Castrol Radicool SF Premix is a long-life ready to use coolant based on monoethyleneglycol with advanced organic acid inhibitor technology. In contrast to traditional antifreeze coolants, Castrol Radicool SF Premix does not contain amines, nitrites, phosphates, silicates or other inorganic inhibitors.
Castrol Radicool SF Premix provides excellent corrosion protection particularly to those engines employing light metals. It is suitable for a wide range of OEMs equipment.
Castrol Radicool SF Premix works over a wide operating temperature range for effective engine cooling in all climates, and offers freezing protection down to -37°C.
The special inhibitor package used in Castrol Radicool SF Premix enables longer drain intervals with excellent protection against corrosion, cooling system blockage, overheating and freezing. It is especially suitable for use in engines employing cast iron, aluminium , copper or combinations of these metals used in modern engine designs. It is also compatible with all standard rubber hoses, gaskets and seals used within the cooling system.
Castrol Radicool SF Premix possesses a longer operational life by allowing extended drain intervals of up to 5 years. Longer drain intervals mean reduced cost and less possibility of harm to the environment. Castrol Radicool SF Premix provides excellent protection against cavitation corrosion and effective water pump lubrication, reducing wear and noise.
The additive technology used in Castrol Radicool SF Premix 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 fluids heat transfer properties ensuring engines run at optimum temperatures.
