Most Honda Pilot models use R-134a refrigerant.
That said, some later or region-specific variants may use R-1234yf. Always verify the exact specification for your vehicle before service.
Current standard for Honda Pilot refrigerants
The Honda Pilot lineup has historically relied on the traditional R-134a refrigerant for its air conditioning systems. While R-1234yf is gaining traction in some newer vehicles and markets, it is not universally adopted across the Pilot family. Always confirm the exact refrigerant type for your specific model year and region.
- R-134a (HFC-134a) is the default refrigerant for most Honda Pilots in the United States and many other markets.
- R-1234yf is used in some newer or region-specific vehicles and is not a universal standard for all Pilot models; verify for your vehicle.
Understanding which refrigerant your Pilot uses helps ensure proper charging, lubrication, and system longevity.
How to verify the refrigerant type for your Honda Pilot
Use these steps to confirm the refrigerant type on your exact vehicle before any service or recharge.
- Check the under-hood label on the A/C system, near the service ports or compressor, which usually lists the refrigerant type and capacity.
- Inspect the service ports: blue ports typically indicate R-134a, while yellow ports are commonly associated with R-1234yf (though labels should be used for confirmation).
- Consult the owner’s manual or the official Honda service manual for your model year; refrigerant specifications are documented there.
- Contact a Honda dealer or a certified A/C technician with your Vehicle Identification Number (VIN) to confirm the exact refrigerant specification for your vehicle.
- If you’re unsure after checking labels, have a professional perform a quick diagnostic to determine the correct refrigerant type without opening the system.
Correctly identifying the refrigerant type protects the system’s lubrication, oil compatibility, and overall cooling performance.
What to do if you need a recharge
Always use the refrigerant specified for your Pilot. Do not mix refrigerants, as cross-contamination can reduce efficiency and cause damage. If your vehicle uses R-1234yf, ensure the technician uses the appropriate oil and recovery equipment rated for that refrigerant. For R-134a, standard PAG oils and equipment compatible with 134a are required. Refrigerant service should comply with local regulations and is typically performed by licensed technicians.
Summary
In short, the Honda Pilot most commonly uses R-134a refrigerant, with some late or region-specific models potentially using R-1234yf. Always verify the exact type for your vehicle via the under-hood label, the owner’s manual, or a Honda dealer to ensure proper service and avoid damage to the A/C system.
Can anyone buy 1234yf refrigerant?
Only EPA-certified technicians are allowed to purchase ozone-depleting substances (ODS) or non-ozone depleting substitutes used as refrigerants, with limited exceptions.

Does my car use R-134a or R-1234yf?
Cars built mid-1990s to roughly 2014–2017 almost always use R134a. Most 2017–present vehicles, especially Euro, hybrid and EV models, use R-1234yf. Some EVs use specialised refrigerant blends depending on the cooling system. Your car has a sticker under the bonnet that confirms its exact gas type.
Can I refill my car AC refrigerant myself?
It used to be that only professionals could recharge an AC system, but there are now kits available to do it on your own. What you'll need is: AC recharge kit with refrigerant (R-134a or R-1234yf, depending on your vehicle) Safety gloves and goggles.
