Radicool P-OAT
Castrol Radicool P-OAT is a nitrite, amine, borate and silicate free antifreeze coolant for vehicles requiring Phosphated Organic Additive Technology (P-OAT). Aqueous solutions of Castrol Radicool P-OAT act as both antifreeze and coolant and offers excellent protection for the metals used in engine radiator systems, cylinder block heads, water pumps and heat exchangers.
Features & benefits
- Excellent corrosion protection to protect metals used in cooling systems.
- Long life usage – resulting from stable, non-depleting organic inhibitors.
- 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
Industry specifications
- ASTM D3306(I)
- ASTM D6210
- JASO JIS K2234
- Suitable for use in vehicles from Japanese and Korean manufacturers
- Suitable for use where a coolant meeting Ford WSS-M97B57-A1 is required
Radicool SF premix
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.
