Pipe/hose between compressor and condenser (pressure side), replacing

Removing the pipe/hose between the compressor and the condenser





Remove:
- the rear/upper pipe/hose connector (1) on the compressor.
- the front bumper cover. See: Cover bumper front Service and Repair




Lower the vehicle.
Disconnect the rear connector (1) to the condenser, to the left of the right-hand headlamp. See the illustration.
Route the pipe/hose down to the compressor under the vehicle.

Installing the pipe/hose between the compressor and the condenser

Note! For tightening torques, see Specifications. [1][2]Body and Frame

Place the pipe/hose for the compressor in position by the upper connector to the condenser.

Install:
- the pipe coupling, 1 M8. Ensure that the O-rings are securely located between the condenser and the pipe/hose. Tighten the screw
- the pipe coupling by the compressor, 1 M8. Make sure the O-rings are securely located. Tighten the screw
Carry out finishing work. See: Finishing.
