Castrol Radicool Premix
Castrol Radicool Premix is a ready to use engine coolant for both petrol and diesel engines with aluminium or cast iron engines. As it requires no customer dilution, the correct concentration is always ensured. It provides year round protection against corrosion and offers freezing protection down to -19°C. Radicool Premix is a mixture of monoethylene glycol, purified water, and selected chemical agents, and contains no nitrites, amines, or phosphates. For optimum performance, this product should be replaced after 1 year.
