The cooling system on a car is often the most neglected part, but is actually one of the most important. A significant number of engine failures are related to coolant system malfunctions. Taking care of the cooling system reduces downtime and the inevitable cost of repairs. Use of the correct dilution for the climate your car operates in is key to ensure total protection.
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
A general purpose ethylene glycol based coolant with corrosion inhibitors to protect aluminium alloys, copper and cast iron engine components.
Suitable for the majority of cars and light commercial vehicles with petrol and diesel engines. Has an in-vehicle service life of 4 years / 250,000 kilometres.
Mix with equal parts of water for optimum performance.
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 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.
Castrol Radicool Si-OAT 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.
