Liqui Moly Radiator Antifreeze KFS 12+ – OAT Antifreeze for Boat Engines
No boat engine can tolerate frost or corrosion – especially not a modern high-performance aluminum engine. Liqui Moly KFS 12+ reliably protects your cooling system from freezing, overheating, and corrosion. Developed specifically for the demands of marine drives, it is approved by leading boat engine manufacturers such as Volvo Penta, Yanmar, Mercruiser, and Vetus.
Tip: Before filling, completely drain the cooling system and flush thoroughly with water. For the mixing ratio (recommended 50:50), use distilled water – tap water only if water hardness is a maximum of 3.566 mmol/l. Store undiluted only. You can find the right antifreeze for your specific engine using the Liqui Moly Oil Guide.
