KFS 18 – the new generation of radiator protection from LIQUI MOLY
What makes our KFS 18 so special?
Greater vehicle coverage – ideal for many modern vehicles, including the latest BMW models.
Green color as a distinguishing feature – immediately recognizable.
State-of-the-art technology – with Si-OAT technology, an innovative combination of silicate and organic additives. This hybrid formula ensures: excellent anti-corrosion, very good thermal conductivity and a long engine service life
Strong protection – without compromise
Our KFS 18 contains no amines, borates or nitrites – i.e. is free of substances that are no longer up to date for environmental or technical reasons. Nevertheless, the product offers optimum protection against frost, overheating and corrosion as well as a high-quality protective effect for light alloy engines, especially at high temperatures.
Who is the KFS 18 suitable for?
Whether professional workshop or ambitious hobby mechanic – KFS 18 is suitable for cars (gasoline, diesel, hybrid, electric), commercial vehicles, motorcycles, buses, construction machines and more. Wherever modern engine technology is used and cooling system protection of this quality is required.
Our expertise in cooling systems
We not only offer a wide range of radiator antifreeze products, but also cover related areas. An example of this is our Radiator Cleaner, which is used for thorough preparation when the coolant is due to be changed. In turn, our Radiator Stop Leak ensures that leaks in the cooling system are immediately and completely sealed through dispersion in the hairline cracks, thus protecting the combustion chamber from damage caused by coolant ingress. A helpful feature: it can be used preventively and is compatible with all common coolant enhancers and antifreezes.
