Kia Optima Hybrid: Air Conditioning System / Condenser Repair procedures

Kia Optima Hybrid (TF HEV) 2016-2020 Service Manual / Heating,Ventilation, Air Conditioning / Air Conditioning System / 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.

2.	Check the condenser connections for leakage, and repair or replace it, if required.

Replacement

Recover the refrigerant with a recovery/ recycling/ charging station.

1)	Do not use the same A/C recovery / charging station as conventional belt-driven compressors.

2)	Since the electric compressor uses high-voltage, you should use PVE oil which have high Volumetric Resistivity.

3)	If the PVE or POE oil of the system gets mixed 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.

Remove the discharge line and liquid line (A) from the condenser.

Tightening torque :

3.9~5.8 N.m(0.4~0.6Kgf.m, 2.9~4.3 Ib-ft)

Plug or cap the lines immediately after disconnecting them to avoid moisture and dust contamination.

4.	Disconnect the mounting clip, and then remove the air duct hose assembly (A).

5.	Loosen the radiator bracket mounting bolts (A).

6.	Remove the radiator fan. (Refer to EM group - “Radiator”)

7.	Disconnect the pin (A) and then remove the condenser (C) from radiator (B).

Install in the reverse order of removal, and note these items :

–	If you''re installing a new condenser, add refrigerant oil ND-OIL8.

–	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.
