Protect your engine from the dangers of coolant loss with LIQUI MOLY Radiator Stop Leak (Kühlerdichter). This specialized additive is designed to provide an immediate and reliable seal for minor leaks and hairline cracks in the cooling system, preventing engine damage caused by overheating.
Brand: LIQUI MOLY
Product Name: Radiator Stop Leak / Kühlerdichter
Volume: 150 ml
Part Number: 3330
Origin: Made in Germany
Compatibility: Suitable for all water-cooled engines in gasoline and diesel vehicles.
Mix Ratio: One 150ml can is sufficient for up to 10 liters of coolant.
This product is a cost-effective alternative to immediate mechanical repairs for minor cooling system failures.
Seals Leaks: Effectively plugs small leaks caused by stone impacts, porous spots, and hairline cracks in the radiator or the entire cooling circuit.
Immediate Action: Works quickly while the vehicle is running to stop existing leaks and prevent further loss of coolant.
Complete System Safety: Compatible with all standard coolants and antifreeze (such as RAF 12+), and does not harm water pumps, plastic components, or heating circuits.
Preventative Protection: Can be used to safeguard against potential future leaks in aging cooling systems.
Radiator Stop Leak contains microscopic polymer particles that remain suspended in the coolant until they encounter a leak.
Pressure Activation: When the coolant escapes through a crack, the sudden drop in pressure and exposure to outside air causes the polymers to react.
Fiber-Reinforced Seal: The particles bond together at the site of the leak, forming a durable, fiber-reinforced plug that stops the escape of fluid.
No Clogging: The formula is designed to only react at leak points, ensuring it does not clog the narrow passages within the radiator core or heater matrix.
Preparation: Shake the can well before use.
Add: Pour the contents into the cooling system when the engine is at operating temperature.
Run: Start the engine and let it run for at least 10 minutes to allow the product to circulate and seal the leaks.
Note: Always ensure the engine has cooled sufficiently before opening the radiator or expansion tank cap to avoid burns.
