What kind of refrigerant does a 2018 Honda CRV take?
The 2018 Honda CR‑V uses R-134a refrigerant for its air-conditioning system. This is the standard specification for most US-market CR‑Vs of that year, but you should verify the exact refrigerant on the vehicle’s under-hood service label for your specific VIN and market.
Refrigerant type for the 2018 CR‑V
In most 2018 CR‑V models sold in the United States and many other regions, the A/C system is designed for R-134a refrigerant. The correct refrigerant and the required lubricant (usually PAG oil) are detailed on the vehicle’s service label located near the A/C compressor or receiver/drier. Do not mix refrigerants, and never charge a system with an incorrect gas, as that can cause damage and reduce cooling efficiency.
Regional variations can occur. Some international markets or specific production runs have used different refrigerants in recent years, including R-1234yf. Always confirm the exact specification for your vehicle by checking the under-hood label, consulting the owner's manual, or contacting a Honda dealer with your VIN.
For any A/C work, prioritize proper recovery, leak checks, and correct recharging with the designated refrigerant and oil. A licensed automotive technician is best equipped to handle this safely and in compliance with environmental regulations.
Regional variations
While R-134a is typical for the 2018 CR‑V in many regions, some markets have migrated to R-1234yf for newer models. The Honda service label or dealership confirmation will provide the definitive answer for your exact vehicle and market.
How to confirm the refrigerant on your vehicle
To ensure you use the correct refrigerant, follow these steps:
- Check the under-hood A/C service label near the refrigerant ports for the exact specification (R-134a or R-1234yf).
- Consult the owner’s manual or contact a Honda dealer with your VIN to confirm the factory-recommended refrigerant.
- Have any A/C work performed by a certified technician who can safely recover existing refrigerant and charge the system with the proper oil and refrigerant.
These checks help prevent cross-contamination and ensure the system is charged correctly, maintaining cooling performance and protecting components.
Summary
For the 2018 Honda CR‑V, the typical refrigerant is R-134a. Always verify the exact specification on the vehicle’s service label or with a Honda dealer, as regional variations can exist. Do not mix refrigerants, and rely on a trained technician for any recovery, leak check, and recharging procedure.
