Kia Niro: Air Conditioning System / Receiver-Drier Repair procedures

Remove the condenser.

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

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

Apply air conditioning compressor oil along the O-rings and threads of the new bottom cap.

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.

Install a new bottom cap to the condenser.

• 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 to avoid leakage. • Be careful not to damage the radiator and condenser fins when installing the condenser. • Charge the system, and test its performance.
