Draining coolant Bay
Draining Open the expansion tank of the cooling system.
ATTENTION Upon opening of the expansion tank can stand the hot steam, wrap a cloth cover and open the tank. |
Remove noise insulation. Remove the bracket of the lower coolant hose and remove the hose from the quick connector choke the radiator. Additionally, to drain the coolant from the engine, disconnect the coolant hose from the oil cooler.
NOTE Observe regulations for disposal |
Bay Freezing coolant should be at least -25 ?� C (in countries with arctic climates - not less than -35 ?� C).
NOTE As the concentrate is allowed to use only G 12 - the norm TL VW 774 F. A characteristic feature - lilac G 12 lilac (at a rate of TL VW 774 F) is allowed to be mixed with the concentrate previously used G 12 - red. G 12 and concentrates with a mark "according to the VW TL 774 F?� prevent freezing of the coolant, and corrosion and scale formation. Additionally they increase the boiling point of the coolant. Therefore, throughout the year in the cooling system has to work to resist freezing and corrosion anti-rust concentrate. |
It is also prohibited to reduce the proportion of concentrate in the coolant in the warm season, or when operating in countries with warm climates, adding to the cooling system water. The proportion of the concentrate should be at least 40%. If, due to climatic conditions freezing temperature must be reduced, it is possible to increase the share of concentrate G 12, but not more than 60% (the freezing point in such a case would be about -40 ?� C). Beyond this limit freezing temperature to rise again and, moreover, decrease the heat capacity of the coolant. When replacing the radiator, heater exchanger, cylinder head or cylinder head gasket reuse drain the coolant is prohibited.

|
Install the lower coolant hose and secure the bracket (Fig. 2.334). Connect the coolant hoses to the oil cooler. Install screen proofing. Attach the adapter to the expansion tank. Fill in cooling liquid in the cooling circuit by means of a device for filling the cooling system.
