Castrol’s Radicool SF Premix provides excellent corrosion protection particularly to engines employing light metals. It works over a wide operating temperature and it enables longer drain intervals of 3 years plus. It is especially suitable for use in engines employing cast iron, aluminium, copper or combinations of these metals used in modern engine designs.  It is also effective in water pump lubrication. The Radicool SF Premix prevents build up of calcium deposits from use of hard water thereby preventing radiator blocking and restricted flow of coolant.

Castrol Radicool SF

Castrol Radicool SF is a long-life coolant based on monoethyleneglycol with advanced organic acid inhibitor technolgy. In contrast to traditional antifreeze coolants, Castrol Radicool SF does not contain amines, nitrites, phosphates, silicates or other inorganic inhibitors.
