Handling Compressor Oil
- Use only the following specified compressor oil for this vehicle. Using compressor oil (PAG oil) other than specified compressor oil can damage the A/C compressor.
- Do not spill compressor oil on the vehicle. A drop of compressor oil on the vehicle surface can eat away at the paint. If compressor oil gets on the vehicle, wipe it off immediately.
- Compressor oil (PAG oil) has a higher moisture absorption efficiency than the previously used mineral oil. If moisture mixes with the compressor oil, the refrigerant system could be damaged. Therefore, install caps immediately after using the compressor oil or removing refrigerant system parts to prevent moisture absorption.
- If the refrigerant gas is completely discharged from the system for reasons such as a malfunction during A/C operation, repair or replace the malfunctioning part, charge the refrigerant to the specified amount and always add 60 ml {60 cc, 2.0 fl oz} of compressor oil. If the compressor oil is not adequately replenished, the A/C compressor may quickly deteriorate, abnormal noise may develop, cooling performance may be affected or, in the worst case, the A/C compressor may seize.
