LISOL® Protect C11 – Economic Antifreeze blue

LISOL Protect C11 – Economic Antifreeze and Corrosion Protection Concentrate for Vehicle Cooling Systems

LISOL Protect C11 is an economic radiator corrosion inhibitor and antifreeze concentrate for water-cooled combustion engines. The product contains no nitrites, amines or phosphates and ensures reliable, year-round frost and corrosion protection.
It has no negative effect on coolant hoses or cylinder head gaskets and is suitable for engines made of cast iron, aluminum or mixed constructions.

When mixed with the proper amount of water, Protect C11 functions as an effective cooling and heat transfer fluid. It is particularly recommended for light-alloy engines requiring enhanced aluminum protection at higher temperatures. A concentration of 50 vol.% is recommended for year-round operation.
