Compressor

K4J or K4M or K9K

REMOVAL

• Position the vehicle on a two-post lift.
• Disconnect the battery, starting with the negative terminal.
• Drain the refrigerant circuit using the charging station tool.
• Remove:

• the engine undershield,
• the front right wheel,
• the mudguard,
• the front bumper (see Front Bumper).

• Remove:

• the reinforcing plate (1),
• the drive belt (see Drive Belt).

WARNING: Always replace a belt that has been removed.

• Unscrew the pipe connections (2) from the compressor.
• Disconnect the pipes.
• Fit plugs to the openings.

• Disconnect the compressor connector (3).
• Remove:

• the three compressor mounting bolts (4),
• the compressor.

INSTALLATION

• Refit in the reverse order of removal.

• When replacing a compressor, do not add oil.
• Strictly observe the instructions regarding oil top-up when working on air conditioning circuit components (Chapter Air Conditioning).

• Replace the seals.
• Lubricate with the recommended air conditioning oil to ease fitting.

WARNING: Any damaged seal requires replacing the pipe.

• Tighten to the following torques:

• the compressor mounting bolts (2.5 daN.m),
• the reinforcement plate mounting bolts (2.1 daN.m),
• the pipe connection mounting bolts (1 daN.m),
• the battery cover bolts (0.4 daN.m).

• Refill the refrigerant circuit using the charging station tool.

Connect the battery; carry out the necessary relearn procedures (Chapter Battery).

• Check the air conditioning operates correctly with the fan unit at maximum speed.
• If there is no cooling, carry out a leak check (see Air Conditioning chapter).
