MANNOL 9966 Radiator Leak Stop for Cooling System of Internal Combustion Engines 325 ML

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 fibers 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 liter system. Let the engine idle for 10 minutes. If the leaks are not eliminated within 3 days, mechanical repair is required.
