A long-life coolant based on monoethylene glycol with advanced organic acid inhibitor technology.In contrast to traditional antifreeze coolants, Castrol RADICOOL SF does not contain amines, nitrites,phosphates, silicates or other inorganic inhibitors.Castrol RADICOOL SF provides excellent corrosion protection particularly to those engines employing light metals.

It is suitable for a wide range of OEMs.Castrol RADICOOL SF works over a wide operating temperature range for effective engine cooling in all climates, and offers freezing protection between -18°C and -37°C depending on concentration.RADICOOL SF Premix has been diluted to 50% concentration with distilled water, providing freezing protection down to -37°C.

FEATURES & BENEFITS

• Special inhibitor package enables longer drain intervals with excellent protection against corrosion,cooling system blockage, overheating and freezing

• Suitable for use in engines employing cast iron, aluminium, copper or combinations of these metalsused in modern engine designs. It is also compatible with all standard rubber hoses, gaskets and sealsused within the cooling system

• Possesses a longer operational life by allowing extended drain intervals of 3 years plus

• Longer drain intervals mean reduced cost and less possibility of harm to the environment

• Excellent protection against cavitation corrosion and effective water pump lubrication, reducing wear and noise

• Additive technology used prevents the build up of calcium deposits (scale) from use of hard water,thereby reducing possibility of radiator blocking and restricted flow of coolant. This technology also improves the fluid’s heat transfer properties ensuring engines run at optimum temperatures

• Contains a bittering agent to deter from accidental ingestion.
