Wurth Sealant is a reliable additive, designed for the permanent repair of leaks in older cooling systems.

• Permanent Sealing: Permanently seals capillary cracks and micro-leaks (usually in the radiator, engine block, or cylinder head).
• Engine Protection: Prevents coolant loss, thus protecting the engine from overheating and serious damage.
• Safe for Components: Does not negatively affect the radiator's construction materials, nor harm rubber or plastic components (e.g., hoses).
• Special Formula: Designed for engines with unfiltered cooling systems (usually older models) and should not be used in modern systems with contamination filters, as it may clog them.
• Dosage: One 300 ml container is sufficient for 10 liters of coolant.

Instructions for Use:

• Shake the bottle well before use.
• Add the contents of the bottle to the warm cooling system.
• Open the heating valves (if present) and let the engine run for at least 10 minutes.
• Check the coolant level again and top up if necessary.
