Air Con Evaporator.Restore the rear cabin air-conditioning performance on your Porsche 928 with this genuine evaporator unit (Part # 928 570 211 00). Designed for vehicles with the “Improved Efficiency” A/C option (M570) from around 1985 onwards, this direct-fit part replaces the original rear evaporator core and ensures proper cooling, airflow and de-humidification for the rear passenger compartment.
NOTE: LAST 1 IN STOCK
Fits:
- Porsche 928S2 4.7L 1984-86
- Porsche 928S4 5.0L 1987-92
- Porsche 928GT 5.0L 1989-91
- Porsche 928GTS 5.4L 1992-95
Diagram Ref No 19
What This Product Does:
- The evaporator is the component in the A/C system where the refrigerant enters the unit as a low-pressure liquid and absorbs heat from the cabin air, thereby cooling and de-humidifying the air that blows out to the cabin.
- In the rear A/C system of the 928, the evaporator is mounted within the rear HVAC housing and cools the air blowing into the rear passenger compartment.
- A properly functioning evaporator ensures the rear A/C system will deliver cold air, maintain correct charges of refrigerant, and operate efficiently.
- Since the 928’s air conditioning is sometimes used for extended periods (especially in warmer climates), the evaporator must be free of corrosion/leaks, have clean fins, and maintain proper airflow.
Symptoms Of Wear, Failure Or Need For Replacement:
- The rear A/C is not blowing cold, or takes much longer than usual to cool.
- Ice or frost formation on the evaporator core or housing — indicating restricted airflow or super-cooling.
- Leaking refrigerant: a crack or corrosion in the evaporator can cause refrigerant loss, evidenced by reduced cooling, a hissing noise, or oily residue in the HVAC box.
- Poor airflow or musty smell: a clogged, corroded or leaking evaporator may reduce airflow to the rear seats or cause musty odours from mold/moisture accumulation.
- Uneven temperature between front and rear zones (if applicable) — the rear section may lag or not reach set temperature.
- On inspection: visible corrosion, damaged fins, or signs of leaks around the evaporator housing, especially with older vehicles.
Why Replacement Matters:
- A failing evaporator not only reduces comfort (especially for rear passengers), but can lead to higher operating costs, increased wear on the compressor (due to low refrigerant charge or restricted flow), and potential damage to other components (such as blower motors, seals).
- For the 928, which is now a classic car, maintaining a fully functional A/C system helps preserve vehicle value and usability — especially if the car is driven in warmer climates or used for touring.
- Replacing the evaporator ensures the system remains efficient, prevents recurring refrigerant leaks, avoids breakdowns, and ensures correct integration with the rest of the HVAC system (expansion valves, driers, hoses).

Product Information
Genuine OEM A/C expansion valve, it controls the flow of refrigerant into the evaporator, ensuring correct pressure balance and consistent cooling performance.
Fits:
Porsche 928 1986 - 1995 M570 / M573
Porsche 964 1989 - 1994 M573
Porsche 993 1995 - 1998 M573
* M570 - Cars with air conditioner with improved efficiency
* M573 - Cars with standard air conditioner
Diagram ref no 35
What this expansion valve does:
• Regulates refrigerant flow between the condenser and evaporator
• Maintains optimal pressure for steady and efficient cabin cooling
• Prevents evaporator freeze-up and helps protect the A/C compressor
Location: Installed in the A/C system, positioned between the condenser and the evaporator.
Over time, expansion valves can clog, stick, or wear out, leading to poor cooling, fluctuating cabin temperatures, or compressor strain. Replacing with a genuine Porsche 92857312305 valve restores factory-level cooling efficiency, system reliability, and passenger comfort.
