In most Ram 1500 models, the refrigerant type depends on the model year: older trucks typically use R-134a, while newer ones generally use R-1234yf. Always verify on the vehicle’s label or in the owner's manual for your specific truck.
Model-year guide to refrigerant types
Below is a concise guide by generation/year to help you identify which refrigerant your Ram 1500 uses. Regional variations exist, and the definitive source is the under-hood service label or the VIN-specific documentation.
- 2009–2018 Dodge Ram 1500: R-134a refrigerant.
- 2019–present Dodge Ram 1500: R-1234yf refrigerant.
- Exceptions: Some regional markets or special-purpose fleets may differ; always check the under-hood label or the owner's manual for your exact vehicle.
Understanding the refrigerant type helps with maintenance planning, service procedures, and proper recycling or disposal. If your Ram 1500 is not easily identifiable by year, consult a dealer or a certified A/C technician who can confirm using the vehicle identification number (VIN) and the service label.
How to confirm for your Ram 1500
To verify the refrigerant in your particular truck, look for the official labeling and use trusted service resources. The following steps outline a typical verification process.
- Locate the under-hood service label on the radiator support or near the A/C components; it lists the refrigerant type (R-134a or R-1234yf) and charging specifications.
- Check the owner’s manual or the original window sticker/build sheet for the model year’s refrigerant specification.
- When servicing, use the correct refrigerant and oil, and have a qualified technician evacuate and recharge the system to the manufacturer’s specifications.
Incorrectly charging or mixing refrigerants can damage the system and violate environmental regulations. If in doubt, rely on a dealership or a licensed A/C service shop for confirmation and service.
Differences between R-134a and R-1234yf
R-134a has been a long-running standard in many vehicles but carries a higher global warming potential (GWP) than R-1234yf. R-1234yf offers a much lower GWP and is used in newer vehicles, including many recent Ram 1500 models. While both refrigerants serve the same function, they require different oils, charging equipment, and recovery procedures. Always use the refrigerant specified for your truck to ensure proper cooling performance and compliance with environmental regulations.
Summary
For the Dodge Ram 1500, refrigerant usage is year-dependent: R-134a for 2009–2018 models and R-1234yf for 2019–present models. Regional variations and specific trims may alter this, so always verify with the under-hood label or official documentation. When in doubt, consult a certified technician to ensure the correct refrigerant, oil, and charging procedure are used.
