Radiator Stop Leak

Small leaks from stone chips, porous solder joints or hairline cracks in water cooled engine cooling systems are hard to detect. They are often only noticed when the coolant level drops. This product spreads through the system and seals these leaks immediately and permanently. It also protects the combustion chamber from damage caused by coolant entering it. It is compatible with all common coolant additives and antifreeze. It is suitable for all cooling and heating systems with or without water filters, except low conductivity coolants. It can also be used as a preventive measure.

150 ml is sufficient for up to 10 litres of coolant
