Castrol Radicool P-OAT is a high-performance, nitrite, amine, borate, and silicate-free antifreeze coolant designed to meet the specific needs of modern vehicles, particularly those from Japanese and Korean manufacturers. This Phosphated Organic Additive Technology (P-OAT) formulation delivers superior corrosion protection for all metal components in the cooling system, including aluminium, cast iron, copper, and their alloys. The coolant is ideal for a variety of applications, including automotive and heavy-duty vehicles, offering freezing protection between -16°C and -37°C. Castrol Radicool P-OAT also provides up to three years of protection, safeguarding the cooling system against wear, corrosion, and cavitation.

Features:

• Excellent Corrosion Protection – Safeguards metals in the cooling system, extending component life.
• Superior Cavitation Protection – Prevents pitting wear in the cooling system.
• Improved Heat Transfer – Enhanced heat transfer through the removal of silicates.
• Long-Lasting Protection – Provides up to 3 years of protection for a wide range of vehicle applications.
• Versatile Compatibility – Suitable for engines made of aluminium, cast iron, or combinations of both, as well as cooling systems made of aluminium, copper, or their alloys.

Specifications/Approvals:

• ASTM D3306 (I) (Concentrate)
• ASTM D3306 (III) (Premix)
• ASTM D6210
• JASO JIS K2234
• Ford WSS-M97B57-A1 (Concentrate) / Ford WSS-M97B57-A2 (Premix)
