2. Undo the bolt fixing the pipe connector.3. Disconnect the pipe and move it.

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

4. Undo the nut.5. Release the bracket and move the pipe away.

Raise the car.1. Fit a spanner (1a) on the tensioner nut (1b) and rotate it until the belt (1c) can be released from the compressor pulley (1d). 2. Undo the lower bolts fixing the compressor.3. Remove the compressor.

If replacing the compressor, proceed as follows.1. Remove the plug for the compressor being replaced.Drain the fluid contained in the compressor. If necessary, rotate the compressor several times, manually, to remove 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.

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.

3. Introduce the same amount of fluid removed from the compressor being replaced into the new compressor (eliminate quantity C = B - A).

Refitting ( Removing

) Check that the compressor is not damaged.Reposition the compressor.Tighten the lower bolts fixing the compressor.Fit a spanner on the tensioner nut and rotate it until it is possible to fit the belt on the compressor pulley.Lower the vehicle.Tighten the upper bolts fixing the compressor.Position the pipe and secure it with the nut to the relevant bracket.Follow these precautions.

Replace the O-rings for the connectors.

Only use green coloured seals, resistant to R134A coolant fluid.

Lubricate the thread of the connectors using anti-freeze.

Position the pipe connector and tighten the fixing bolt.
