Overheating is one of the most common causes of engine failure. LIQUI MOLY Radiator Cleaner (Kühlerreiniger) is a concentrated solution designed to remove lime, scale, and oil deposits from your vehicle’s entire cooling system, restoring its ability to regulate temperature effectively.
Brand: LIQUI MOLY
Product Name: Radiator Cleaner / Kühlerreiniger
Volume: 300 ml
Part Number: 1804 / 3320
Origin: Made in Germany
Compatibility: Suitable for all cooling water and heating systems in gasoline and diesel vehicles.
Mix Ratio: One 300ml can is sufficient for up to 10 liters of coolant.
This cleaner is a vital part of preventative maintenance, especially before adding new coolant.
Dissolves Deposits: Effectively breaks down lime, scale, and sludge that build up in the radiator, hoses, and engine block.
Removes Oil: Contains specialized dispersants to clear out oily residues caused by faulty gaskets or seals.
Restores Heat Transfer: By cleaning the internal surfaces, it ensures the coolant can absorb and release heat at maximum efficiency.
Safe for Materials: Does not contain aggressive acids or alkalis; it is completely safe for rubber hoses, plastics, and metals like aluminum and light alloys.
Over time, minerals in the coolant and heat cycles create a “crust” inside your cooling system. This acts as an insulator, trapping heat inside the engine.
Chemical Suspension: The cleaner breaks these mineral deposits into tiny particles and keeps them suspended in the liquid so they can be flushed out.
Neutralization: It neutralizes acids that can lead to internal corrosion and cavitation.
Optimization: A clean radiator allows the thermostat and water pump to function correctly, preventing the cooling fan from running excessively.
Add: Pour the 300ml can into the cooling system through the radiator or expansion tank.
Run: Start the engine and turn the vehicle’s heater to the “maximum” setting. Let the engine run at operating temperature for 10 to 30 minutes.
Drain & Flush: Turn off the engine, let it cool slightly, and drain the old coolant. Flush the system thoroughly with water until it runs clear.
Refill: Fill the system with fresh coolant (such as RAF 12+) according to the manufacturer’s specifications.
