The short answer is that it depends on the model year. Most newer Odysseys use R-1234yf, while older models used R-134a. Always verify on your vehicle’s label or in the owner's manual to be sure.
Refrigerant types by model year
To understand which refrigerant your Odyssey uses, consider the production date and model year. Here is a general guide:
- Pre-2017 Odysseys and many earlier model years: R-134a
- 2017 through the early 2020s Odysseys: R-1234yf
- Current, late-2020s Odysseys: R-1234yf
Note: The exact specification can vary by region and production date. The only reliable source is the under-hood A/C label or the official service manual for your vehicle.
How to verify the refrigerant on your vehicle
If you’re unsure which refrigerant your Odyssey uses, here are reliable steps to confirm it:
- Check the under-hood sticker near the A/C service ports. It lists the required refrigerant (R-134a or R-1234yf) and the oil type.
- Consult the owner’s manual or a Honda service bulletin for your exact year and trim; the manual often provides refrigerant specifications and oil grade (often PAG 46).
- Ask a certified automotive technician or your local Honda dealership to read the label or verify the system with proper service equipment.
If you cannot locate a label or the manual, assume that newer Odysseys use R-1234yf and older ones use R-134a, but do not perform a recharge without proper identification.
Where to find the refrigerant label
On most Honda models, the refrigerant label is affixed to the underside of the hood, near the radiator support, or on a side panel near the A/C lines. It lists the refrigerant type, oil type, and capacity. If you can’t locate it, contact a dealer or review the service manual for your exact year.
Summary
In brief, the Honda Odyssey’s refrigerant type is age- and model-year dependent. Newer Odysseys typically use R-1234yf, while older ones used R-134a. Always verify with the vehicle’s label or the official manual to ensure correct service and charging, since using the wrong refrigerant can harm the system and affect warranties.
