was wandering if anyone has ever tried the evans coolant. is it worth the extra cost. says it will increase fuel milage, but dont understand how that could be. what is your opinions on this?
I think any claims of fuel economy increase are a bunch of bull, and even more importantly, that motor is made to run specifically on GOLD motocraft coolant or equivilant. if you run anything else in it, you risk pitting, cavitation, premature failure of cooling system componants, and possible eating away at the back side of the cylender wall. I would reccomend just sticking with what it has, and i reccomend servicing it at 60k instead of 100k, but im anal about maintanence........Marc
Fuel economy claims are not all automatically bull. Big rigs have seen a 5% increase in MPG simply by turning the fan on at a higher temperature, relieving the engine of the fan load. If the combustion chamber temperature is allowed to be higher, fuel can be burned more completely which also results in lower emmissions. In gas engines, a leaner fuel/air mixture can be used with Evans. Instead, manufacturers richen the mixture as a means of cooling the metal surfaces. For both diesel and gas, great gains in economy could be made if OEMs designed their engines to take advantages of Evans' unique properties.
Cavitation, pitting (cavitation erosion), and seal leaks are the result of the properties of water. Cavitation is specifically brought on by the low boiling point. Pressure raises the boiling point of liquids. The pump has a low pressure side. This area boils at a lower temperature because of the lower pressure. This cavitation interupts the coolant flow, furthur inhibiting cooling. The cylinder walls of a diesel experience a lot of vibration. This vibration on a micro level raises and lowers the pressure on the coolant causing it to form and collapse vapor bubbles. This collapsing of water vapor is the violent action that causes cavitation erosion and the need to replace cylinder liners. Evans has gone well over 500,000 miles in class 8 diesels without being exchanged, added to or refreshed. Cylinder liners didn't need replacing.
Manufacturers have been protecting their corporate owned brands; that's no reason to limit yourself to their products.
I've been racing with Evans Coolant for years and it's in all my other liquid cooled vehicles.
There was a member that called the company trying to get info about there product. They told him to NOT use it, that on the 6.0 motor it will cause harm to the studs and gaskets. I never followed up on the thread so i dont know where it went from there.
The company is worried about people getting the conversion right. If there is water left in the system, Evans will act just like a water based coolant. Big engines are hard to convert because they hold so much coolant in the block and elsewhere after draining. With a diesel, you want 3% H2O or less which can be challenging especially if you don't have the tool for reading the water content. The studs and gaskets issue would exist if there was water left behind because Evans doesn't have (need) the corrosion inhibitors that other coolants contain. I've done a number of conversions and it can be frustratingly involved but when it's done right, very satisfying.
