1.37. Cooling system


At plant the system refuels the cooling liquid which is intended for long-term work and not demanding replacement. Liquid consists of water from 40 %-y (for the V8 engine – 50 %) add G 011 A8C additives. This mix not only provides necessary frost resistance to–25 ° With (for the V8 engine – 35 ° C), but also protects first of all light-alloy components from corrosion. Besides, adjournment of a scum is prevented and considerably the liquid boiling point raises. Therefore even in a warm season or in the countries with warm climate it is impossible to reduce concentration of a mix water addition. The share of an additive should be not less than 40 % (for the V8 engine – 50 %).

In need of higher degree of frost resistance it is possible to increase G 011 A8C share, but only to 60 % or 54 % for the V8 engine (frost resistance approximately to–40 ° C) as further accumulation of concentration conducts to decrease in frost resistance and deterioration of cooling effect. Exported to the countries with a frigid climate (for example, Sweden, Norway, Finland) cars already at plant refuel antifreeze at the rate on work at temperature to–35 ° Page. As an additive to cooling liquid apply (with instruction observance on packing) only G 011 A8C or an additive according to the TL-WV 774 specification C. These additives can be received at the Audi enterprise. Other additives to liquid can essentially break its properties and first of all effect of corrosion protection. Resulting corrosion damages can cause leakage of cooling liquid and to lead subsequently to serious damages of the engine.

Control of level of cooling liquid

The broad tank is in the left part of podkapotny space.

When falling level of liquid the control lamp lights up. Despite it, it is recommended to be checked from time to time. Authentically to check level it is possible only at the idle engine.

At the cold engine level should be between labels of "max" and tank "min"; on heated-up level can exceed "max" label slightly.

Leakage of cooling liquid

Leakage of cooling liquid allows to assume first of all existence not density in cooling system. In this case urgently check system at the Audi enterprise. It is impossible to be limited only to a liquid dolivaniye. At undisturbed tightness leak can arise only in that case when cooling liquid begins to boil because of an overheat and replacement from cooling system.

Dolivaniye of cooling liquid

At first muffle the engine and let's to it cool down. Then cover a stopper of a broad tank with a fabric and carefully unscrew it on one turn to the left, having pitted thus superfluous pressure. After that completely turn off a stopper.


The system of cooling is under pressure!

If, on a chrezvychaynost of circumstances, it is necessary to add only water, at the first possibility restore standard concentration of solution, having added the component put on the instruction.

At considerable leakage of cooling liquid, it, in order to avoid engine damages, it is possible to add only after it will cool down.

Do not pour liquid above "max" label: excess of liquid at its heating is forced out from system through a safety valve in a stopper of a broad tank!

Densely twist a stopper.

Fan of system of cooling

On 4-and 6-cylinder engines the fan works from the electric drive operated by a thermoswitch depending on temperature of cooling liquid.

On 5-and 8-cylinder engines the drive of the fan is carried out through ridge maple a belt from the engine. The fan is equipped with the vyazkostny coupling regulating frequency of its rotation depending on temperature. The additional electrodriving fan with step regulation of turns is automatically connected in the course of operation of the engine, depending on temperature of cooling liquid.
