A diluted on ethylene glycol/glycerine based coolant for use in engines. It employs Hybrid Organic Acid Technology (HOAT) inhibitor, is nitrite, amine, phosphate (NAP) and borate free. It contains some silicate additives which gives a fast healing aluminium protection. This technology provides superior and permanent protection to all components of the cooling system and a life span of 4 - 6 years or 250.000 km for passenger cars and 500.000 km for professional applications. Ready to use solution.Formulated for long-term use in all engines especially those constructed from aluminium, cast iron and magnesium alloys. Not the best choice for older cooling systems that have copper/brass radiators and heater cores, especially not for the lead solder used in them.Suitable for cooling circuits of the open or closed type (vehicles and heating) with a protection against freezing until -36°C. This solution is ready to use and can be used during the whole year.
