Antifreeze and coolants role in maintaining maximum engine performance is extremely important. The life of an engine, particularly high performance diesel engines, can be shortened or suffer damage, by not using the right antifreeze/coolant and not maintaining the correct levels in the cooling system.
Castrol’s antifreeze/coolant range includes the approved and latest technology products offering outstanding protection and longer engine life.
Engine coolant concentrate, for both petrol and diesel engines that cools and protects.
For a wide range of petrol and diesel engines.
Advanced Performance Series
Premixed engine coolant (33%), for both petrol and diesel engines that cools and protects.
For a wide range of petrol and diesel engines
Advanced Performance Series
An antifreeze concentrate coolant formulated using hybrid technology for the modern performance engines of cars and trucks.
Castrol Radicool NF has been developed to meet the growing demand from engine and vehicle manufacturers for a higher performance coolant that minimises environmental impact.It provides excellent protection against corrosion, and because it contains no phosphate, the problems of deposits in some modern performance engines are eliminated.
This coolant 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.
A ready to use antifreeze coolant formulated using monoethylene glycol and selected additives, free from nitrite, amine and phosphate inhibitors. It uses hybrid technology for the modern performance engines of cars and trucks. Castrol Radicool NF premix is designed to meet and generally exceed the requirements of most major European engine manufacturers. This product requires no customer dilution therefore ensures the correct concentration is always used.
Long-life ready to use engine coolant based on monoethylene glycol with advanced organic additive corrosion inhibitor technology (OAT). It is suitable for a wide range of vehicles including cars, trucks and buses using both petrol and diesel engines. Radicool SF Premix requires no customer dilution ensuring that the correct concentration is always used.
Long-life coolant formulated using advanced organic acid technology (OAT). It is suitable for use in a wide range of vehicles, including cars, trucks and buses. It can be used in both petrol and diesel engines. Radicool SF-O works over a wide operating temperature range for effective engine cooling in all climates.
A nitrite, amine and phosphate free antifreeze coolant with added silicate for the latest vehicles requiring silicate containing OAT technology. Aqueous solutions of Castrol Radicool Si-OAT act as both antifreeze and coolant and offer excellent corrosion protection to all metal parts found in the cooling systems of internal combustion engines.
