Information
Air conditioning expansion valve
The expansion valve is located within the air conditioning evaporator housing and acts as a precision regulator for refrigerant flow. It reduces the pressure of the refrigerant before it enters the evaporator and controls the amount of refrigerant that passes through the system.
Fits:
Porsche 986 Boxster 1997 - 2004
Porsche 987 Boxster 2005 - 2008
Porsche 987C.1 Cayman 2005 - 2008
Porsche 987C.2 Cayman 2009 - 2013
Porsche 996 1998 - 2005
Porsche 997.1 2005 - 2008
Diagram ref no 4
This OE Match version matches the original Porsche specifications for size, mounting configuration and flow characteristics. This ensures correct refrigerant pressure regulation and compatibility with the A/C systems used in Porsche 986, 987, 996 and early 997 vehicles.
A properly functioning expansion valve is essential for maintaining consistent cooling performance and preventing irregular cabin temperatures.
The expansion valve controls refrigerant flow into the evaporator by adjusting pressure and volume according to system demand. This allows the refrigerant to expand and cool effectively, enabling the evaporator to remove heat from the cabin air.
If the valve fails or becomes restricted, the air conditioning system may lose cooling efficiency or produce inconsistent temperatures.
Function
• Refrigerant Flow Control: Regulates refrigerant entering the evaporator
• Pressure Regulation: Reduces refrigerant pressure for effective cooling
• Temperature Stability: Helps maintain consistent cabin temperature
• A/C Efficiency: Supports optimal operation of the air conditioning system
Expansion valves can wear or become clogged with debris over time. When the valve fails, refrigerant pressure may not be regulated correctly, leading to poor cooling performance or fluctuating cabin temperatures. Replacing a faulty expansion valve restores proper refrigerant flow and helps maintain efficient air conditioning operation.
When to Replace. Consider replacing the expansion valve if you notice:
• Weak or inconsistent air conditioning cooling
• Refrigerant pressure imbalance in the system
• A/C system repair requiring evaporator removal
• During air conditioning system overhaul or service

Information
Air con expansion valve.
OE Match expansion valve is a replacement for the original Porsche part, designed for Porsche 928, 964 and 993 models. It regulates the flow of refrigerant into the evaporator, ensuring the correct pressure balance for efficient cooling and reliable performance.
Fits:
Porsche 928 1982-95 M570 / M573
Porsche 964 1989-94 M573
Porsche 993 1995-98 M573
* M570 - Cars with air conditioner with improved efficiency
* M573 - Cars with standard air conditioner
Diagram ref no 35
What this product does:
• Controls refrigerant flow between condenser and evaporator
• Maintains stable pressure for consistent cabin cooling
• Prevents evaporator freeze-up and reduces compressor strain
Location: Installed in the A/C system, between the condenser and evaporator
A worn or clogged expansion valve can cause weak cooling, fluctuating cabin temperatures, or excess strain on the compressor. Replacing expansion valve restores proper cooling efficiency, protects the A/C system, and ensures long-lasting comfort in your Porsche.
