Most 2017-model vehicles use R-1234yf refrigerant; a minority still use R-134a depending on the make and market.
In practice, the exact refrigerant for a specific car is determined by its original design and the regional regulations in place when it was built. This article explains the two main refrigerants used around 2017 and how to verify the type for your vehicle.
Two main refrigerants used in 2017 model-year vehicles
Before listing the common options, note that the following two refrigerants were the primary choices for cars around 2017:
- R-1234yf: The newer standard adopted by most new cars from the early 2010s onward due to lower global warming potential.
- R-134a: The older refrigerant with higher global warming potential, still used by some models, particularly older designs or certain markets.
For most 2017 vehicles, R-1234yf is the refrigerant you’ll encounter, but you should verify for your specific car using the recommended checks below.
How to confirm your vehicle's refrigerant type
To determine the exact refrigerant used in your car, follow these steps:
- Look for a label on the under-hood A/C components or on the service port covers that lists the refrigerant type and required oil.
- Consult the owner's manual or a factory service manual for the refrigerant specification.
- Use the vehicle identification number (VIN) to look up original equipment specifications via the manufacturer’s site or a trusted repair database.
- When servicing, rely on a licensed technician who uses the correct refrigerant and oil and avoids mixing different types.
If you plan to recharge or replace refrigerant, ensure the system is evacuated properly and charged to the correct capacity by a professional.
Safety and handling considerations
R-1234yf is classified as an A2L (mildly flammable) refrigerant, so technicians follow strict safety procedures during service. R-134a is non-flammable but still requires proper handling and disposal in line with environmental regulations. Always have a qualified technician handle A/C refrigerant work.
Summary
In short, most 2017 vehicles use R-1234yf, with some models still employing R-134a depending on the maker and market. To know the exact type for your car, check the under-hood labeling, consult the owner’s manual, or contact a dealership or licensed A/C technician. The industry trend since the mid-2010s has favored R-1234yf for new vehicles because of its lower environmental impact.
