Castrol Radicool SF works over a wide operating temperature range for effective engine cooling in all climates. Castrol Radicool SF should be used at concentrations of between 33% and 50% dilution with purified water to give optimum corrosion protection and freezing protection between -18°C and -36°C. Show more
