1. Disconnect the cable from the negative pole of the battery.
2. Carefully drain coolant.
3. Disconnect the line and hose from the evaporator joints on the heat shield in the engine compartment. Hold the joints with a second wrench. Cover joints immediately to prevent dirt from entering
4. Remove the sealing rings from the thermal barrier. Disconnect the drain hose from the evaporator housing.
5. Remove the glove box and frame.
6. In the evaporator, loosen the sealing strip; slide it towards the fan.

13. Remove the expansion valve if necessary.
For installation:
14. Assemble casing components as needed. Install the capillary tube in its original location. Assemble the top and bottom halves of the casing, making sure that there are no gaps in the casing.
15. Install the evaporator assembly and fasten the fixing bolts. Remember to connect the evaporator drain hose and route it outside the vehicle.
16. Connect the thermostat wire and secure it with a clip.
17. Install the sealing strip and tighten it. Check correct location.
18. Install the glove box and frame.
