Hyundai Ioniq: Air Conditioning System / Condenser. Repair procedures

Hyundai Ioniq (AE) 2017-2025 Service Manual / Heating, Ventilation and 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.

•	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")

4.	Loosen the mounting bolts, remove the radiator upper cover (A).

5.	After loosening the mounting bolts, remove the condenser (A).

To install, reverse the removal procedure.

•	If you're installing a new condenser, add refrigerant oil (POE OIL).

•	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 or 1234yf to avoid leakage.

•	Be careful not to damage the radiator and condenser fins when installing the condenser.

•	Charge the system, and test its performance.

•	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.
