A/C Refrigerant Oil
A/C Refrigerant Oil Replacement
WARNING: Using the wrong refrigerant oil increases the chance of electric shock or death.
- Use only SANDEN SE-10Y refrigerant oil when servicing the A/C system.
Required POE refrigerant oil: SANDEN SE-10Y
- P/N 38899-RCJ-A01: 120 mL (4 fl.oz)
- P/N 38899-RMX-A01: 50 mL (1 2/3 fl.oz)
The A/C compressor in this vehicle is powered by the IMA battery module, and this oil is required because it has unique electrical insulting qualities.
Adding refrigerant oil to the system
Add the recommended refrigerant oil to the suction port of the A/C compressor in the amount listed if you replace any of the mentioned parts.
- To avoid contamination, do not return the oil to the container once dispensed, and never mix it with other refrigerant oils.
- Use immediately after opening can and do not store any remaining oil. Electrical insulating properties degrade quickly due to moisture absorption.
- Do not spill the refrigerant oil on the vehicle; it may damage the paint; if it gets on the paint, wash it off immediately.
Repairs needed if the wrong refrigerant oil was added
Use only the required Polyol Ester (POE) refrigerant oil SANDEN SE-10Y designed for the R-134a compressor. Intermixing the recommended (POE) refrigerant oil with any other refrigerant oil will result in A/C compressor failure. Using the wrong refrigerant oil can also be a safety hazard.
If the wrong refrigerant oil was added, and the A/C system is operated, the following components must be replaced:
- A/C compressor
- A/C condenser
- A/C evaporator
- Receiver/dryer
- A/C system lines and hoses
If the A/C system was not operated, then only the A/C compressor needs to be replaced.
