3.2. General information on antifreeze

Do not allow antifreeze hit on open sites of a body and the painted surfaces of the car. Casually got drops immediately wash away a plentiful quantity of water. Antifreeze is the extremely poisonous liquid which hit in an organism even in insignificant quantities can have a lethal outcome. Never leave antifreeze in open container or spilled on a garage floor - its sweetish smell can easily involve children and animals. Eliminate leaks in cooling system immediately as soon as will notice them.

Filling of system of cooling should be made by antifreeze solution on base этиленгликоля in water in the ratio 40:60 which will provide its stability to freezing at temperatures approximately to-27 ° with Page Besides, antifreeze raises a cooler boiling point, and also (if it high quality) provides corrosion counteraction.

The system of cooling should be merged, washed out and again to fill through certain periods (see. Head Routine maintenance of the car). The old or polluted solution of antifreeze quite can will serve as the reason of serious damages, and also to stimulate formation of a rust and a scum in system. Whenever possible try to use with antifreeze distilled, or pure rain water. Water from the crane can approach, if it not too "rigid".

Before a flood of antifreeze check a condition of all shlangovy connections since antifreeze has property to filter through the most insignificant thinnesses. In normal conditions the engine does not spend a cooler therefore if its level falls, it is necessary to find out the reason of it and to eliminate it.

The mix of antifreeze should be made in the correct proportion; addition of too large amount of antifreeze reduces system effectiveness of cooling. If necessary before filling it is possible to consult the map rules of drawing up of an okhladitelny mix on container with antifreeze. Necessary for cooler check the areometer can be got in shop of auto parts. Try to use the antifreezes recommended by the producer of the car.
