AFFECTED VEHICLE RANGE:
New Range Rover (LM) Up to 4A154045
18
SITUATION:
CUSTOMER COMPLAINT OF POOR COOLING
The flux used when brazing the condenser crystallizes forming a white substance. The substance contaminates the inside of the condenser tube,
causing the plug not to seal correctly.
RESOLUTION:
INSPECT FOR LEAK AND REPLACE CONDENSER IF INDICATED
If the customer complains of poor cooling, determine if refrigerant is leaking from the condenser drier desiccant bag plug. If desiccant bag plug is
leaking, replace the condenser without attempting to repair the leak.
PARTS INFORMATION
DDW WARRANTY CLAIMS:
DDW requires the use of causal part numbers. Labor only claims must show the causal part number with a quantity of zero.
REPAIR PROCEDURE
DETERMINE LEAK SOURCE AND REPLACE CONDENSER IF INDICATED
NOTE:
If refrigerant is leaking from the condenser drier desiccant bag plug, DO NOT remove the plug:
^ Attempting to remove the flux (white substance) from the condenser bore may result in damage to the condenser bore and
contamination inside the condenser.
^ Leaving the plug undisturbed will allow the supplier of the condenser to verify that flux contamination was the cause of the leak, and
also to verify that there are no other causes for the leak.
1. Verify source of leak is from the condenser drier desiccant bag plug.
2. If refrigerant is leaking from the condenser drier desiccant bag plug, refer to RAVE/GTR section 82.15.07 and replace the condenser.
