Connecting hoses

Disconnect the battery.

Drain the R134a refrigerant circuit using the recharging station.

LOW PRESSURE HOSE

REMOVAL

Remove the mounting bolt from the expansion valve.

Fit plugs to the expansion valve and the hose.

Remove the mounting bolt from the compressor.

Fit plugs to the compressor and the hose.

Unscrew the hose retaining bracket.

Remove the low pressure hose.

INSTALLATION

Reverse the removal procedure.

Check the condition of the seals and lubricate them with P.A.G. SP 10 oil.

When replacing a hose, add 10 ml of SP 10 oil. If a hose has burst (rapid leak), add 100 ml.

Evacuate the system, then charge the R134a refrigerant circuit using the recharging station.

NOTE:

• Hose retaining bolt on compressor: 2.1 daN.m

• Hose retaining nut on expansion valve: 0.8 daN.m

• Hose retaining bolt on condenser: 0.8 daN.m

Disconnect the battery.

Drain the R134a refrigerant circuit using the recharging station.

HIGH PRESSURE HOSE, COMPRESSOR-CONDENSER

REMOVAL

Remove the mounting bolt from the compressor.

Fit plugs to the compressor and the hose.

Remove the mounting bolt from the condenser.

Remove the hose.

Fit plugs to the condenser and the hose.

NOTE: on engine E7J versions, the front bumper must be removed to access the bolt securing the "damper" (1).

INSTALLATION

Reverse the removal procedure.

NOTE: When refitting this connecting hose to the compressor, it is essential to fit all the bolts, then bring them into contact before tightening to torque. The aim is to ensure correct hose positioning so as not to damage it at the "damper" (1). Check the condition of the seals and lubricate them with P.A.G. SP 10 oil.

When replacing a hose, add 10 ml of SP 10 oil. If a hose has burst (rapid leak), add 100 ml.

Evacuate the system, then charge the R134a refrigerant circuit using the recharging station.

Disconnect the battery.

Drain the R134a refrigerant circuit using the recharging station.

HIGH PRESSURE HOSE, RECEIVER-DRIER - EXPANSION VALVE

REFITTING Release the hose from its clips.

Disconnect the pressure sensor connector.

Remove the mounting bolt from the expansion valve.

Fit plugs to the expansion valve and the hose.

Remove the mounting bolt from the receiver-drier.

Fit plugs to the receiver-drier and the hose.

Remove the hose.
