The 2017 Honda Civic uses refrigerant R-1234yf.
In the 2017 model year, Honda equipped the Civic with a low-GWP refrigerant, R-1234yf, replacing older R-134a in many new vehicles. This article explains what that means for owners and technicians and how to verify the correct refrigerant for your specific car.
Refrigerant type and basic compatibility
Key facts about the refrigerant used in the Civic's air conditioning system and how to verify it.
- Refrigerant type: R-1234yf (also known as HFO-1234yf)
- Lubricant: POE-based synthetic oil designed for 1234yf systems
- Compatibility: The 2017 Civic A/C system is designed for 1234yf and should not be charged with R-134a
- Service requirements: Recharging or repairs require 1234yf‑specific equipment and proper handling; do not attempt with non-certified tools
For best results, always verify the refrigerant type on your vehicle’s service label or in the official Honda service documentation for your exact VIN and market.
How to verify the refrigerant type on your car
Look for the service label located on the engine bay area or near the radiator support; the label will indicate refrigerant type (R-1234yf) and the recommended oil. If in doubt, consult the owner's manual or a Honda service center.
Servicing considerations
Important guidance about servicing and safety when dealing with 1234yf systems.
- DIY topping off is not recommended; use a certified A/C technician with 1234yf handling equipment
- Only use R-1234yf refrigerant and compatible oil to avoid damaging the A/C system
- Ensure the service equipment is certified for 1234yf and that recovery/recycling complies with environmental regulations
- Check the vehicle’s under-hood label to confirm refrigerant type before any service
Adhering to these guidelines helps ensure proper cooling performance and compliance with environmental and safety regulations.
Summary
The 2017 Honda Civic uses R-1234yf refrigerant in its air conditioning system, paired with POE oil and 1234yf‑compatible servicing equipment. Always confirm the refrigerant type via the under-hood label or owner’s manual and have A/C work performed by a qualified technician using the correct materials. This aligns with the industry-wide shift to low-GWP refrigerants for that model year.
