Mannol G12 coolant is a ready to use solution formulated with carboxylated organic acid technology for year round engine cooling protection. It delivers reliable corrosion resistance for metals and alloys such as aluminium cast iron copper and steel. The coolant maintains strong thermal stability and efficient heat transfer while preventing foam formation and deposit buildup. It is safe for use with all types of rubber and plastic components and resists hard water effects ensuring long lasting inhibitor performance. Free from silicates nitrates phosphates and amines it supports extended service life up to 250000 km for passenger cars 500000 km for commercial vehicles and up to six years for stationary engines. Ideal for high load and turbocharged systems it ensures consistent temperature control and reliable cooling system performance.
