Special additive in the coolant MANNOL 9966 Radiator Leak Stop – sealant for cooling systems of internal combustion engines (ICE) and cabin heating systems. Suitable for any ICE with liquid cooling, with radiators made of any materials (aluminum, copper, plastic, composite, etc.). It is a mixture of metal polymers and special fibers and is designed to eliminate leaks in the system.

Product properties:
- Compatible with any coolant, as well as with water;
- Seals the cooling system and eliminates leaks through gaskets, clamps, small cracks in the radiator, cylinder head seals, from the water pump, and from the cylinder block itself. Prevents future leaks;
- Hardens only at leak sites, without clogging radiator tubes. Once hardened, it withstands vibration, temperature fluctuations, does not wash out, and does not dissolve;
- Especially recommended for sealing microcracks and microleaks, the location of which is hard to determine, but which cause a drop in coolant level;
- Absolutely neutral to all structural materials (metals and alloys, plastic and rubber parts). Restores lost elasticity and pliability of seals and gaskets, prevents drying, hardening, deformation, and cracking, slowing their aging, and thus extending their service life;
- Possesses excellent anti-corrosion properties, neutralizes corrosion-causing acids;
- Extends the service life of the water pump;
- Can be used for preventive purposes to prevent leaks, as well as to prevent the aging and wear process of seals and gaskets, and in general, for preventing cooling system failures.

Application: Start the engine at idle and let it warm up to operating temperature, turn on the cabin heating. Shake the bottle's contents thoroughly and pour it into the cooling system expansion tank (or into the radiator). The contents of one 325 ml bottle are sufficient for a system of 12 liters. Allow the engine to run for 10 minutes at idle. If leaks are not eliminated within 3 days – mechanical repair is required.
