Evaporator's high and low-pressure pipes, Z19DTR

Important

The A/C receiver and the compressor oil absorb moisture from the air, which can then not be removed. Plug all connections that are opened immediately.


To remove


1. Put the car on a lift.

2. Drain the refrigerant from the A/C system, see Draining and filling the refrigerant .

3. Remove the windscreen wipers. Use the puller 85 80 144 Puller, windscreen wiper arm .

4. Remove the cover on the bulkhead partition space .

5. RHD: Remove the Windscreen wiper assembly .

6. LHD: Remove the fresh-air filter (A) and the fresh-air filter housing (B).


7. Unplug the mass air flow sensor connector (C).


8. Remove the hose between the turbo intake manifold and the air cleaner housing.

9. Remove the cover from the air filter housing (E).

10. Remove the filter (F).


11. Remove the lower part of the air filter housing (G). Press out the intake manifold (H) so that it becomes loose before the air filter housing is lifted out.


Important

Take care when releasing the locking mechanism on the connector so as not to damage the connector. Pull the halves straight apart to avoid bending the pins. For further information regarding connectors, refer to Connectors, handling and inspection .


12. Unplug the pressure sensor connector (I). Take care that the pressure sensor is not damaged.


13. Detach the high and low pressure pipes' PAD connection (J) from the expansion valve. Plug the openings.


14. Detach the high and low pressure pipes' PAD connection (K) by the right-hand front structural member. Plug the openings.


15. Detach the evaporator's high and low pressure pipes from the clips (L) and the seal (M). Lift out the pipe.


To fit


1. Adjust the oil quantity in the A/C system. See Filling and adjusting the compressor oil .

2. Move the high and low pressure pipes into position, and secure the pipes in the clip (L) and the seal (M).

3. Replace the sealing washers and attach the high and low pressure pipes' PAD connection (J) to the expansion valve.
