Purpose and Specifications

The LIQUI MOLY 3043 Motorbike Radiator Stop Leak is a 125 ml sealant designed to permanently fix hairline cracks and small leaks in your motorcycle's cooling system. It works reliably on aluminum and plastic radiators, with no harmful side effects, and mixes safely with all standard coolants and antifreezes.

This premium product treats up to 5 liters of coolant, keeping your engine cool during rides in temperatures from -30°C to over 120°C. It's perfect for quick fixes that last tens of thousands of kilometers without needing replacement, as long as your cooling system stays maintained.

• Permanently seals tiny leaks to prevent overheating
• Shake well, add to cold system, drive 10 minutes for activation
• Shelf life of 4 years when stored frost-free

When to Use / Replace?

Use it when you spot coolant drips, low levels, or warning lights from minor leaks. Apply preventively after cooling system repairs. No routine replacement needed - one treatment holds for 50,000+ km or 3-5 years under normal riding. Flush and retreat only if major issues arise or after 5 years.
