This vehicle uses HFC-134a (R-134a) refrigerant which does not contain chlorofluorocarbons. Pay attention to the following service items:

  • Do not mix refrigerants CFC-12 (R-12) and HFC-134a (R-134a). They are not compatible.
  • Use only the recommended polyalkyleneglycol (PAG) refrigerant oil (DENSO ND-OIL 8) designed for the R-134a compressor. Intermixing the recommended (PAG) refrigerant oil with any other refrigerant oil will result in compressor failure.
  • All A/C system parts (compressor discharge line suction line evaporator condenser receiver/dryer expansion valve O-rings for joints) are designed for refrigerant R-134a Do not exchange with R-12 parts
  • Use a halogen gas leak detector designed for refrigerant R-134a.
  • R-12 and R-134a refrigerant servicing equipment are not interchangeable. Use only a recovery/recycling/charging station that is U.L.-listed and is certified to meet the requirements of SAE J2210 to service R-134a air conditioning system.
  • Always recover the refrigerant R-134a with an approved recovery/recycling/charging station before disconnecting any A/C fitting.
