Hyundai Tucson: Condensor - Replacement

Hyundai Tucson - Fourth generation (NX4) - (2020-2023) - Workshop Manual / Heating, Ventilation and Air Conditioning (HVAC) / Air Conditioning System / Condensor - Replacement

  1. Remove the condensor.

    (Refer to Air conditioning System - "Condensor")

  2. Using a Lwrench, remove the cap (A) on the bottom of the receiver-drier.

  1. Remove the receiver-drier (A) from condenser using a long nose plier. Check for crumbled receiverdrier and clogged bottom cap filter.

  1. Install in the reverse order of removal.


  • Always replace the receiver-drier 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 or R-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.


The A/C Pressure Transducer (APT) converts the pressure value of high pressure line into voltage value after measuring it. By converted voltage value, engine ECU controls the cooling fan by operating it high speed or low speed. Engine ECU stops the operation of the compressor when the temperature of refrigerant line is very high or very low irregularly to optimize air conditioning system.
