System of cooling of the engine

Antifreeze - the general data

 Do not suppose antifreeze hit on open sites of a body and the painted surfaces of the car. Casually got splashes immediately wash off a plentiful quantity of water. Remember that antifreeze is extremely a toxic liquid and its hit in an organism even in small amounts is fraught with the most serious consequences (up to a lethal outcome). Never leave antifreeze stored in leaky closed container and immediately collect cooling liquid spilt on a floor. Remember that the sweetish smell of antifreeze can draw to itself attention of children and animals. About ways recyclings of the fulfilled cooling liquid consult at any station of car-care centre. In many regions of the world special points on any reception of working off are equipped. At all do not merge an old cooling liquid in the water drain and on the earth!


 Recently nontoxical grades of antifreeze are developed, however they also are subject to recycling in the organised order.


For refuelling of system of cooling the mix of antifreeze made in due proportions on base этиленгликоля with soft water is usually used. The mix should show stability to freezing at temperatures to-30°S, and if necessary and more low, depending on a climatic belt of an arrangement of region of operation of the car. Except frost resistance, antifreeze gives mixes anticorrosive properties and raises a point of its boiling.

Опорожнение and washing of system of cooling should be made according to the schedule of routine maintenance of the car (Routine maintenance see the Head). Use of a cooling liquid during longer term is fraught with any damages of system, development of corrosion and a scaling. If tap water in region where the car is maintained, is "rigid", i.e. differs the raised maintenance of mineral salts, for formation of a cooling liquid it is necessary to use the distilled or rain water.

Before to add cooling liquid in system check up reliability of fastening of hoses of last on the unions - antifreeze possesses high fluidity and is capable to give leaks through the slightest thinnesses. During normal operation of the engine the cooling liquid is not spent, therefore appreciable falling of its level is a sign of development of the external leaks which reason should be immediately found out and eliminated.

The exact structure of a cooling liquid is defined by concrete environmental conditions. Thus the antifreeze maintenance in a mix should not be below 50 % and not exceed 70 % - address to a card of structure of a cooling liquid which is usually put on a container label. Ареометры for definition of relative density (density) of a cooling liquid it is possible to get practically in any shop of automobile accessories. Try to use only recommended by manufacturers of the car of a grade of antifreeze (Specifications see).
