Castrol Radicool P-OAT is a nitrite, amine, borate and silicate free antifreeze coolant for vehicles requiring Phosphated Organic Additive Technology (P-OAT), such as those from Japanese and Korean manufacturers. Aqueous solutions of Castrol Radicool P-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 P-OAT should be used at concentrations of between 33% and 50% dilution with distilled or de-ionised water to give optimum corrosion protection and freezing protection between -16°C and -37°C

Features:

• Suitable for use with a wide range of engines including those of aluminium, cast iron or combinations of those two metals. Also suitable for cooling systems made of aluminium, copper or their alloys
• Suitable for Japanese and Korean vehicles requiring P-OAT coolants
• Suitable for use where a coolant meeting Ford WSS-M97B57-A1 (Concentrate) or Ford WSSM97B57- A2 (Premix) is required
• Protects for up to 3 years and has the following advantages:
  • Excellent corrosion protection to protect metals used in cooling systems.
  • Superior cavitation protection prevents pitting wear of the cooling system.
  • Improved heat transfer through removal of silicates in the formulation.
  • Suitable for a wide range of applications, including automotive and heavy duty.

Specification/Approvals:

• ASTM D3306 (I) (Concentrate)
• ASTM D3306 (III) (Premix)
• ASTM D6210
• JASO JIS K2234
