Wynn’s Radiator Stop Leak is a unique blend of non-ferrous fibres and surface active agents which combine to plug hairline cracks and pinholes up to 0.7mm which are associated with cavitation pitting and corrosion. It will not cause any blockage of the radiator core or cooling matrix, nor will it harm any cooling system components.
