Castrol Radicool SF-O Premixed Extended Life Coolant
Castrol Radicool SF-O Premix is a silicate free ready-mixed antifreeze, formulated using advanced organic acid technology (OAT), and works over a wide operating temperature range for effective engine cooling in all climates.
Castrol Radicool SF-O Premix requires no customer dilution therefore ensures the correct concentration is always used, providing year round protection against corrosion, and offers freezing protection down to -36°C.
Castrol Radicool SF-O Premix is a long-life coolant based on monoethyleneglycol, it is suitable for use in a wide range of vehicles, including cars, trucks and buses, for both petrol and diesel engines. In contrast to traditional antifreeze coolants, Castrol Radicool SF-O Premix does not contain Amines, Nitrites, Phosphates, Silicates or other inorganic inhibitors.
For maximum performance Castrol Radicool SF-O Premix should not be mixed with other coolants. It is therefore recommended that cooling systems should be drained and flushed before re-filling with diluted Castrol Radicool SF-O Premix.
