A special coolant additive and sealant for internal combustion engine (ICE) cooling systems and cabin heating systems. Suitable for all liquid-cooled ICEs, with radiators made of any material (aluminum, copper, plastic, composite, etc.). It is a blend of metal polymers and special fibers and is designed to seal leaks in the system.

Product Properties:
– Compatible with any coolant, including water;
– Seals the cooling system and eliminates leaks through gaskets, clamps, minor cracks in the radiator, cylinder head seals, water pump, and the cylinder block itself. Prevents future leaks;
– Hardens only at the leak site, without clogging radiator pipes. Once cured, withstands vibration and temperature changes, and is not washed out or dissolved.

– Particularly recommended for sealing microcracks and micro-leaks that are difficult to locate but cause coolant levels to drop;
– Completely neutral to all structural materials (metals and alloys, plastic and rubber parts). Restores lost elasticity and resilience to seals and gaskets, protects them from drying out, hardening, deformation, and cracking, slowing their aging and thereby extending their service life;
– Possesses excellent anti-corrosion properties, neutralizing corrosive acids;
– Extends the life of the water pump;

– Can be used to prevent leaks, as well as to prevent the aging and wear of seals and gaskets, and to generally prevent cooling system failures.

Application: Start the engine at idle and allow it to warm up to operating temperature. Turn on the cabin heating. Shake the contents of the bottle thoroughly and pour it into the cooling system's expansion tank (or radiator). One 325 ml bottle is sufficient for a 12-liter system. Let the engine idle for 10 minutes. If the leaks persist within 3 days, a mechanical repair will be required.
