A special additive in the coolant is a sealant for the cooling system of internal combustion engines (ICE) and the interior heating system. Suitable for any liquid-cooled internal combustion engine with radiators made of any materials (aluminum, copper, plastic and composite, etc.). It is a mixture of metal polymers and special fibres and is designed to eliminate leaks in the system.


Application: Start the engine at idle speed and let it warm up to operating temperature, turn on the interior heating. Shake the contents of the bottle thoroughly and pour it into the expansion tank of the cooling system (or into the radiator). One 325 ml bottle is sufficient for a 12 litre system. Let the engine idle for 10 minutes. If the leaks are not eliminated within 3 days, mechanical repair is required.


Why Buy Radiator Leak-Stop? 


  • Seals the cooling system and eliminates leaks through gaskets, clamps, small cracks in the radiator, cylinder head gaskets, from the water pump and from the cylinder block itself. 
  • Possesses excellent anti-corrosion properties, neutralizes corrosive acids;
  • Extends the life of the water pump;
  • Restores the lost elasticity and resilience of seals and gaskets, protects them from drying out, hardening, deformation and cracking, slowing down their ageing and thereby extending their service life.
