•
If the POE oil of the system gets mixed with PAG oil, then dielectric breakdown due to decreased volumetric resistivity can occur and inoperative A/C compressor may result, A/C compressor may not work.
2.
Disconnect the negative (-) battery terminal.
3.
Remove the front bumper.
(Refer to Body - "Front Bumper Cover")
