One of the questions most frequently asked of the Evans technical staff is, “How much cooler (or warmer) will my engine run with Evans?”
The answer: Most often, there will NOT be a noticeable change in the operating temperature.
Under normal conditions, a typical car driven daily with standard equipment running with Evans Coolant will operate in the same range as 50/50 (ethylene glycol/water) coolant. Although the boiling point of Evans is 375°F, that doesn’t mean it will reach higher operating temperatures. What it does mean is that Evans waterless coolant will remain a liquid, and maintain efficient heat transfer well past the point where water-based coolant will boil (aka its failure point).
