Undo the bolt fixing the pipe connector from the drier filter.2. Disconnect the connector from the drier filter.

Lower the vehicle.1. Undo the nut for the intermediate coupling for the pipe from the evaporator to the compressor.2. Disconnect the coupling.

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

1. Undo the bolt fixing the pipes to the evaporator.

1. Disconnect the pipes from the retaining bands on the bodyshell.2. Undo the bolts fixing the engine coolant reservoir.3. Move the reservoir.4. Remove the pipes.

1. Work at the bench and remove the pipe bands.2. Separate the pipe from the evaporator to the drier filter (2a) from the evaporator inlet pipe (2b) and recover the bush (2c).

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

Refitting ( Removing

) Check that the pipe is not damaged and that there are no cracks which would affect the seal.Join the pipe from the evaporator to the drier filter with the evaporator inlet pipe using the bush and the bands.

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 pipes and connect them to the bodyshell using the retaining bands.Connect the connectors for the pipes to the evaporator and secure them using the bolt.
