Before starting work on the condenser

Warning! Follow the safety instructions for work on air conditioning systems. See applicable service precautions.

Note! First read the instructions covering slow and fast leaks. See Oil in the A/C system Service and Repair.

Note! Always plug the pipes and connections when working on the climate control system.

Condenser - Work in the engine compartment
- Disconnect the battery negative lead. See Battery, replacing Battery, Replacing
- Drain the refrigerant from the system.



- Remove the air pipe from the control module box.




- Remove the upper screws holding the air conditioning aggregate together. Pull the aggregate outwards slightly.




- Remove the screws from the upper mountings on the air conditioning aggregate.

Condenser - Work under the car





Remove:
- the air baffle.





Remove
- the pipe coupling from the receiver / dryer.





The lower mounting for the air conditioning aggregate:
- Partially slacken off the screws on the right-hand side
- Remove the screws on the left-hand side.




Slightly lower the air conditioning aggregate on the left-hand side. This is to access the screw.

Remove
- the screw from the hose / pipe coupling between the compressor and the condenser.
Use a curved ring spanner
- the hose from the catch on the condenser. Carefully push the hose to one side.




- Slacken off the lower screws holding the air conditioning aggregate together. Pull the aggregate outwards slightly
- Press the air conditioning aggregate backwards. Lower the condenser slightly. Remove the pressure sensor on the receiver
- Remove the condenser
- Remove the receiver / dryer. See Accumulator / receiver drier, replacing Service and Repair.

Installation

Condenser - Work under the car
- Screw the protective sleeve loosely into place on the service valve
- Install the receiver / dryer. See Accumulator / receiver drier, replacing Service and Repair.
- Fill the condenser with oil.
Note! Always use new O-rings lubricated with compressor oil.

- Press the air conditioning aggregate backwards. Push the condenser up slightly. Install the switch from the pressure sensor on the receiver.




- Thread in the lower screws for the air conditioning aggregate
- Check that the condenser is in the correct position against the air conditioning aggregate. Tighten the screws for the air conditioning aggregate.




- Position the hose / pipe from the compressor in the mounting hook. Position the hose / pipe in the hose connector on the condenser
- Thread and tighten the screw by hand so that the hose connector touches the bottom
- Tighten the screw for the hose connector from the compressor. Tighten to 25 Nm ±6 Nm.




- Position the air conditioning aggregate against the rubber seals. Tighten the screws for the air conditioning aggregate against the member
- Check that the seals are correctly positioned.




- Install the hose connector for the receiver. Tighten. Tighten to 10 Nm.




- Install the air baffle.




- Thread the upper screws for the air conditioning aggregate on the condenser. Tighten the screws.




- Thread the screws on the upper mountings on the air conditioning aggregate. Tighten the screws.
- Vacuum pump the system and test for leaks.
- Fill the system with refrigerant and check for leaks.
- Connect the battery negative lead. See Battery, replacing Battery, Replacing.
