1.3.7. System of cooling of the engine

GENERAL INFORMATION

The system of cooling of the engine is filled at manufacturer with cooling liquid of long action which it is not necessary to replace.

Cooling liquid consists for 60 % of water and for 40 % from a low-temperature concentrate of G12 (low-temperature structure on a basis этиленгликоля with anticorrosive additives). This mix not only provides operability of system of cooling of the engine to temperature - 25°С, but also protects details from corrosion, first of all details from easy alloys. Besides, this mix prevents scaling and essentially increases temperature of boiling of cooling liquid.

Therefore the maintenance of a low-temperature concentrate also in a warm season and in the countries with warm climate should not be lowered by a way of use of water for a dolivka. The share of a low-temperature concentrate should be not less than 40 %.

If in the conditions of severe climate higher frost resistance of cooling liquid is necessary, it is possible to raise a share of a concentrate of G12, but only to 60 % (the temperature of freezing of cooling liquid in this case will make near - 40°С) as at a bigger share of a low-temperature concentrate the temperature of freezing of cooling liquid will start to raise, and, besides, indicators of a thermal capacity and heat conductivity of cooling liquid will worsen.

As a low-temperature concentrate it is necessary to use only our structure of G12 or a concentrate with the TL-VW 774 specification D (pay attention to an inscription on container).

Other concentrates can be substantially aggressive, first of all, in relation to corrosion-resistant coatings.

The corrosion which has arisen because of these concentrates of metal details can lead to leakage of cooling liquid, and it in turn – to serious damages of the engine.

As a low-temperature concentrate it is necessary to use only our structure of G12.

At a dolivka of cooling liquid consider, please, the following: by no means it is impossible to mix G12 structure with other low-temperature concentrates (as well with G11 structure).

You can determine G12 structure by red color of cooling liquid in a broad tank. If cooling liquid in a broad tank of brown color, means, the structure of G12 is mixed with other low-temperature concentrate! In this case it is necessary to replace cooling liquid surely!

Otherwise there can be serious violations in operation of the engine!
