Castrol Radicool SF Premix Coolant is a high-performance, long-life coolant designed to meet the demanding needs of modern engine cooling systems. Unlike traditional antifreeze coolants, Radicool SF uses advanced organic acid inhibitor technology and does not contain amines, nitrites, phosphates, silicates, or other inorganic inhibitors. It offers excellent protection against corrosion, overheating, and freezing, making it suitable for a variety of engine designs, including those using light metals like aluminium and copper. Radicool SF works over a wide temperature range, offering freezing protection down to -37°C, and its 50% pre-diluted concentration makes it ideal for quick use. The formulation also includes additive technology to prevent calcium deposits, keeping the cooling system flowing freely and efficiently.

Features:

• Advanced inhibitor package enables longer drain intervals with superior protection against corrosion, cooling system blockage, overheating, and freezing.
• Compatible with engines using cast iron, aluminium, copper, or combinations of these metals, and suitable for modern engine designs.
• Longer operational life with drain intervals extending beyond 3 years, reducing costs and environmental impact.
• Protects against cavitation corrosion and provides effective water pump lubrication, reducing wear and noise.
• Prevents calcium deposits from hard water, ensuring smooth coolant flow and better heat transfer for optimal engine temperatures.
• Includes a bittering agent to deter accidental ingestion.
