The 2011 Honda CR-V uses R-134a refrigerant. It does not use the older R-12 or the newer R-1234yf. The system is designed for R-134a with a PAG oil lubricant; exact charge can vary by market and production date, so always verify with the vehicle’s service label or manual.
Refrigerant type and lubrication
The car's air conditioning system is designed for R-134a refrigerant. This has been the standard refrigerant for most vehicles manufactured from the late 1990s onward. The lubricant used with R-134a in Hondas is PAG oil (polyalkylene glycol), commonly PAG 46, though you should confirm the exact grade from Honda's service literature. Never mix PAG oil with mineral oil or other oil types, and avoid converting the system without proper procedure.
Oil compatibility
If you’re retrofitting from R-12 to R-134a, a full evacuation, rinse, and oil change are typically required, followed by proper charging with the specified oil fraction. Always use the recommended oil type and viscosity to protect the compressor.
System capacity and recharge guidelines
Before charging or recharging, note these general specs to guide safe service:
- Refrigerant type: R-134a
- Lubricant: PAG oil (commonly PAG 46)
- Typical system refrigerant capacity: about 20–23 ounces (approx. 567–651 grams) of R-134a; oil charge is specified by the service manual
- Do not use R-12 or R-1234yf in this model; ensure the system is evacuated before charging
Concluding: For the exact refrigerant and oil amounts, check the under-hood label or Honda service documentation, as variations exist by region and production date.
Service tips and safety
Use a dedicated R-134a recovery and recharge kit with a manifold gauge set to monitor high- and low-side pressures. Follow EPA refrigerant handling rules and wear eye protection. If the system shows signs of a leak or poor cooling, leak testing with UV dye and an electronic detector can help locate issues before refilling.
Summary
In short, the 2011 Honda CR-V requires R-134a refrigerant with PAG oil. Expect roughly a 20–23 oz refrigerant charge plus the appropriate oil, and always verify exact values on the vehicle’s service label or manual. For precise charging and service, consult a qualified automotive A/C technician.
