Removing ( Refitting )
Follow the safety instructions.    Op. 5040 AIR CONDITIONING CASING AND COMPONENTS
- Position the vehicle on a lift.    Op. 0010T84 COOLANT FOR AIR CONDITIONING SYSTEM - DEHYDRATE AND REPRESSURIZE 1. Undo the bolt (1a) and disconnect the connector (1b) from the compressor (1c).
Seal the connectors that have been disconnected using suitable plugs to prevent dampness and impurities from entering the system.

2. Unscrew bolts (2a) securing compressor (2b to slacken belt (2c) from compressor to alternator.3. Recover compressor (2b) and belt (2c).
Belt (2c) must be replaced.
- If the compressor is being replaced, proceed as follows.1. Drain the fluid from the compressor through the drainage opening (1a) after having removed the screw plug (1b) and throught the attachment openings for the pipe connectors (1c). If necessary, rotate the compressor several times manually, using the pulley to ensure that all of the fluid comes out.
The fluid is extremely hygroscopic: avoid leaving the containers open. Avoid leaving the compressor or any of the components disconnected from the system for any longer than is strictly necessary.
1. Collect the fluid drained from the compressor in a suitable transparent container (quantity A).2. Drain the fluid from the new compressor (quantity B) and collect it following the instructions given previously.3. Reintroduce a quantity of oil into the new compressor that corresponds to what was removed from the compressor being replaced (C=B-A).4. The fluid should be introduced into the compressor through the pressurizing/drainage opening- Tighten the screw cap to the recommended torque.

Refitting ( Removing ) - Check that the compressor is not damaged.1. Reposition the compressor.2. Screw in the upper compressor bolt (2a) without tightening it.3. Fit a new belt (3a) from the compressor to the alternator.4. Apply a column jack (4a) beneath the left side of compressor (1), then raise until it can be inserted in its housing and tighten lower compressor bolts (4b).Belt (3a) is also tensioned at this stage.5. Tighten bolts (2a) and (4b) to the specified torque.

Replace the O rings for the connectors. Only use green coloured seals that are resistant to R134a coolant. Lubricate the connector threads using anti-freeze.
1. Connect the connector (1a) for the pipe to the condenser and secure it tightening the bolt (1b) to the recommended torque.
