What This Product Does

The condenser receives hot, high-pressure refrigerant from the compressor and releases its heat through the cooling fins. This changes the refrigerant from a gas into a liquid before it continues through the air conditioning system.

Functions

• Releases heat carried by the refrigerant
• Condenses high-pressure refrigerant gas into liquid
• Supports consistent cabin cooling
• Maintains the required refrigerant flow through the A/C circuit

Technical Details

• Product type: air conditioning condenser
• Porsche part number: 99757391105
• Brand: genuine Porsche
• Diagram quantity: two condensers per listed assembly

The condenser appears in Porsche refrigerant-circuit and front water-cooling diagrams for the 996, 997, 987 Boxster and 987C Cayman. The 996 diagram data includes the production note 02- and C4S application.

Symptoms of Fault

• Gradual reduction in air conditioning performance
• Warm or inconsistently cooled air from the vents
• Visible corrosion, bent fins or impact damage
• Oily residue or leak-detection dye around the condenser
• Refrigerant loss after the system has been recharged
• Restricted airflow caused by debris between the cooling fins

Why Replacement Matters

Condensers are positioned at the front of the vehicle, where moisture, road salt, debris and stone impacts can cause corrosion or leaks. Replacing a damaged or leaking unit helps restore correct refrigerant circulation and heat transfer. The system should be leak-tested and evacuated before being refilled, and the condition of the desiccator, seals and connected refrigerant lines should also be checked.

FAQs

• Can a condenser be cleaned? External debris may be removed carefully, but a leaking, heavily corroded or physically damaged condenser requires replacement.
• Should the desiccator also be renewed? Replacement is normally recommended when the refrigerant circuit has been open or contaminated.
• Is a vacuum test required? The repaired circuit should be evacuated and checked for leak tightness before the correct refrigerant charge is added.

Check fitment for your specific vehicle, including model, year and engine, before ordering.
