Description
Castrol Radicool Si-OAT Premix is a ready to use engine coolant and antifreeze. It is a nitrite, amine and phosphate freeantifreeze coolant with added silicate for the latest vehicles requiring silicate containing OAT technology. Aqueoussolutions 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 Premix provides year round corrosion protection, and offers freezing protection down to -37°C.
Application
Castrol Radicool Si-OAT Premix has been developed to provide total protection for the metals used in the engine radiator systems, cylinder block heads, water pumps and heat exchangers.
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 Si-OAT Premix for the first time, ensure that the cooling system has been adequately flushed with clean water.
Advantages
Castrol Radicool Si-OAT protects for up to 3 years and has:
Excellent low temperature protection
Provides superior protection against all forms of corrosion
Eliminates deposit formation, because of its phosphate free formulation
