Service Information: Information On Using Coolant - SI20.00-Z-0017A

Engine All (4xWD, CAR, Light transporter, smart) 

We would like to inform you that the use of anti-corrosion agent/antifreeze G48® is prohibited in all service centers as of 17.12.2022.

The anti-corrosion agent/antifreeze G40® can be used here as a replacement. In future, the cooling circuits of all vehicles with manufacturing date up to and including 04/2014 may have anti-corrosion agent/antifreeze G40® added to them without restrictions.

The Arteco Freecor NRC coolant (fluorescent yellow) for engine development cooperations (e.g. in the Citan, X-Class, smart electric), will soon no longer be produced/marketed and it will be replaced by Arteco Freecor LPC (blue color). Both can be mixed without any technical restrictions.

Questions and answers 

• After 17.12.2022, can our service partners still add the anti-corrosion agent/antifreeze G48® to customer vehicles in their workshop as part of a new customer order to enable residual quantities to be used up?

  Yes, service centers may use up any residual quantities. For over-the-counter sales in the EU, always ensure that only commercial customers receive the product and that the necessary safety precautions are permanently guaranteed.

• The EU Regulation, however, does permit professional use (draining/filling) by the service centers or sales to independent workshops/commercial re-users. Why is this prohibited in this document?

  This is prohibited because we cannot ensure that they will properly and professionally used. To protect our customers, employees and the environment, we have removed the product from the product range.

• Is it OK to mix anti-corrosion agent/antifreeze G48® with anti-corrosion agent/antifreeze G40®?

  There are no technical limitations on mixability, i.e. G40® can be added in any quantity to cooling circuits filled with G48® without any need to replace the coolant, and without using any special procedure.

• Which color is produced when anti-corrosion agent/antifreeze G48® is mixed with anti-corrosion agent/antifreeze G40®?

  Depending on the mixing ratio between both products, the blue or mauve proportion will be increased.

If the mixture results in a rust-brown discoloration, this is not a quality problem.
