Castrol Radi Cool Premix Summer Coolant and Antifreeze (4L)

Castrol Radicool Summer coolant and antifreeze. Castrol Radicool is a concentrated engine coolant for use in both petrol and diesel engines with aluminum or cast-iron engines. This coolant can be mixed using 33% concentration with purified water to give frost protection to -18 deg C, however it is recommended to use a 50% dilution to provide optimum corrosion protection and freeze protection down to -36 deg C. At these concentrations this coolant will provides year-round protection. To maintain optimum performance this product should be replaced after 1 year. ApplicationCastrol Radicool is a mixture of monoethylene glycol and selected chemical agents. It contains no nitrites, amines or phosphates. Because it contains no phosphate, the problems of deposits in some modern performance engines are reduced. Castrol Radicool provides: protection against hard water effective engine cooling without boiling; protection against corrosion of the alloys used in the cooling system of modern vehicles; compatibility with conventional seal and hose materials used in engine cooling systems; protection against cavitation corrosion; efficient lubrication of water pumps contains bittering agentIn most cases, coolants are not compatible and should not be mixed with other coolants unless directed by the equipment manufacturer. If using Castrol Radicool for the first time, ensure that the cooling system has been adequately flushed with clean water before use. Product Performance ClaimsASTM D3306BS 6580: 2010JIS K2234.
