NIGRIN Kühlerdichter – Coolant Sealant for Vehicle Cooling Systems
The NIGRIN Kühlerdichter is a ready-to-use coolant sealant designed to prevent and repair small leaks in vehicle cooling systems. It provides immediate protection against coolant loss and helps maintain the integrity of the entire cooling circuit.
Seals minor leaks in hoses, radiators, and water pumps without the need for a full system flush
0.25 l bottle covers one standard cooling system fill
Corrosion protection keeps metal components safe from electrolytic degradation
Operates reliably from 0 °C upwards, suitable for year-round use
Das zeichnet NIGRIN Kühlerdichter aus
Unlike temporary stop-leak additives that can clog narrow passages, this formula is engineered for compatibility with all standard coolant types and cooling system materials, including aluminium, copper, and rubber seals.
Ideal für...
Vehicle owners who notice early signs of coolant loss — such as occasional drops in the reservoir level or faint traces of coolant under the car — and want to address the issue before it escalates into a costly cooling system repair.
Anwendung von NIGRIN Kühlerdichter
Shake the bottle well before use. Pour the entire 0.25 l contents into the coolant expansion tank when the engine is cold. Start the engine and let it run for several minutes with the heater set to maximum to circulate the sealant through the system. Top up the coolant level if necessary after the engine has cooled down.
