Radiator air conditioning (Air Con). Porsche Cayenne 957  ›  95557311105

The OE Match Radiator Air Conditioning Condenser is a replacement air-conditioning condenser for selected Porsche Cayenne 957 petrol models from 2007–2010.

• Porsche 957 Cayenne 2007 - 2010 (not for Diesel models)

Mounted at the front of the vehicle where it receives cooling airflow, the condenser performs a similar heat-exchange function to a radiator but forms part of the air-conditioning refrigerant circuit rather than the engine cooling system.

Hot, high-pressure refrigerant leaving the A/C compressor enters the condenser, where heat is transferred to the surrounding air. As the refrigerant cools, it condenses from a high-pressure gas into a high-pressure liquid before continuing through the remainder of the climate-control system.

A correctly functioning condenser is essential for efficient cabin cooling, stable system pressures and reliable air-conditioning operation.

What This Product Does:
The A/C condenser removes heat from the refrigerant after it has been compressed.

Its main functions include:

• Dissipating heat from the air-conditioning refrigerant
• Converting high-pressure refrigerant gas into liquid
• Supporting effective cabin cooling
• Helping maintain correct refrigerant pressures
• Working with the compressor, receiver/drier and evaporator
• Providing sufficient heat exchange during hot-weather operation
• Maintaining efficient operation of the complete A/C system

Without adequate condenser performance, the refrigerant cannot reject heat efficiently and cabin cooling will deteriorate.

Symptoms Of Wear Or Failure:
Common signs of condenser deterioration include:

• Weak air-conditioning performance
• Warm air from the cabin vents
• Cooling becoming less effective over time
• Complete loss of A/C cooling
• Refrigerant leakage
• Oily residue on or around the condenser
• Hissing caused by refrigerant escaping
• Bent cooling fins
• Corroded condenser fins
• Visible impact damage
• Refrigerant pressure faults
• Compressor cycling excessively
• Poor cooling in hot weather
• A/C performance improving only while the vehicle is moving

These symptoms can also be caused by other A/C components, so the system should be correctly diagnosed before replacement.

Why Replacement Matters:
A damaged condenser reduces the ability of the A/C system to reject heat.

Continued operation with a defective condenser may result in:

• Refrigerant loss
• Poor cabin cooling
• Incorrect system pressures
• Increased compressor workload
• Compressor overheating
• Reduced A/C efficiency
• Additional damage to the refrigeration system

Replacing a leaking, blocked or badly damaged condenser restores the heat-exchange capacity required for normal air-conditioning operation.
