The short answer is: it depends on the model year. Most older Ford Explorers use R-134a refrigerant, while many newer Explorers use R-1234yf. The exact specification is printed on a service label under the hood or in the owner’s manual, so verify before servicing.
Model-year guidance: R-134a vs R-1234yf
To help you identify the typical refrigerant used by era, refer to the following quick reference. Keep in mind regional differences and optional equipment can affect the specification.
- Pre-2020 Ford Explorers: R-134a refrigerant is standard, using PAG oil in the system.
- 2020 and newer Ford Explorers: R-1234yf refrigerant is commonly used, with POE oil in the system. However, always check the label to be sure.
To avoid confusion, rely on the markings on the A/C service label found near the radiator support, fender, or hood latch. The label lists the exact refrigerant type and oil, and will be the authority for that vehicle.
How to confirm the exact refrigerant for your Explorer
Use these steps to verify the refrigerant type for your specific vehicle before any service work.
- Open the hood and locate the A/C service label on the radiator support, near the firewall, or on the underside of the hood. Read the refrigerant type printed on the label (R-134a or R-1234yf) along with the recommended oil.
- Refer to the owner’s manual or Ford service specifications for your model year; the documentation lists the required refrigerant and oil type.
- If you’re using a shop, show them the label and VIN to access the data specific to your vehicle; technicians will verify the refrigerant via the vehicle’s data plate.
- Inspect the service ports if you are experienced with A/C work; the service ports usually indicate the refrigerant type on caps or stamps, though this is not universal across all years.
Using the correct refrigerant protects the system from improper pressures and oil compatibility, reducing the risk of compressor damage and leaks.
Why the refrigerant type matters
What happens if the wrong freon is used
R-134a and R-1234yf are not interchangeable. Using the wrong refrigerant can cause improper lubrication, pressure imbalances, and potential component damage. Refrigerant oils differ as well; mixing oils can reduce lubrication efficiency and lead to seals failure. Always ensure you’re using the correct type and oil as specified on the vehicle’s service label.
Summary: For Ford Explorers, verify the refrigerant on the under-hood label to know whether the system uses R-134a or R-1234yf. In general, older models rely on R-134a, while newer models commonly use R-1234yf; when in doubt, consult the owner’s manual or a certified automotive technician.
