.

That prevents voids and corrosion, promoting longer and healthier engine life in every vehicle. It provides a superior level of temperature protection for the engine. Vehicles in almost every climate benefit from the use of waterless coolant. That provides you with a better safety margin during engine operations.

Even when you use distilled water with your traditional antifreeze or coolant, there is still a threat of scale-forming to consider with your engine. There are no localized hot spots or boil-off concerns, which means you receive a cleaner operations profile.

It is a proven product with a history of success. Evans has manufactured their waterless coolant for more than 20 years, offering vehicle owners access to all the advantages of their product. The extended protections offered to engines are proven to work.

You eliminate the expansion of water as it cools, and its vaporization when heated. The threat of an engine block cracking disappears completely. Because of its higher boiling point, a waterless coolant remains in liquid form instead of vaporizing. That means you have fewer cooling system losses over time while preventing the issue of pitting. The hygroscopic nature of waterless coolant also means that any water trapped in the system will be absorbed into the fluid, giving you another layer of protection against internal corrosion.

Vehicles may warm up faster when using a waterless coolant. If you get tired of waiting for the heater to kick-in during the cold winter months, then a switch to waterless coolant may offer another benefit. Your vehicle warms up faster, which gives you more heat to use in the cab when the weather turns.

For owners living in cold weather environments, this benefit may increase their fuel efficiency rating by up to a half-mile per gallon.

Although warm weather drivers often see a drag on their fuel efficiency because of the added heat, any location which experiences seasonal weather changes should balance itself out over time. The cost of the waterless coolant is much higher. There are availability concerns to think about with waterless coolant. If a slow leak occurs with your vehicle, then you can make it home easy enough before repairing the issue. Just stop at any store, purchase replacement coolant, then make sure your reserves never get too low.

That option disappears for you when using waterless coolant. Availability is not as widespread as traditional antifreeze or coolant options because only authorized service providers have the product. Adding water eliminates the benefits of going waterless too. That means you must stock up on the product when you make the conversion to the waterless coolant. Even Evans Waterless Coolant offers a lower specific heat rating, which means a water-based product will create a faster result in comparison.

Compared to water, the specific heat capacity falls into a range between 0. The coolant creates a higher boiling temperature for the water, providing you with a layer of protection which is adequate unless the vehicle overheats. Some vehicles run cooler with a waterless coolant, especially if they are equipped with a high-performance engine. Increasing pressure raises the boiling point, which is why radiator caps are pressurized.

This bubble formation is called cavitation and is very bad for your engine. Put another way, the goal of any cooling system is to keep the internal metal temperatures under control. This can only happen if the liquid is in contact with the metal to carry the heat away. The bubbles of a boiling coolant act as insulation, holding in heat and preventing the coolant from doing its job. When you combine the limitations of water-based coolants with the fact that high performance motorcycle engines run at very high temperatures, and often have limited radiator size and air movement capacity, you have a recipe for very high internal temperatures and engine damage.

Some of the features of Evans Heavy Duty Coolant are:. Converting from your current water-based system to Evans Waterless Coolant is not terribly complex, but you do need their prep fluid, as it is very important to get all the water out of the system.

Basically, you drain the existing coolant, put in the prep fluid, run the engine for a few moments, drain the prep fluid, and repeat. Evans Waterless Coolant is widely used in diesel engines which generate very high internal temperatures , by the military in both land vehicles and aircraft, and in race cars and off-road race bikes. I have had no problems with overheating or losing coolant, and have become a real believer.

I highly recommend you give it a try. Check out Evans at: www. All rights reserved. Subscribe Login Sign Up Cart. Stops cylinder liner cavitation erosion pitting of the cylinder liner wall. Lasts the lifetime of the engine, if uncontaminated by water you never have to replace the coolant.
