Seal micro-cracks and stop coolant leaks fast with this 250 ml Radiator Sealant Fluid. Specially formulated for vehicle cooling systems, it delivers effective, long-lasting protection by sealing hairline cracks and minor leaks before they become serious problems. Suitable for sealing the entire cooling system and heater core, it helps maintain optimal engine temperature and prolongs engine life.
This sealant not only addresses leaks in radiators and hoses but is also effective for freeze plugs, damaged engine blocks, cylinder heads, and water pump gaskets. Its advanced formula works without clogging or harming your system, ensuring smooth coolant flow for efficient heating and cooling.
Compatible with all types of coolant and antifreeze mixtures, this sealant is easy to use: just add 100 ml per 8 liters of coolant, so a 250 ml bottle treats up to 21 liters—making it ideal for passenger cars, trucks, and larger vehicles. For best results, check your cooling system's condition before use. On older vehicles, remove any limescale or sludge first for optimal performance.
Shake the bottle well before pouring directly into the radiator or through the expansion tank with the engine off. Top up coolant if necessary and securely close the system. Run the engine at idle for 15–25 minutes with the heater on, allowing the sealant to circulate and act. After the engine cools, check if leaks have stopped and top up coolant if needed.
Regular maintenance is essential for a reliable cooling system. This radiator sealant provides a dependable fix for small leaks, helping you avoid costly repairs and prolonging your engine’s performance and efficiency in all conditions.
