As part of ongoing technical development, the previous anticorrosion/antifreeze agent G48® (green/blue color) is replaced by the anticorrosion/antifreeze agent G40® (red color).
The anticorrosion/antifreeze agent G40® exhibits the following advantages compared with G48® :
Lower deposits in engine cooling system,
Improved heat dissipation,
Higher environmental compatibility, because there are no ecologically harmful constituents containing borax.
The anticorrosion/antifreeze agents G40® and G48® must not be mixed. Any mixing would result in a rust-brown discoloration. This discoloration may result in complaints.
Before refilling, it is necessary to ascertain which anticorrosion/antifreeze agent was used to fill the vehicle. Each anticorrosion/antifreeze agent can be determined by the color:
Red color - anticorrosion/antifreeze agent G40®,
Green/blue color - anticorrosion/antifreeze agent G48®.
Anticorrosion/antifreeze agent G40® must be replaced after 3 years.
The conversion of series to the new coolant took place in April 2013:
MODEL 405.05 as of VIN end no. 233480,
MODEL 405.10/12/20/22 as of VIN end no. 233465,
MODEL 437.42/43 as of VIN end no. 233460,
MODEL 437.46 as of VIN end no. 233468.
