The 2016 Honda Pilot uses R-134a refrigerant (commonly called freon). It does not use the newer R-1234yf or the old R-12, and the system should be serviced with the specified refrigerant and lubricant only.
Refrigerant type and why it matters
Honda's service data for the 2016 Pilot specifies R-134a as the refrigerant, paired with PAG oil for lubrication. Using the wrong refrigerant can lead to poor cooling performance, compressor damage, and warranty issues. While the industry has shifted toward R-1234yf for many newer vehicles, the 2016 Pilot remains on R-134a.
Service implications
When servicing, a certified technician will recover the refrigerant, evacuate the system to a deep vacuum, check for leaks, replace the receiver-drier if the system has been opened, and recharge with the correct amount of R-134a and PAG oil. Do not mix refrigerants and avoid attempting a home refill without proper equipment and handling.
Practical guidance for owners
For a recharge or diagnosis, request R-134a refrigerant and the appropriate PAG oil. If your vehicle’s service history shows a different refrigerant, consult a Honda dealer or a qualified HVAC technician to verify compatibility before any recharge or repairs.
Summary
The 2016 Honda Pilot takes R-134a refrigerant. Use the correct PAG oil, avoid R-1234yf or R-12, and rely on a trained technician for charging, leak checks, and related maintenance to protect the system and its warranty.
What Freon is in a 2016 Honda Pilot?

2016 Honda Pilot R1234YF Refrigerant.
What kind of Freon does a 2016 Honda take?
R-134a refrigerant
The 2016-2020 Honda Civic (2- and 4-Door), 2017-2021 Honda Civic (Hatchback) and 2017-2021 Civic Type R cars. These Civics use R-1234yf refrigerant which is supposed to be more friendly to the environment than R-134a refrigerant.
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.
Does Honda use 1234yf?
The 2016 Pilot, Civic, and Fit EV are using R-1234yf. As new models are redesigned or introduced, they will have R-1234yf with POE oil. The POE oil that is required for these systems on Honda/Acura vehicles is not the same oil that is required for high-voltage vehicles (HV).
