2891806 - 5040A20 air conditioner compressor - r+r - includes fluid level check and top up if necessary

Follow the safety instructions (  See assembly 5040A   air conditioner coolant circuit ).

Removing ( Refitting ) Drain the coolant fluid (see op.   5040A10  Air conditioning refrigerant CIRCUIT - Draining and Refilling ). Remove the right front wheel and wheel arch.Loosen the air conditioning compressor drive belt.1. Remove the drive belt from the compressor pulley.2. Undo the bolt fixing the pipe connector.3. Disconnect the pipe connector.

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

4. Undo the bolts fixing the compressor.5. Disconnect the electrical connection for the compressor.

6. Remove the compressor. If replacing the compressor, proceed as follows.1. Remove the plug for the compressor being replaced.Drain the fluid from 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 bolts fixing the compressor.Connect the compressor pipe connector and tighten the fixing bolt.

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.
