AC Hose Chaffing Repair

AFFECTED VEHICLE RANGE:
New Range Rover (LM) 3A101029 to 4A173623

SITUATION:
AC INOPERATIVE

A customer may report a concern that the air conditioning (A/C) has ceased to operate. The A/C hoses at the front of the engine bay may be in contact. The resulting chaffing of the hose can lead to loss of refrigerant.

RESOLUTION:
REPLACE DAMAGED HOSES

Should a customer complain of inoperative Air Conditioning, determine the cause or the source of the leak. Install a hose retaining clip between the compressor and the intermediate pipes and replace any affected A/C hoses.

REPAIR PROCEDURE

INSPECT AND REPLACE DAMAGED HOSES





NOTE:
A contact condition between the two pipes in the area illustrated in Figure 1 is the likely cause of refrigerant loss.

1. Visually inspect the A/C hose from the compressor to the intermediate pipe for damage.

2. If hose damage is NOT the cause of the refrigerant loss, further diagnosis will be required to determine the A/C system fault.

NOTE:
GTR lookup sequence is as follows:

GTR Home>NAS>Service Information/LM Range Rover/2004>Workshop Manuals> Range Rover Workshop Manual Service Procedures> Bookmark "82 Air Conditioning">Link "82.30.02 Refrigerant recovery - recycling and recharge".

3. If it is determined that hose damage is the cause of the refrigerant loss and subsequent A/C system failure, perform the following:

^ Refer to GTR Workshop Manual Section 82.30.02 and recover any refrigerant remaining in the A/C system.

^ Replace the damaged hose(s).

^ Install the clip between the two A/C hoses.

4. Refer to GTR Workshop Manual Section 82.30.02 and recharge the A/C system.

5. Check the A/C system operation.
