"Waterless" Coolant Extends Engine Life, Saves Fuel
Forget about overheating your cooling system if you use Evans waterless coolant. With a boiling point of 375 degrees and a freezing point of -40 degrees, your engine operates more efficiently and reduces the cooling load on radiator and fan, says Mark Stone, Evans Cooling Systems, Inc.
"Water-based coolants run at or near their boiling point, while ours has a reserve capacity to cool the engine even on the hottest day of the year," says Stone. "Cooling goes from high pressure to low pressure with our waterless coolant. You don't have pressure on radiator caps, seals or gaskets. Life expectancy of the cooling system is extended, and our coolant is not toxic."
Stone points out that 6,500 kids end up in the hospital each year, and 650 die due to poisoning from antifreeze-treated coolant.
He adds that water-based cooling systems also contribute to pump and cylinder liner cavitation and corrosion, as well as hot spots that can damage engines. Cavitation alone can require an engine rebuild. When Deere tested Evans no-water coolant along with multiple water-based coolants, the results were impressive.
"Deere used their most cavitation prone engine and ran it for 250 hrs. before tearing it down and examining the liners for pits," explains Stone. "A passing score was 200 pits, and ours was 21. We were 75 percent better than the best water-based coolant."
He points out that a high boiling point can be important in heavy equipment running in dusty, dirty conditions. "Field conditions can clog a radiator and cause a water-based cooling system to overheat," says Stone. "With ours, you have time to get back to a maintenance area where you can clean the radiator out."
The combination of running at a higher temperature than possible with water-based systems and less need for energy draining fans also saves fuel. Independent evaluations on heavy trucks have shown fuels savings of as much as 7.2 percent due to reduced fan time when fan temperature is raised to 230 degrees. Testing at Auburn University eliminated the fan time variable and still produced a 3 percent improvement in fuel efficiency.
Evans offers HDTC, a heavy-duty formulation with special additives for heavy diesel engines. It's recommended for large tractors, combines and heavy trucks. It's priced at $42.95/gal. NPG+ is designed for diesel and gas engines, such as cars, pickups and smaller tractors. It's priced at $39.95 per gal. However, a flush product is recommended before refilling smaller cooling systems with the waterless coolant.
"While the price for our waterless engine coolant may seem high, it quickly pays for itself in reduced engine wear and fuel," says Stone. "Plus, it's a lifetime coolant. It doesn't become contaminated, and future replacement and disposal costs are eliminated. It stays stable and in suspension during storage as well as use."
