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. It is suitable for a wide range of vehicles including cars, trucks and buses using both petrol and diesel engines. It is therefore particularly suitable for use in mixed fleets.

Castrol Radicool SF works over a wide operating temperature range for effective engine cooling in all climates.

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