Evaporator high and low pressure pipes, Z19DT/DTH

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

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

3. Remove the cover on the bulkhead partition space .

4. RHD: Remove the Windscreen wiper assembly .

5. LHD: Remove the fresh-air filter and fresh-air filter housing.

6. Remove the high and low pressure pipes' PAD connection from the expansion valve. Plug the openings.


7. Remove the hose between the turbo inlet pipe and air filter housing.

8. Unplug the mass air flow sensor connector.

9. Remove the cover from the air filter housing

10. Remove the filter.


11. Dismantle the pressure sensor connector. Exercise care so that the pressure sensor is not damaged.


12. Dismantle the lower part of the air filter housing. Press out the induction manifold so that it becomes loose before the air filter housing is lifted out.
