ELECTRIC COMPRESSOR
Removal and Installation
REMOVAL
1. Disconnect the high voltage electrical system. Refer to Precautions For High-Voltage System.
2. Discharge the refrigerant. Refer to Refrigeration System.
3. Remove the engine air cleaner front air duct. Refer to Service and Repair.
4. Remove the engine undercover.
5. Remove the front RH wheel and tire.
6. Remove the side cover from inside the front RH wheel well.
7. Disconnect the electric compressor inverter unit connector.
8. Disconnect the high voltage electric compressor inverter connector (1).
- The lock lever of the high voltage electric compressor inverter unit connector (1) must be moved from the locked position (A) to the unlocked position (B) before pulling up to disconnect the high voltage electric compressor inverter unit connector (1).
CAUTION:
Cap or wrap the connector with a suitable material such as vinyl tape to avoid the entry of any contaminants.
9. Remove the high voltage harness bracket from the electric compressor.
10. Disconnect the high-pressure flexible hose and low-pressure flexible hose from the electric compressor.
CAUTION:
Cap or wrap the joint of the hose with a suitable material such as vinyl tape to avoid the entry of any contaminants.
11. Remove the electric compressor bolts using power tools, then remove the electric compressor.
INSTALLATION
Installation is in the reverse order of removal.
- The lock lever of the high voltage electric compressor inverter unit connector (1) must be moved from the unlocked position (B) to the locked position (A) after connecting the high voltage electric compressor inverter unit connector (1) as shown. Check the high voltage electric compressor inverter unit connector (1) to make sure it is fully seated and locked securely.
CAUTION:
- Replace the O-ring of the low-pressure flexible hose and high-pressure flexible hose with new ones, then apply electric compressor oil to them for installation.
- Use only Electric Compressor Oil ND-OIL 11 for the electric compressor of the air conditioning system. Using other A/C oils may damage the A/C system as they may conduct electricity.
- Do not use florescent leak detection dye in the A/C system.
- After installation of electric compressor, check potential equalisation
- After charging the A/C refrigerant, check for leaks. Refer to Refrigeration System.
