The 2019 Ford Expedition uses R-1234yf refrigerant (HFO-1234yf), the modern freon specified for most new vehicles since the mid-2010s.
Overview of the refrigerant in the 2019 Expedition
Ford adopted R-1234yf for environmental and regulatory reasons. R-1234yf has a much lower global warming potential than the older R-134a and requires different service equipment and lubricants. For your specific vehicle, the exact refrigerant type is typically indicated on the under-hood label near the AC components or in the owner's manual. In a 2019 Expedition, the expected specification is R-1234yf.
How to verify the refrigerant in your Expedition
To confirm the refrigerant type in your exact vehicle, use these quick checks:
- Look for an under-hood label near the air conditioning service ports that lists the refrigerant (look for R-1234yf).
- Check the owner's manual or a Ford service bulletin for your VIN.
- Ask a certified automotive A/C technician to identify the refrigerant and perform any recharge or recovery with the correct gas.
Verifying the refrigerant type helps ensure proper service and prevents damage from using the wrong gas.
Service considerations for 1234yf systems
Because the 2019 Expedition uses 1234yf, service should be performed with equipment designed for this refrigerant and the appropriate lubricants. Do not mix 1234yf with older R-134a. Use a certified technician and ensure proper recovery, evacuation, and recharge. 1234yf systems typically use PAG oil (often PAG 46) and require leak testing with compatible tools and detectors.
- Use 1234yf-compatible refrigerant and oil as specified by Ford (often PAG 46).
- Use recovery/recycling equipment rated for 1234yf; avoid using R-134a equipment on this system.
- Avoid mixing refrigerants; if the wrong gas has been introduced, the system may need flushing or component replacement.
- Follow safety guidelines: 1234yf is classified as A2L (mildly flammable) and should be handled by trained technicians.
Adhering to these service considerations helps maintain cooling performance and safety for the Expedition’s A/C system.
Summary
In summary, the 2019 Ford Expedition uses R-1234yf refrigerant. Always verify the refrigerant on the under-hood label or in the manual, and have the system serviced with 1234yf-compatible equipment and lubricants by a trained technician. Using the wrong refrigerant can cause damage, reduced cooling efficiency, and warranty issues.
