Testing the cooling liquid composition
Fig. 3-32:
The engine operating instructions contain a detailed description of how to prepare and test the cooling liquid composition. In case of imminent frost check that the factory-adjusted anti-freeze concentration is sufficient for the expected temperatures. Check the cooling liquid in the cooling system regularly to ensure that the water filter replacement interval resp. the DCA4 mixture is sufficiently concentrated to prevent corrosion under the corresponding operating conditions.
