Check the quality of the anti-freeze liquid

Model: BMW Serie 5 E39 - Years 1995-2003
Part: Antifreeze liquid

Antifreeze is a liquid additive used mainly for combustion engines, which is used to prevent a certain liquid, exposed to low temperatures, from solidifying with the necessary consequences. The best known antifreeze are for the engine coolant, for the fuel and for the washing liquid for the windows. The synthetic antifreeze has the function of lowering the solidification point of the liquid with which it is mixed due to the cryoscopic lowering phenomenon. In European countries, the percentage of "antifreeze" that constitutes (percentage present) the "coolant" varies from a minimum of 30% (30% antifreeze 70% demineralized water) up to a maximum of 60% (60% antifreeze 40 % demineralized water). Checking the quality of the liquid consists precisely in checking the mixing percentage using a hydrometer like the one shown in the video: insert the tube into the tray, take some liquid with the pump and check the positioning of the lancet.
