LIQUI MOLY Radiator Stop Leak, part number 20132, 250 ml, is a German-engineered cooling-system additive from LIQUI MOLY. As an aftermarket radiator stop-leak, it is designed to seal small leaks from the inside of radiators and cooling passages, helping prevent coolant loss and overheating while protecting against corrosion. The formula is compatible with most conventional cooling systems and is suitable for metals used in modern radiators, including aluminum.

Over time, leaks arise from aging seals, corrosion, and vibration; minor cracks and porosity can develop in the core. When added to the coolant, the liquid circulates to form a flexible seal, restoring integrity and maintaining proper flow. LIQUI MOLY's 20132 reflects the brand's engineering heritage and reliability, delivering a practical, aftermarket solution for maintaining coolant system performance.
