Castrol Premium Cool Plus is an ethylene glycol based engine coolant concentrate containing a balanced mixture of organic acid and inorganic corrosion inhibitors specially designed to service the requirements of a broad range of heavy duty diesel engines, particularly those with wet liners.

Castrol Premium Cool Plus is a low silicate, phosphate and amine free formulation providing extended service life protection for Lead Solder, Aluminium, yellow metal and ferrous alloys.

The inclusion of a number of corrosion inhibitors prevents corrosion occurring in the number of dissimilar metals found in modern engine cooling systems.

Castrol Premium Cool Plus satisfies or exceeds major industry coolant standards and is satisfactory for use in major U.S., European and Japanese heavy duty diesel engines.

When choosing coolant, please refer to your owner�s handbook and the product specifications shown below.

Castrol Radicool Concentrate is an engine coolant concentrate for year-round use in both petrol and diesel vehicles with aluminium or cast iron engines. This coolant can be diluted to 33 vol% concentration with purified water to give freeze protection down to -18°C, or at a 50 vol% dilution to provide freeze protection down to -36°C if required.

To maintain optimum performance this product should be drained and replaced after 2 years.

Castrol Radicool Concentrate is compatible with all materials normally used in automotive cooling systems including hoses, gaskets, seals, plastics and all metal components. It may be used in a variety of vehicles including passenger cars, SUVs and light commercial vehicles.

In the majority of cases, coolants are not compatible and should not be mixed with other coolants unless directed by the equipment manufacturer. If using Castrol Radicool for the first time, ensure that the cooling system has been adequately flushed with clean water before use.

When top up of the cooling system is necessary, add only Castrol Radicool concentrate mixed with demineralised water at the recommended concentration. For improved anti-boil and freeze protection, dilute Radicool concentrate at 50 vol%.

When choosing coolant, please refer to your owner�s handbook and the product specifications shown below.

Castrol Radicool NF is an antifreeze concentrate 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.

This coolant should be used at concentrations of between 3% and 50% dilution with purified water to give optimum corrosion protection and freezing protection between -18°C and -36°C.

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.

In addition to providing excellent corrosion and low temperature protection, the use of the recommended level of anti-freeze will significantly reduce the likelihood of wet cylinder liner pitting due to "cavitation erosion". Cavitation erosion is caused by the implosion of air bubbles present in the coolant and which are attracted to the liner outer surface. These bubbles implode resulting in the removal of minute amounts of liner material, which if allowed to continue unchecked will result in liner porosity and severe engine damage.

In the majority of cases, coolants are not compatible and different types should not be mixed unless directed by the equipment manufacturer. If using Castrol Radicool NF for the first time, ensure that the cooling system has been adequately flushed with clean water.

When choosing coolant, please refer to your owner�s handbook and the product specifications shown below.

Castrol Radicool Si-OAT Premix is a ready to use engine coolant and antifreeze. It is a nitrite, amine and phosphate free antifreeze coolant with added silicate for the latest vehicles requiring silicate containing OAT technology. Radicool Si-OAT Premix is both antifreeze and coolant and offers excellent corrosion protection to all metal parts found in the cooling systems of internal combustion engines.

Castrol Radicool Si-OAT Premix provides year round corrosion protection, and offers freezing protection down to -37°C.

Castrol Radicool Si-OAT Premix has been developed to provide total protection for the metals used in the engine radiator systems, cylinder block heads, water pumps and heat exchangers.

In the majority of cases, coolants are not compatible and should not be mixed with other coolants unless directed by the equipment manufacturer. If using Castrol Radicool Si-OAT Premix for the first time, ensure that the cooling system has been adequately flushed with clean water.

Castrol Radicool Si-OAT Premix is a ready to use dilution of Radicool Si-OAT, which is formally approved by Volkswagen in addition to MAN and Mercedes Benz.
