Product Details

The Four Seasons Filter Drier product line is used in automotive air conditioning systems to help keep refrigerant clean and dry after service or component replacement. Part number 33988 uses a steel filter drier design with pad mount connectors, a replaceable desiccant not required, and no moisture indicator window or sight glass. It is a new receiver drier built to OEM-level dimensional and functional expectations for A/C service work.

This part cross-references Carlson 7585 for the same application. Four Seasons 33988 is a practical choice when replacing an A/C receiver drier on vehicles such as Honda Civic and Toyota Corolla platforms that use pad mount receiver drier hardware.

What It Helps Fix

• Moisture contamination in the A/C refrigerant circuit
• Debris buildup after compressor or condenser service
• Reduced cooling performance caused by a saturated desiccant
• System contamination from an aging or restricted receiver drier
• Leak concerns at worn pad mount sealing surfaces

Installation Notes

Verify pad mount fitment, inlet and outlet diameter, and overall body dimensions before installation. Replace seals as required during A/C service, evacuate the system properly, and recharge with the correct refrigerant and oil specification. Because this receiver drier does not include a service port, switch port, or fuse plug, confirm the vehicle’s original configuration matches the part before ordering. For fitment-based searches, this part is commonly referenced for Honda Civic and Toyota Corolla A/C receiver drier replacement applications.
