Replacement
[Without Heat Pump]
1.
Remove the condenser, and then use an L wrench to remove the bottom cap (B) from the condenser.

Tightening torque :
9.8 ~ 14.9 N.m (1.0 ~ 1.5 kgf.m, 7.2 ~ 10.8 lb-ft)

2.
Remove the desiccant (A) from the condenser using a long nose plier. Check for crumbled desiccant and clogged bottom cap filter.

3.
Apply air conditioning compressor oil along the O-rings and threads of the new bottom cap.
4.
Insert a new desiccant into the receiver drier tank. The desiccant must be sealed in vacuum before it is exposed to air for use.
5.
Install the new bottom cap to the condenser.
   
Always replace the desiccant and bottom cap at the same time.
Replace the O-rings with new ones at each fitting, and apply a thin coat of refrigerant oil before installing them. Be sure to use the right O-rings for R-134a to avoid leakage.
Be careful not to damage the radiator and condenser fins when installing the condenser.
Be sure to install the lower mount cushions of condenser securely into the holes.
Charge the system, and test its performance.
[With Heat Pump]
   
Be sure to read and follow the “General Safety Information and Caution” before doing any work related with the high voltage system. Failure to follow the safety instructions may result in serious electrical injuries.
Be sure to shut off the high voltage before doing any work related with the high voltage system(Refer to "High Voltage Shut-off Procedure"). Failure to follow the safety instructions may result in serious electrical injuries.
1.
Recover the refrigerant with a recovery/ recycling/ charging station.
   
Do not use the same A/C recovery / charging station as conventional belt-driven compressors.
Since the electric compressor uses high-voltage, you should use POE oil which have high volumetric resistivity.
If PAG oil mixes into the POE oil of the system, dielectric breakdown may occur due to decreased volumetric resistivity and the A/C compressor may not work.
2.
Disconnect the negative (-) battery terminal.
3.
Shut off the high voltage circuit. (Refer to EV Battery System - "High Voltage Shut-off Procedure")
4.
Remove the front bumper cover.
(Refer to Body - "Front Bumper Cover")
5.
Remove the receiver-drier (A) after loosening the mounting bolts.

6.
Install in the reverse order of removal.
7.
Apply air conditioning compressor oil along the O-rings and threads of the new bottom cap.
8.
Insert a new desiccant into the receiver drier tank. The desiccant must be sealed in vacuum before it is exposed to air for use.
9.
Install the new bottom cap to the condenser.
   
Always replace the desiccant and bottom cap at the same time.
Replace the O-rings with new ones at each fitting, and apply a thin coat of refrigerant oil before installing them. Be sure to use the right O-rings for R-134a to avoid leakage.
Be careful not to damage the radiator and condenser fins when installing the condenser.
Be sure to install the lower mount cushions of condenser securely into the holes.
Charge the system, and test its performance.
    Condenser Repair procedures
    Inspection 1. Check the condenser fins for clogging and damage. If clogged, clean them with water, and blow them with compressed air. If bent, gently bend them using a screwdriver or pliers. ...
