Liqui Moly Motorbike Radiator Stop Leak is a high-quality coolant system sealant designed to quickly and reliably close hairline cracks and small leaks within the cooling circuit. Formulated as a stabilised solids dispersion, it circulates through the system to seal problem areas without causing blockages or negative side effects. Ideal for preventive use after cooling system repairs or when early signs of coolant loss appear, this product is fully compatible with standard antifreeze and coolant conditioners. Safe for use in aluminium radiators, it ensures long-term leakage protection and improved cooling system reliability.
