Antifreeze – general information
For gas station of the cooling system the antifreeze mix made in due proportions on the basis of ethylene glycol with soft water is usually used. Mix has to show resistance to freezing at temperatures to – 30 °C, and if necessary below, depending on climatic zone of an arrangement of the region of operation of the car. Except frost resistance, antifreeze gives to mix anticorrosive properties and raises a point of its boiling.
Depletion and washing of the cooling system have to be made according to the schedule of routine maintenance of the car (see the Head Nastroyki and routine maintenance of the car). Use of cooling liquid during longer term is fraught with different damages of system, development of corrosion and scaling. If tap water in the region where the car is operated, is "rigid", i.e. differs in the increased content of mineral salts, for formation of cooling liquid it is necessary to use the distilled or rain water.
Before adding cooling liquid in system, check reliability of fastening of hoses of the last on the unions – antifreeze has high fluidity and is capable to give leaks through the slightest thinnesses. During normal operation of the engine cooling liquid is not spent therefore noticeable falling of its level is a sign of development of external leaks which reason has to be immediately found out and eliminated.
The exact composition of cooling liquid is defined by specific climatic conditions. At the same time the content of antifreeze in mix should not be lower than 50% and rise higher than 70% – address the card of composition of cooling liquid which is usually applied on the label of a container. Areometers for determination of the specific weight (density) of cooling liquid can be bought practically in any shop of automobile accessories. Try to use only the antifreeze grades recommended by manufacturers of the car (see Specifications).
