This advanced cooling system sealant is designed to quickly and safely stop leaks in liquid-cooled engines. It effectively seals micro-cracks and small leaks in radiators, hoses, gaskets, water pumps, and cylinder head areas without clogging radiator channels. Compatible with all types of coolants and radiator materials, it cures only at leak points, withstands vibration and temperature changes, and provides long-lasting protection. In addition to stopping leaks, it helps prevent corrosion, protects seals from aging, and supports reliable cooling system performance.
