Castrol Radicool Premix
Castrol Radicool Premix is a ready to use engine coolant that requires no customer dilution therefore ensures the correct concentration is always used. Castrol Radicool Premix provides year round protection against corrosion, and offers freezing protection down to -36°C. For optimum performance this product should be replaced after 1 year.
Strong corrosion protection helps preserve metal surfaces against rust and chemical attack, supporting equipment longevity in environments where moisture or aggressive contaminants may be present.
The formulation is engineered to maintain engine and component cleanliness, helping to prevent deposit build-up and supporting efficient operation throughout the service interval.
Castrol Radicool Premix can be used in both petrol and diesel engines with aluminium or cast iron engines. 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 Premix for the first time, ensure that the cooling system has been adequately flushed with clean water before use.
Castrol Radicool Premix is manufactured to Castrol’s standard tolerances; users should consult the safety data sheet for handling, storage and disposal guidance.
