What type of refrigerant does a 2015 Subaru WRX take?
The 2015 Subaru WRX uses R-134a refrigerant (HFC-134a).
In practical terms, this model year relies on the traditional R-134a refrigerant rather than the newer R-1234yf. The system requires the appropriate PAG oil and should be serviced by a qualified technician to ensure correct lubrication, pressures, and oil charge. Mixing refrigerants or incorrect oil can damage seals and reduce cooling performance.
Confirming the refrigerant type for your vehicle
To be certain about your specific car, verify the information on the under-hood service label, consult the owner's manual, or check Subaru’s official service documentation. These sources will confirm the exact refrigerant type, oil specification, and charging guidance for your car’s A/C system.
Key facts about R-134a in the 2015 WRX
- Type: R-134a (HFC-134a).
- Oil compatibility: Typically PAG oil is used with R-134a in Subaru systems; ensure the correct oil type when recharging.
- Not compatible with R-1234yf; do not mix refrigerants or retrofit without proper procedures.
- Service requirements: The system should be evacuated and recharged using the proper equipment and procedures by a trained technician.
Note that exact oil quantity and charge amount can vary by model variant and configuration. Always rely on the manufacturer’s specifications or a professional technician for precise guidance.
Tips for servicing
When planning a recharge or replacement, follow these steps: verify the refrigerant type on the vehicle’s label, use the correct PAG oil for R-134a, and have the system evacuated and recharged with proper equipment. Do not substitute R-1234yf or other refrigerants without professional assessment.
Where to verify for your car
Check the under-hood A/C label, the owner's manual, or Subaru’s service documentation for the exact refrigerant type, oil specification, and capacity. If unsure, contact a licensed automotive HVAC technician.
Summary
