2. Undo the bolt (2a) and disconnect the coolant fluid inlet and outlet pipes (2b) from the compressor.

Seal the disconnected connectors, using suitable plugs, to prevent humidity and impurities from entering the system.

1. Remove the bolts (1a) and remove the air conditioning compressor (1b). Refitting ( Removing ) If replacing the compressor, proceed as follows.1. Remove the drain plug and drain the fluid from the compressor.

Manually rotate the compressor to facilitate the removal of all the fluid.

the fluid is extremely hygroscopic: avoid leaving the containers open. Avoid leaving the compressor or any other component disconnected from the system for longer than is strictly necessary.

1. Recover the fluid drained from the compressor in a suitable transparent container (quantity A).2. Drain and recover the fluid from the new compressor (quantity B) in an identical container, following the instructions given previously.3. Introduce the same amount of fluid removed from the compressor being replaced into the new compressor (eliminate quantity C = B - A). Fit the air conditioning compressor and support it using the bolts.1. Connect the coolant fluid inlet and outlet pipes (1a) to the compressor and fix them tightening the bolt (1a) to the recommended torque.

Replace the O-Ring seals for the connectors. Only use green coloured seals, resistant to R134A coolant fluid. Lubricate the thread of the connectors using anti-freeze.
