The expansion valve for the A/C (air-conditioning) system, designed to regulate refrigerant flow into the evaporator core. Positioned between the condenser and evaporator, it drops refrigerant pressure and allows the refrigerant to expand - thus enabling effective cooling.
Fits:
Porsche 970.1 Panamera 2010 - 2013
Porsche 970.2 Panamera 2014 - 2016
Diagram ref no 3
• Position on Vehicle: Located in the A/C refrigerant line, typically near the evaporator housing inside the HVAC unit or just downstream of the condenser, depending on model variant.
• Cross-Reference / Alternative Numbers: OEM part number: 970 573 621 00 (Sometimes printed as 970-573-621-00)
• Applications: Replacement valve for faulty or failing expansion valves in the A/C system — often necessary when cooling efficiency drops, or when other major A/C components are being replaced, to ensure the whole system operates correctly.
The expansion valve plays a critical role in the A/C system by controlling refrigerant flow and pressure drop into the evaporator. If the valve becomes clogged, sticky, or malfunctions, the result can be reduced cooling performance, erratic temperature control, or even damage to other A/C components. Replacing a worn or failing valve restores correct refrigerant metering, improves cabin comfort, and extends the life of the A/C system.
When and why to replace:
• A/C blowing warm air despite compressor and condenser functioning.
• Symptoms of frost build-up or long cooling times indicating restricted refrigerant flow.
• After replacement of condenser, evaporator or compressor - fitting a new expansion valve ensures the system is fully refreshed.
• Visible leaks or corrosion around the valve body or refrigerant line.
• When the vehicle has high mileage or original A/C components that may be nearing end-of-life.

OEMatch Heating / Air conditioning Housings — Fit, Function, Confidence
Heating and air conditioning housings form the main structure of a Porsche’s HVAC system, locating and sealing the blower, evaporator and heater core while directing airflow. Replacing a damaged housing restores balanced airflow and reduces noise, helping to maintain consistent cabin comfort and reliable climate control for Porsche models.
Available Types- Blower motor housings
- Evaporator housings
- Heater core housings
- Air distribution boxes
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original heating / air conditioning housings.
OE (Original Equipment) refers to parts matching original specifications for the heating / air conditioning housings and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM heating / air conditioning housings engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
OEMatch provides a wide range of Porsche components and maintains a large parts catalogue; the range includes thousands of individual part numbers and several thousand reference cross-references, with new product lines under development to support restoration and repair needs.
- Restores correct airflow and system balance for reliable cabin temperature control
- Prevents air leaks and loss of heating or cooling efficiency
- Reduces cabin noise and vibration by securing HVAC components
- Cracking or warping of plastic due to repeated heat cycles
- Damaged mounting points or degraded seals that permit air leaks
- Corrosion around metal fasteners and debris buildup restricting airflow
A correctly fitted housing restores the structural integrity of the HVAC assembly and ensures internal components operate within intended tolerances. This reduces stress on blower motors and heater cores, prevents air loss through leaks, and supports consistent climate control across a range of Porsche models, from classic cars to modern vehicles.
Advantages- Constructed from heat-resistant materials for long-term durability
- Designed to manage airflow and sealing to original specifications
- Suitable for restorations and climate-system rebuilds where reliable fit and function are required
