ANTIFREEZE AND COOLANTS

coolants

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.

Radicool Premix

castrol Radicool Premix

Replaces Castrol Radicool


Premixed engine coolant (33%), for both petrol and diesel engines that cools and protects.


Application


For a wide range of petrol and diesel engines


Features & Benefits

 

  • A complete fill, ethylene glycol premix coolant i.e., “ready-to-use – simply pour“. It is premixed to 33 vol% concentration.
  • Improved engine corrosion protection helping to resist the formation of rust while protecting alloy heads and engines.
  • Improved protection against cavitation in water pumps and hot spots (e.g., behind exhaust ports) in aluminium cylinder heads.
  • Excellent hot weather protection - helps prevent the risk of the engine coolant boiling, leading to coolant loss and possible engine damage and subsequent failure.
  • Excellent cold weather protection - reduces the real risk of coolant freezing solid in the engine coolant system and severely damaging engines and/or radiators.
  • Easy to use.

Radicool NF

Radicool NF

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.


Features & Benefits

 

  • Protects for up to 5 years, 9000 hrs / 600,000 kms.
  • Excellent low temperature protection
  • Provides excellent protection against corrosion
  • Efficient lubrication of water pumps
  • Compatible with conventional seal and hose materials used in engine cooling systems
  • Contains bittering agent.
  • Has many OEM approvals

Radicool SI-OAT

Radicool Si-OAt

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.

 

Advantages

 

  • Excellent low temperature protection.
  • Provides superior protection against all forms of corrosion.
  • Minimises deposit formation, because of its phosphate free formulation.
  • Approved for use in Euro 6 generation truck and bus engines.
