Coolant SP 15 is a premium, ready-to-use Long Life coolant (frost protection down to -38 °C) for which a patented, silicate-free technology based upon carboxyl acids, has been used. With this technology, Coolant SP 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. Coolant SP 15 is specifically designed for use in engines/radiators made from light metals such as aluminium, magnesium or their alloys.


Coolant SP 15 is a fluorescent orange, ready-to-use coolant for the cooling systems in the latest models from the GM group (Opel/Saab/Vauxhall) that require a Long Life coolant with the GM 19 40 650 quality. By using powerful corrosion inhibitors, Coolant SP 15 is practically unaffected by ageing, giving it a much longer service life than conventional coolants. Optimal results can only be achieved with 100% filling.
