Hyundai Ioniq (AE) 2017-2022 Service & Repair Manual / Heating, Ventilation and Air Conditioning / Air Conditioning System / Refrigerant Line. Repair procedures

Replacement
1.
If the compressor is marginally operable, run the engine at idle speed, and let the air conditioning work for a few minutes, then shut the engine off.
2.
Disconnect the negative (-) battery terminal.
3.
Recover the refrigerant with a recovery / 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.
4.
Remove the engine cover.
(Refer to Engine Mechanical System - "Engine Cover")
5.
Remove the engine mounting support bracket.
(Refer to Engine Mechanical System - "Engine Mounting")
6.
Remove the bolts and the expansion valve (A) from the evaporator core.
Tightening torque :
8.8 - 13.7 N.m (0.9 - 1.4 kgf.m, 6.5 - 10.1 Ib-ft)

7.
Remove the 2 nuts, and then disconnect the discharge line (A) and liquid line (B) from the condenser.
Tightening torque :
8.8 - 13.7 N.m ( 0.9 - 1.4 kgf.m, 6.5 - 10.1 Ib-ft)

8.
Disconnect the A/C pressure transducer connector (A).

9.
Remove the engine room under cover.
(Refer to Engine Mechanical System - "Engine Room Under Cover")
10.
Remove the bolts, then disconnect the suction line (A) and discharge line (B) from the compressor.
Tightening torque :
7.8 - 11.8 N.m (0.8 - 1.2 kgf.m, 5.8 - 8.7 Ib-ft)
   
•
Plug or cap the lines immediately after disconnecting them to avoid moisture and dust contamination.

11.
Loosen the bracket mounting bolt (B) from suction& liquid assembly (A).
Tightening torque :
7.8 - 11.8 N.m (0.8 - 1.2 kgf.m, 5.8 - 8.7 Ib-ft)
12.
Remove the refrigerant line assembly (A) to the upper of engine room.

13.
To install, reverse the removal procedure.
   
•
Plug or cap the lines immediately after disconnecting them to avoid moisture and dust contamination.
•
Tighten the bolt or nut joint to the specified torque.
•
Using a gas leak detector, check for refrigerant leakage.
•
Evacuate air in the refrigeration system and charge system with refrigerant.
Capacit y : 600 ± 25 g (21.2 ± 0.88 oz.)
   
•
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.
