Description Carcoolant 774F (Extended Life Coolant) - mixed with the appropriate amount of water - is used as a cooling and heat transferring fluid in combustion engines. Excessive heat is transferred via the fluid to the radiator where the mixture is cooled by means of airflow. Carcoolant 774F is an ethylene glycol based fluid that provides maintenance-free protection against freezing and boiling but also against corrosion. Extended coolant life, often for the whole life of the engine or vehicle, is obtained through the use of virtually nondepleting corrosion inhibitors.

Based on silicate-free aliphatic additive technology, Carcoolant 774F provides long-life corrosion protection for all engine metals, including aluminium and ferrous alloys. During extensive fleet testing, the synergistic combination of mono- and dicarboxylates present in this coolant, has proven to provide protection for at least 650,000 km (ca. 8,000 hours) in truck & busapplication or 250,000 km (ca. 2,000 hours) for passenger cars or 32,000 hours (or 6 years) for stationary engines. It is recommended to change the coolant every five years or when above mileages or operating times are reached, whichever comes first. Carcoolant 774F provides long-life protection against all forms of corrosion by the use of optimised organic corrosion inhibitors. Excellent and lasting high temperature corrosion protection is provided for the aluminium heat transfer surfaces contained in modern engines. The inhibitor package of Carcoolant 774F offers excellent cavitation protection even without using nitrite or nitrite-based supplemental coolant additives (SCA’s).

Carcoolant 774F provides long-life frost and corrosion protection. To ensure good corrosion protection, it is recommended to use at least 33 vol.% of Carcoolant 774F in the coolant solution. This provides frost protection to -20 °C. Typical mixtures in Northern Europe are 50/50, offering frost protection down to -40 °C. Mixtures with more than 70 vol.% Carcoolant 774F in water are not recommended. The maximum frost protection (about -69°C) is obtained at 68 vol.% Carcoolant 774F. Carcoolant 774F may be used with confidence in engines manufactured from cast iron, aluminium or combinations of the two metals, and in cooling systems made of aluminium or copper alloys. Carcoolant 774F is particularly recommended for hi-tech engines, where high temperature aluminium protection is important.
