RADIATOR STOP LEAK
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
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.
Radiator Stop Leak is compatible with all Ethylene Glycol and OAT coolants as well as Aluminium and rubber hose safe.
It is recommended that Wynn’s Radiator Stop Leak is carried in recovery vehicles as an essential emergency repair item.
