Check of level of cooling liquid Shooters in drawings showed the provision of marks a move and min the level of cooling liquid. At the left for 4-and 5-cylinder engines, on the right for the 6-cylinder engine.
Continuous check Despite existence of the indicator of temperature of the cooling liquid/level of cooling liquid, you should not rely only on it, and from time to time to check liquid level in a broad tank in a motor compartment:
Addition of cooling liquid Noticeable loss of cooling liquid is a sign of malfunction or breakage. Cooling liquid is not spent, and in the closed cooling system it also cannot evaporate. A little cooling liquid it can be squeezed out to a cover only at an engine overheat. At continuous loss of cooling liquid it is necessary to check the cooling system for tightness according to the scheme described below in this chapter. If the carving cover of a broad tank has to be opened at the hot engine, danger of a burn is great – therefore it is necessary to work with care:
Cooling liquid In the cooling system not clear water, but mix from the antifreeze including the additives protecting from freezing and corrosion, and the distilled water circulates. Therefore it is better to speak about cooling liquid or the cooling means. The proportion of mixing makes for the European conditions 2:3, for the northern countries 1:1.
Same important as protection against freezing, is protection against corrosion. It prevents emergence in the cooling system of a scum, rust and other products of corrosion. Therefore the cooling means poured in a workshop with protection against corrosion does not need to be merged in the spring, and it is necessary to leave all the year round in the cooling system. In masterful Audis own security measure from freezing of "G 11 V8 B" is applied. The manufacturer allows also application of other brands carrying designation "according to TL VW 774 B". |
