Castrol Radicool SF Coolant 1L

Castrol Radicool SF is a long-life coolant based on monoethyleneglycol with advanced organic acid inhibitor technolgy. 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.

The special inhibitor package used in Castrol Radicool SF 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 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. Castrol Radicool SF provides excellent protection against cavitation corrosion and effective water pump lubrication , reducing wear and noise.
The additive technology used in Castrol Radicool SF 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.

Castrol Radicool SF should be diluted between 33% and 50% concentration, with deionised/distilled water. For best all round performance, it is recommended that a 50% mixture in water is used. Concentrations higher than 70% volume are not recommended.

To main it's performance, Castrol Radicool SF should not be mixed with other coolants. It is recommended that cooling systems should be drained and flushed before re-filling with diluted Castrol Radicool SF.
