As part of ongoing technical development, the coolant was changed in the above models in April 2014.
The previous anti-corrosion agent/antifreeze G48® (green/blue color) has been replaced in series production with anti-corrosion agent/antifreeze G40® (violet color).
The vehicle identification end numbers and the dates for the coolant change are listed below:
- Model 447.### ## as of 001495
- Model 636.### ## as of 045979
- MODEL 639.### ## as of 888455
- Model 900.### ## as of 002835
- Model 906 as of production period 28.07.2014
The anti-corrosion agent/antifreeze G40® may be used for those models that were filled at the factory with G48® (green/blue color) up until the series production changeover. The two anti-corrosion agents/antifreezes G48® (green/blue color) and G40® (violet color) can be mixed with no technical restrictions. Further information about the two anti-corrosion agents/antifreezes G48® and G40® with regard to miscibility and use in Europe is available in Service Information SI20.00-Z-0017A .
Each anticorrosion/antifreeze agent can be determined by the color.
- Violet color: Anti-corrosion agent/antifreeze G40®
- Green/blue color: Anticorrosion/antifreeze agent G48®
