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.
Low silicate ethylene glycol based engine coolant – phosphate and amine free formulation providing extended service life protection for lead solder, aluminium, yellow metal and ferrous alloys.
For US, European and Japanese turbocharged and naturally aspirated diesel engines, particularly wet liner engines, operating in on-highway and off-road environments and arduous city stop- start driving conditions.
Not generally recommended for petrol engines. For Mercedes Benz, use Radicool NF.
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.
A long-life ready to use coolant based on monoethylene glycol with advanced organic acid inhibitor technology. In contrast to traditional antifreeze coolants, Castrol Radicool SF Premix does not contain amines, nitrites, phosphates, silicates or other inorganic inhibitors.
