Evaporator

To remove


Important

If the pipes between the evaporator and the grommet in the bulkhead are jointless, they must be cut. Therefore, a new evaporator must then be fitted.



1. Drain the refrigerant from the A/C system; see Draining and filling the refrigerant .

2. Remove the glove box .

3. Cut the cable tie holding the wire harness to the service cover. Also cut the cable tie holding the cooler hose to the glove box.

4. Remove the service cover.


5. Remove the fresh-air filter and filter element or particle filter.

6. Remove the ventilation fan, see Ventilation fan .


7. Cut the A/C pipes to the evaporator with a sheet metal cutter or air-driven jigsaw.

The pipes are accessible from the engine compartment by the air recirculation flap.

8. Pull out the evaporator.


9. Detach the temperature sensor from the evaporator.

10. Remove the expansion valve, see Expansion valve .

11. Pull out the pipes from inside the cabin.

12. Vacuum pump the climate housing to remove any cuttings.


To fit



1. Make a hole for the temperature sensor in the centre of the 5th cooling fin on the evaporator (from the passenger side). Use a tool with a rounded point, e.g. a cross-head screwdriver with diameter 4.5 mm.

Fit the temperature sensor in the evaporator.

2. Adjust the oil level in the compressor; see Filling and adjusting compressor oil level .

3. Insert the plugged pipe set from inside the cabin.

4. Position the filter retainer against the evaporator.

5. Push in the evaporator to the climate housing.

6. Remove the plugs in the A/C pipes and fit the expansion valve, see Expansion valve .

7. Position the PAD connection with the corresponding pipe set.


8. Locate the bolt in the PAD connection and tighten it from inside the engine compartment by the air recirculation flap.
