Removal and Installation: Notes

The electric powertrain components are located in this area. The electric powertrain is a high-voltage system. You must be familiar with the electric powertrain system before working on or around it. Make sure you have read the electric powertrain service precautions before doing repairs or service.

NOTE: 

• Make sure you review the A/C service tips and precautions before doing repairs or servicing.
• Although a numbered sequence is shown, the parts can be removed independently of each other.
• Review the A/C refrigerant oil replacement before doing repairs or service.
• Plug or cap the lines immediately after disconnecting them to avoid moisture and dust contamination.
• Apply compressor oil when installing O-rings.
• Install the parts in the reverse order of removal unless otherwise specified.

Note for Electric Heater Coolant Pump 

• Engine coolant will run out when the hoses are disconnected; drain it into a clean drip pan. Be sure not to let coolant spill on the auxiliary electrical parts or the painted surfaces. If any coolant spills, rinse it off immediately.
• Note the layout of the hoses.

Note for Electric A/C Compressor 

• The electric A/C compressor is a high-voltage system. The high voltage cables and their covers are identified by orange coloring. The safety labels are attached to high voltage and other related parts. You must be familiar with the electrical powertrain before working around it. Make sure you have read the Service Precautions in the electrical powertrain section before doing repairs or service.
• Wear insulated gloves and use insulated tools to protect you from electrical shock.

Note for Electric A/C Compressor Relief Valve 

• If the electric A/C compressor relief valve released refrigerant to the atmosphere, determine and correct the cause of the excessive system pressure, then replace the relief valve.
• Plug the opening to keep moisture and foreign material from entering the system, and the electric A/C compressor oil from running out.

Note for A/C Condenser 

• Be careful not to damage the radiator fins, the A/C condenser fins, and the receiver line when removing the A/C condenser.
