Kia Niro: Air Conditioning System / Condenser Repair procedures

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.

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

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

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.

Disconnect the negative (-) battery terminal.

Remove the front bumper.

(Refer to Body - "Front Bumper Cover")

Remove the active air flap.

(Engine mechanical system - see "Active Air Flap (AAF)")

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

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

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

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

Install in the reverse order of removal.

• 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 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 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.
