Race tracks prohibit Evans products because they are flammable and slippery when spilled. Viscosity is 3-4 times higher than what OEM water pumps are rated to accommodate.Ĭoolant flow rate through radiator tubes is reduced by 20-25% due to the higher viscosity. Specific heat capacity of Evans waterless products ranges from 0.64 to 0.68, or about half that of water.Įngine octane requirement is increased by 5-7 numbers.Ĭomputerized ignition must retard engine timing by 8-10o to prevent trace knock.Īccelerated recession of non-hardened valve seats in older engines is possible, due to brinelling. Reprogramming ECU fan temp settings is mandatory to prevent the fan from running continuously. Stabilized coolant temps are increased by 31-48oF, versus straight water with No-Rosion. Inhibitor deposition occurs on aluminum surfaces, which could cause issues in some radiators.Įngines run 115-140oF hotter (at the cylinder heads) with Evans products.
Thoughts?Ĭonversion costs of $259 if you do it yourself, or over $400 if you pay a shop to do it.ĩ7%+ removal of all previous coolant is mandatory in order to prevent corrosion.
#Test strips for evans waterless coolant full
When I spoke to an Evans rep they said if the car's not already overheating, there's no reason for this fluid to overheat in the car.įYI, this fluid requires a full flush, dry block, then they fill it up with this stuff. Is this more or less correct? I know there's variance in the temperature of course, but I've heard of a *few* accounts of people saying it ran hotter in their cars. I don't understand how a coolant would run hotter unless its heat dispersion was bad enough to overwhelm the system. Can anyone explain to me why, within a normally operating system, any fluid, whatever fluid that is in there would run hot?Īs far as I can understand, in general, the thermostat monitors temperature, opens up when it reaches the operating temperature and lets coolant run through the system, if under operating temperature it will keep it in the block. I have heard, however, that this coolant runs hotter than a "typical" coolant (evos use the green one). Supposedly the main benefits are that it doesn't run water, which prevents any sort of issues with corrosion, and that it is non-toxic. Did a quick scan of this but did not come across any posts - sorry if missed.
