2. During maintenance, the condition of all hoses in the system must also be checked (see chapter 1). Defective components must be replaced (see Section 4).
3. Do not forget about the precautions that must be observed when servicing the cooling system (see section 2). The direct execution of maintenance procedures should be started only after the engine has completely cooled down, i.e. at least a few hours after the end of the trip.
Caution: Make sure that no coolant gets on the toothed belt or multi-ribbed belt when working with coolant! The glycol in the coolant can damage the toothed belt fabric to such an extent that the belt breaks after some time of operation, which in turn can lead to severe engine damage!
Emptying
4. On models of the corresponding configuration, it is necessary to turn off or set the air conditioner to ECO mode.
5. Remove the cap from the filler neck of the expansion tank. Caution: If the engine is not yet completely cool, wrap the cover with a cloth to eliminate the risk of scalding.
6. Raise and place the car on stands, remove the engine crankcase protection, (see Chapter 2, Section 5).
7. Substitute a clean container of the appropriate volume under the radiator. For the convenience of draining the coolant, it is recommended to put on the drain pipe (see resist. illustration) lower the hose and its other end into the prepared container.
8. Open the drain valve on the radiator and drain the liquid.
9. Close the valve and lower the car.
Refueling
10. Check up serviceability of a condition and reliability of fastening of all hoses of a cooling path. Replace defective components, tighten clamps (see Section 4).
11. Remove the cap of the expansion tank and start slowly pouring a fresh mixture of antifreeze with water into the neck of the latter. Continue filling until the liquid level in the tank rises to the level of the lower nozzle (see resist. illustration) expansion tank.
12. Reinstall the expansion tank cap.
13. Start the engine and allow it to warm up to normal operating temperature, while increasing the engine speed to 2500 rpm so that the first stage of the fan turns on.
14. Remove air from the cooling system, to do this, let the engine run for 2 minutes at a speed of 2000-2500 rpm. In this case, the air in the cooling system is removed through the return and connecting hoses of the expansion tank (see illustration 1.2).
15. Inspect the cooling system components for signs of leaks, then stop the engine and allow it to cool completely.
16. If equipped, install the crankcase protection.
17. Finally, check the coolant level again and correct if necessary (see chapter 1). Tighten the expansion tank cap.
