ENOC EN X-TREME COOL EC50 is a premium long-life coolant that is based on advanced technology of organic acid inhibitors approved by numerous Original Equipment Manufacturers (OEMs) worldwide. This coolant technology provides long-life corrosion protection for all engine metals, including aluminum and ferrous alloys and is recommended for use in cooling systems of liquid cooled automotive combustion engines. The corrosion inhibitors contained in ENOC EN X-TREME COOL EC50 have very low depletion rates, unlike traditional silicate based technologies; proven to provide protection for at least 250,000 km (ca. 2000 hours) for passenger cars and light duty vehicles. Exempted from potentially harmful additives such as nitrites, amines and phosphates, the coolant will contribute to a safer environment. The 50% premix ENOC EN X-TREME COOL EC50 provides protection over wide operating temperature range for effective cooling in all climates. APPLICATIONS: Modern passenger car engines fitted with turbochargers, supercharged, GDI & other high output engines. Mixed fleets where both light duty and heavy duty trucks are present All engines employing cast iron, aluminum, copper or combination of these metals used in modern engines. It is also compatible with all standard rubber hoses, gaskets and seals used within the cooling system.
