Condenser Repair procedures

Inspection

  1. Check the condenser fins for clogging and damage. Clean and blow compressed air on any clogged fins. Unfold any bent fins with 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.

Warning

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.

  1. Disconnect the negative (-) battery terminal.
  2. Remove the front bumper beam assembly.

    (Refer to Body - "Front Bumper Beam Assembly")

  3. Remove the active air flap.

    (Refer to Engine Mechanical System - "Active Air Flap (AAF)")

  4. Loosen the bolt and remove the coolant hose (A).

Tightening torque : 7.8 - 11.7 N*m (0.8 - 1.2 kgf*m, 5.7 - 8.6 lb*ft)

Warning

Warning

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

  1. Loosen the bolts and then separate the liquid line (A).

  1. Loosen the mounting bolts and remove the condenser (A).

  1. Install in the reverse order of removal.

Warning

  • When 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, 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.

Warning

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.

Receiver-Drier Repair procedures

Replacement

  1. Remove the condenser.
  2. Remove the cap (B) on the bottom of the condenser with an L wrench (A).

Tightening torque :

Tightening torque : 9.81 - 14.71 N*m (1.0 - 1.5 kgf*m, 7.2 - 10.8 lb*ft)

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

  1. Apply air conditioning compressor oil along the O-rings and threads of the new bottom cap.
  2. Insert a new receiver-drier into the receiver drier tank. The receiver-drier must be sealed in vacuum before it is exposed to air for use.
  3. Install a new bottom cap to the condenser.

Warning

  • 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, 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.
