WYNNS Radiator Flush Vehicle Cooling System Cleaner Rust Remover Additive 325ml

From Wynn’s, Radiator Flush is a high-performance vehicle cooling system cleaner designed to work in all coolants, including OAT coolant. Its acid-free formula delivers a dual-action clean, helping to remove scale while eliminating rust, deposits and oily residues. During use, it keeps dirt and particulates in suspension to support a thorough flush, and is stated to be safe for rubber hoses, seals and all metals within the cooling system.

Recommended for water-cooled systems on petrol and diesel engines, it is particularly effective when cleaning older cooling systems and is also suited to use when changing the cooling liquid, following the manufacturer’s recommendations. Used as directed, it helps restore optimal operation of the controls within the cooling system and is suitable for closed-circuit cooling systems.
