Liqui Moly | Radiator Stop Leak Cooling System Sealer (250ml)

Defend your engine against critical coolant loss and severe thermal damage with the advanced Liqui Moly Radiator Stop Leak. Engineered by Germany’s premier automotive chemical specialist Liqui Moly, this professional-grade cooling system sealer provides a fast, highly dependable remedy for unexpected radiator failures. Over time, hair-thin cracks, porous solder connections, or micro-punctures from road debris can cause steady coolant loss. Liqui Moly’s advanced formula circulates naturally with your active antifreeze and seals these micro-leaks instantly upon contact with external oxygen, forming a durable seal that preserves fluid levels without creating internal flow restrictions.

2. Shake the container thoroughly and pour the entire 250ml bottle of Liqui Moly Radiator Stop Leak directly into the cooling reservoir.

3. Switch the vehicle's interior cabin heater control to maximum hot to ensure the fluid circulates through all secondary heating cores.

4. Start the engine and let the vehicle idle for at least 10 minutes or take it for a short drive to allow the chemical sealant to fully engage and secure the leak sites.

Important Note:

To prevent severe personal injuries from pressurized boiling steam, never attempt to open the system while hot. This concentrated 250ml bottle is perfectly measured to treat passenger car cooling networks.
