Draining the coolant
Place the vehicle on a two-post lift, apply the parking brake, turn off the ignition and disconnect the battery ground terminal (electro-hydraulic lift type P-3.2G with lifting capacity of 3.2 t, spanner 10).
Unscrew plug 1, Figure 10-2, of the expansion tank.
Figure 10-2 - Expansion tank of the engine cooling system: 1 - expansion tank cap; 2 - expansion tank of the engine cooling system; 3 - engine cooling system nipple
Remove the engine crankcase protection in accordance with the requirements of TI 3100.25100.20594.
Install a process container to collect the coolant (technological capacity).
Remove clamp 1, Figure 10-3, of outlet hose 2 of radiator 3 of cooling system (device for removing elastic clamps Mot. 1202 or Mot. 1448).

Disconnect the radiator drain hose.
Blow a stream of compressed air through the opening of the expansion tank to remove the coolant using an air gun.
Flushing the cooling system
Fill the cooling system with water through the expansion tank.
Flush water through the cooling system until the water coming out of the radiator outlet hose of the cooling system is clear.
Filling the cooling system
Install the outlet hose 2, Figure 10-3, onto the radiator pipe 3 of the engine cooling system.
Install clamp 1 of the radiator outlet hose of the cooling system (device for removing elastic clamps Mot. 1202 or Mot. 1448).
Unscrew the plug of the fitting 3, Figure 10-2, of the engine cooling system to remove air.
Fill the engine cooling system with coolant, pouring it into the expansion tank (coolant in accordance with the current "Codifier of main and auxiliary materials used in maintenance and repair of LADA vehicles" K 3100.25100.00018).
Close the bleed screw plug as soon as the coolant starts to flow out in a continuous stream.
Install cap 1 of the expansion tank.
Connect the ground wire terminal to the battery (spanner 10).
Start the engine.
Run the engine at 2500 rpm until the electric cooling fan comes on for the third time.
Check the heater's functionality.
After stopping the engine, check for signs of coolant leakage.
Bring the coolant level up to the "Maxi" mark on the expansion tank.
Install the expansion tank cap.
Install engine crankcase protection in accordance with the requirements of TI 3100.25100.20594.
Present the vehicle to the Quality Control Department. The Quality Control Department will check the vehicle for compliance with the requirements of TU 017200-254-00232934, paragraphs 1.19.6, 1.19.9, 1.19.10, 1.19.14.
