Castrol Radicool SF Red Concentrate Antifreeze

Castrol Radicool SF, developed with Organic Acid Technology (OAT), is a long-lasting red antifreeze that does not contain silicate, phosphate, nitrite, amine, and borate. It provides Its advanced formula prevents calcium deposits from hard water sources, inhibits sludge formation in the cooling system, and offers more efficient heat transfer. This extends the life of critical components like the radiator, thermostat, and water pump. Long replacement intervals reduce maintenance costs and create a one-type solution for mixed fleets.

For optimal performance, it is recommended to mix with pure water. A minimum of 33% concentration is required for effective corrosion protection. Suitable for four-season use in all climate conditions.
