Plums

Open a cover of a broad tank of system of cooling.

ATTENTION When opening a broad tank it can leave hot steam. In order to avoid injuries of eyes and an oshparivaniye put on goggles and clothes. Cover a tank cover with rags and accurately open it.

Remove a noise isolation.

Unscrew a carving stopper, the shooter in drawing 2.243 of a radiator.

NOTE Observe rules of utilization of cooling liquid.

In addition, for plum of cooling liquid from the engine, disconnect hoses of cooling liquid from the thermostat case (fig. 2.244) .

Gulf

As a concentrate of cooling liquid use only means of G 12 on norm of TL – VW of 774 F is allowed. Characteristic sign: lilac color

G 12 and concentrates with a mark «according to TL – VW of 774 F» interfere with freezing of cooling liquid, formation of corrosion and a scum. Besides, they increase temperature of boiling of cooling liquid. Therefore during the whole year in system of cooling the anticorrosive concentrate should work interfering freezing and formation of corrosion.

Especially in the countries with tropical climate at high loads of the engine cooling liquid with the increased temperature of boiling reliably protects the engine at operation.

The temperature of freezing of cooling liquid should make not less than-25 °C (in the countries with the Arctic climate – not less than-35 °C).

It is forbidden to reduce also a share of a concentrate in cooling liquid in a warm season or at operation in the countries with warm climate, adding in cooling system water. The share of a concentrate should make not less than 40 %.

If because of climatic conditions the temperature of freezing has to be lowered, it is possible to increase a share of a concentrate of G 12, but no more than to 60 % (the temperature of freezing will make in that case about-40 °C). At excess of this limit the freezing temperature will raise again, and the thermal capacity of cooling liquid, besides, will decrease.

At replacement of a radiator, the heat exchanger of a heater, GBTs or GBTs laying the reuse of the merged cooling liquid is forbidden.

For determination of temperature of freezing of cooling liquid it is recommended to use рефрактометр T10007.

NOTE The amount of filled-in cooling liquid can differ depending on a car complete set.

Recommended proportions of mixing

Works order

Establish hoses of system of cooling and to fix them.

To fasten the adapter for a tester of system of cooling of V.A.G 1274/8 on a broad tank.

Fill in cooling liquid by means of the adaptation for filling of system of cooling of VAS 6096.
