The coolant is normally controlled at conventional temperatures but functions perfectly well at higher temperatures, even considerably higher temperatures. Because naturally high 170 degree boiling point, it need for adding high pressure to the cooling system is eliminated. Reduction of "hot spots" & turbulent coolant flow£¬thereby improving the wetting of the metal surface by the coolant. 1, Anhydrous and stop corrosion completely 2, The high boiling point be 170 ¡æ and don't boiling. 3, The low solidifying point of -45 ¡æ ensures engines' normal operation in freezing weather.
