Product Description

Universal Air RD11118KTC is a header and desiccant bag kit used in A/C receiver drier service to help maintain refrigerant system dryness. In HVAC systems, the desiccant element absorbs moisture that can contribute to corrosion, reduced cooling performance, and internal contamination. This kit is listed for Buick Encore, Chevrolet Spark, and Chevrolet Trax applications, including Chevrolet Trax models without High Output. If you are sourcing an A/C receiver drier / desiccant element kit for these vehicles, RD11118KTC provides a fitment-specific service part reference.

Common Service Issues

• Moisture contamination inside the A/C system
• Reduced cooling output from a saturated desiccant element
• Corrosion risk in refrigerant circuit components
• Service replacement needs after receiver drier maintenance
• Fitment lookup for Buick Encore, Chevrolet Spark, and Chevrolet Trax A/C repair

Installation Notes and Tips

Verify the vehicle’s exact year, model, and engine configuration before ordering, especially for Chevrolet Trax applications marked without High Output. Replace the desiccant element during A/C system service when the receiver drier has been opened to air or when moisture contamination is suspected. Follow OEM refrigerant handling and evacuation procedures, and confirm all sealing surfaces are clean before reassembly. This part number is RD11118KTC.
