Symptoms of Fault

Declining cooling effectiveness or traces of oil or leak-detection dye around a connection can indicate refrigerant leakage. Similar symptoms can originate elsewhere, so identify the leaking joint before choosing replacement parts.

Why Replacement Matters

Renewing a defective connection seal addresses a potential escape path for refrigerant. Check the adjoining pipework and sealing surfaces as part of the repair; changing an O-ring will not correct damage elsewhere in the circuit.

FAQs

Does weak cooling always mean this seal has failed?
No. Condenser damage, other leaking connections and unrelated air-conditioning faults can produce similar symptoms.

Is this supplied as a set?
No. Each O-ring is supplied individually; confirm the number needed for the connections being repaired.

Who should carry out the work?
Use an appropriately qualified air-conditioning technician for work involving refrigerant.

What This Product Does

The condenser transfers heat from pressurised refrigerant into the passing air, allowing the refrigerant to condense into liquid. It belongs to the air conditioning circuit rather than the engine coolant circuit.

Functions

• Releases heat carried by the refrigerant.
• Enables refrigerant condensation within the A/C cycle.
• Supports cabin cooling as part of the complete system.
  
  

Technical Details

• Condenser reference in the supplied diagrams: 99157311106.
• Installation position: front, left or right.
• The referenced assemblies show two condensers per vehicle; this listing is for one.
  
  

Symptoms of Fault

• Vent air remains warm or cooling gradually diminishes.
• Oily deposits appear around the condenser or its connections.
• Visible fin deterioration, impact damage or corrosion.
• Debris obstructs airflow through the condenser.

These signs warrant inspection but do not, by themselves, establish that the condenser needs replacing.

Why Replacement Matters

A leaking or damaged condenser can prevent the refrigerant circuit from operating correctly. Replacement addresses the defective component rather than relying on repeated refrigerant top-ups. Inspect adjoining pipe connections, seals and air guides during the repair. OE Match focuses on Porsche replacement applications, using original references and fitment checks when specifying components.

FAQs

Will another regas resolve weak cooling?
Not if refrigerant is escaping. Locate and repair any leak before recharging.

Should the receiver-drier also be checked?
Yes. Have the technician assess its replacement requirements when opening the refrigerant circuit; it is a separate component from this condenser.

Can cleaning avoid replacement?
Removing external debris may improve airflow, but cleaning cannot repair perforations or leaking joints.

Who should install it?
Use an appropriately qualified air conditioning technician for refrigerant recovery, installation, leak testing and recharging.

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.

Air conditioning systems operate under pressure and depend on correctly sized, serviceable seals at their connections. Even a small or inexpensive O-ring can be critical to maintaining system integrity and reliable A/C performance.  

What This Product Does:

The A/C O-ring seals the joint between compatible air conditioning pipes, hoses and components.

When the connection is assembled, the O-ring is compressed between the mating surfaces to create a pressure-tight seal. This helps keep refrigerant and circulating compressor lubricant contained within the closed air conditioning circuit.

A correctly functioning O-ring helps:

• Prevent refrigerant leakage
• Maintain A/C system pressure
• Prevent loss of refrigerant oil at the connection
• Keep moisture and contamination out of the system
• Support efficient air conditioning operation
• Maintain a secure seal between connected A/C components

Correct dimensions and material compatibility are especially important in an air conditioning system because the seals are exposed to refrigerant, lubricant, pressure and temperature changes.

Symptoms Of Wear Or Failure:
Over time, an O-ring can deteriorate through age, heat, chemical exposure and repeated temperature and pressure cycles.

Common signs of a leaking or failed air conditioning O-ring include:

• Air conditioning gradually losing cooling performance
• A/C blowing warmer than expected
• Refrigerant charge repeatedly becoming low
• Refrigerant leakage detected around a connection
• Oily residue around an A/C pipe or fitting
• System unable to maintain pressure
• O-ring becoming hard or brittle
• Cracks or splits in the sealing material
• Flattened or permanently compressed O-ring
• Cuts, nicks or deformation after removal

A refrigerant leak can be extremely small and may not always be visually obvious. Proper A/C leak-detection and diagnostic equipment may therefore be required to identify the source accurately.

Why Replacement Matters:
The air conditioning system relies on being sealed and correctly charged to operate effectively. A deteriorated O-ring can allow refrigerant to escape gradually, resulting in reduced cooling performance and eventually preventing the A/C system from operating correctly.

Loss of refrigerant can also be accompanied by loss of compressor lubricant from the affected connection. Maintaining the correct refrigerant and lubricant charge is important for dependable system operation.

Replacing a leaking or damaged O-ring helps restore:

• A secure A/C connectionRefrigerant retention
  
• Correct system pressure
• Reliable cooling performance
• Protection against moisture and contamination entering the system

Addressing a small seal leak promptly can also prevent repeated refrigerant loss and unnecessary recharging of the system.

CFS Aluminium Radiator air conditioning (Air Con) condenser.
CSF has decades of experience designing and manufacturing A/C Condensers, and has once again applied modern design and manufacturing techniques to these classic Porsche platforms. The result is a condenser that fits perfectly, outperforms the factory system by a significant margin, and costs less than a new OEM unit

Fits:
Porsche 996 911 (Carrera, 4, 4S, Targa, & GT3) 1999-2005
Porsche 986 Boxster (Base, S, Roadster, & Roadster S) 1997-2005

OEM Part Numbers: 9975739101, 99657311100

The CSF 996/986 Condenser utilizes a modern parallel-flow core design similar to the original OE unit. However, the CSF 18mm 8-channel microtube core offers better flow and more surface area contact for superior heat transfer. The 8mm tall multi-louvered fins further improve heat transfer over the basic fin design of the OE unit. Together, these features offer better heat dissipation for the refrigerant while increasing airflow to the radiators behind them.

Key Differences and Improvements:
• Increased performance: Approximately 5% better performance than a brand-new OEM condenser and much larger improvement over a clogged or dirty unit that has been installed for some time.
• More airflow to the radiator behind the condenser for better engine cooling performance
•  Improved Durability: More robust design and construction materials
•  Less Expensive: Around half the price of a new Genuine Porsche unit

Why Upgrade?
Whether you are restoring a 996 or 986 to show-car condition or upgrading your weekend toy for more comfort, CSF’s OEM+/Performance A/C Condenser is a no-brainer. It is a straight forward plug-and-play installation, more efficient, and built to last.
