21. Be sure to replace the antifreeze at the indicated intervals. This is necessary not only to preserve the properties of antifreeze, but also to prevent corrosion.
22. Always use ethylene glycol based antifreeze. The amount of antifreeze and temperature limits are specified in the Specifications. To get the recommended 50% concentration. 3 liters of antifreeze must be mixed with 3 liters of clean soft water; this amount will be enough to fill the system, but it is better to cook more so that there is left for later refueling.
23. Before adding antifreeze, the liquid from the cooling system must be completely drained, the system preferably flushed, and the condition and reliability of all hoses must be checked.
24. After filling with antifreeze, stick a label on the expansion tank indicating the type and concentration of antifreeze used, as well as the date it was filled. All subsequent top-ups must use the same type of antifreeze at the strength indicated on the label.
25. Do not use antifreeze in the windshield washer system, as it may damage the car's paintwork.
