A/C Refrigerant Oil Replacement

A/C Refrigerant Oil Replacement

Special Tools Required

- Oil Injector Tool Robinair ROB16256, commercially available
*

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.

It is important to have the correct amount of refrigerant oil in the A/C system to ensure proper lubrication of the A/C compressor. Too little oil damages the compressor; too much oil reduces the cooling capacity of the system, and can produce high vent temperatures.

NOTE:

- To avoid contamination, do not return the oil to the container once dispensed, and never mix it with other refrigerant oils.
- Use the refrigerant oil immediately after opening the container, and dispose of any unused oil. The oil rapidly absorbs moistures, which damages its electrical insulating properties.
- Do not spill the refrigerant oil on the vehicle; it may damage the paint; if it gets on the paint, wash it off immediately.

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 following parts.










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 (PAG or mineral oil, for example) will result in A/C compressor failure. Using the wrong refrigerant oil can also be a safety hazard Technician Safety Information.

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.
