Antifreeze LL 15 is a premium, orange-coloured Long Life antifreeze for which a patented, silicate-free technology based upon caroxyl acids, has been used. With this technology, Antifreeze LL 15 provides longer lasting protection against corrosion than standard antifreeze, so that vulnerable parts such as radiators, water pumps and seals will have a longer service life. Powerful corrosion inhibitors prevent sludge and deposits forming in the radiator, ensuring optimal cooling, even in the long term. Antifreeze LL 15 is specifically designed for use in engines/radiators made from light metals such as aluminium, magnesium or their alloys.


Antifreeze LL 15 is suitable for the cooling systems of the various models produced by the GM group (Opel/Saab/Vauxhall) that require a Long Life GM 19 40 650-grade coolant. By using powerful corrosion inhibitors, Antifreeze LL 15 is practically unaffected by ageing, giving it a much longer service life. Optimal results can only be achieved with 100% filling. Dilute with demineralised water to the recommended ratio before use.
