Castrol Radicool Pre Mix. This Pre Mixed Engine Coolant (33%), for both petrol and diesel engines used in cars, 4WD's and light commercial vehicles, cools and protects for up to 4 years.

This ready-to-use - simply pour Coolant is premixed to a 33% mass glycol concentration. It provides improved engine corrosion protection helping to resist the formation of rust while protecting alloy heads and engines, improved protection against cavitation in water pumps and hot spots (eg behind exhaust ports) in aluminium cylinder heads and has excellent hot/ cold weather protection. In Hot weather it helps prevent the risk of the engine coolant boiling, leading to coolant loss and possible engine damage and subsequent failure and in Cold weather it reduces the real risk of coolant freezing solid in the engine coolant system and severely damaging engines and/or radiators. Suitable for a wide range of petrol and diesel engines.
