Radiator Leak Stop is a unique mixture of natural fibres and surfactants. Together, the substances ensure that hairline cracks and pores in radiators and the cooling system are sealed. Radiator Leak Stop is suitable for all cooling systems, and is used to seal off minor existing leaks in the cooling system. Radiator Leak Stop can also be used preventatively, in which case the product provides the cooling system with instant protection against future leaks.
Instructions for use:
Add a bottle of Radiator Leak Stop to the cooling system with a cold running engine. Turn on the heating and wait until the engine reaches its operating temperature. If the system is dirty, clean it first using Radiator Cleaner.
