t  Anti-freezing G12 may only be used in accordance with standard TL -VW 774 D-. It is identified by the red color.
t  Never mix G12 with other anti-freezing additives.
t  If fluid in container is brown, that indicates it has been mixed with other anti-freezing. In that case, replace all the cooling fluid.
t  G12 and anti-freezing additives with the ”in accordance with TL -VW 774- D” indication prevent damages due to corrosion, freezing or mould formation, increasing even more cooling fluid boiling temperature. For these reasons, cooling system must always have the prescribed mix of anti-freezing and anti-corrosion products.
t  Especially in tropical countries, anti-freezing helps, due to the high boiling temperature it provides, to ensure operation safety when engine is submitted to heavy duty operation.
t  Anti-freezing protection must be ensured until nearly -25 °C (in arctic climate countries, until nearly -35 °C).
t  Cooling fluid concentration must not be reduced adding water during hot seasons in hot countries. Anti-freezing proportion must be, at least, 40%.
t  If the climate makes necessary more anti-freezing protection, G12 percentage may be increased, but only until 60% (anti-freezing protection up to -40 °C). The higher protection lowers cooling capacity and anti-freezing protection.
t  To determine anti-freezing protection density, it is recommendable to use Refractometer -T10007-.
t  In case of replacement of radiator, heat exchanger, head or head joint, used cooling fluid may not be reused.
