To complete the work, you will need two new rubber gaskets for the heater valve, a worm clamp with a diameter of 16-23 mm and coolant.
Work is carried out with a cold engine.
Removing
1. We prepare the car for operations (see "Vehicle preparation for maintenance and repair").
2. In the engine compartment, use a screwdriver to loosen the inlet hose clamp and remove the hose from the tap (lower branch pipe) (see "Heater radiator - replacement").
3. Set the lower lever of the ventilation system control unit to the extreme right position, closing the air dampers of the side air ducts.
4. Remove the storage shelf and storage box body (see "Dashboard - removal and installation").
5. Using a 10 mm socket wrench, unscrew the nut securing the right air duct to the body and remove the air duct from the stud and disconnect it from the instrument panel side deflector.
6. Disconnect the right air duct from the radiator shroud (see "Heater fan motor - replacement").
7. Using a 7 mm socket wrench, loosen the bolt securing the heater tap drive rod.
8. Having released the thrust shell from under the bracket, remove the thrust tip from the crane lever.
9. Using a 10 mm spanner, unscrew the two bolts securing the faucet to the radiator. In order for the lower embedded nut not to fall out of the socket, we fix it with plasticine.
10. Remove the tap, removing its branch pipe from the seal located in the partition of the engine compartment (see "Heater radiator - replacement"). The junction of the faucet and radiator flanges is sealed with a rubber gasket. At the same time, a small amount of coolant may leak out of the heating radiator; a rag should be placed to collect it.
11. Using a 10 mm wrench, unscrew the two bolts securing the pipe to the faucet.
12. Remove the pipe. The junction of the flanges of the valve and the branch pipe is sealed with a rubber gasket.
Installation
1. Replace rubber gaskets with new ones.
2. Install the heater valve in reverse order.
3. Move the heater tap control lever to the far right position.
4. Add coolant (see "Coolant - level check and replacement").
5. After filling the system with coolant, we check the tightness of the connections of the valve with the radiator and hose. Tighten them if necessary.
6. Installation of other parts is carried out in reverse order.
