Detailed Description

Four Seasons 33483 is a steel filter drier designed for A/C receiver drier service on older Ford HVAC systems. Its desiccant media helps remove moisture from the refrigerant stream, while the inline filter design supports cleaner system operation by capturing debris before it can circulate through the compressor, condenser, or expansion device. With 3/8 inch barb inlet and outlet fittings, this part is built for the listed Ford applications that use this connection style.

This part number 33483 is listed across multiple interchange references and is used in fitments such as 1987-1993 Ford Bronco, 1987-1993 Ford F-150, 1987-1993 Ford F-250, 1987-1993 Ford F-350, 1987-1993 Ford Ranger, 1987-1992 Ford Mustang, and select 1987-1992 Ford Econoline models. It is also listed for 1987-1991 Ford F-200 and 1987-1990 Ford Bronco II applications.

This part cross-references Monroe Shocks & Struts (e.g., 172720) for the same application.

Common Problems This Part Can Address

• Moisture contamination in the A/C system
• Debris buildup that can restrict refrigerant flow
• Poor cooling performance caused by a saturated receiver drier
• Service replacement needs after compressor or system repair
• Fitment issues on Ford HVAC systems requiring 3/8 in. barb connections

Installation Notes and Tips

Replace the receiver drier whenever the A/C system has been opened for service, especially after compressor failure or major refrigerant loss. Verify the inlet and outlet connection style, switch port requirement, and overall dimensions before installation. The body measures 2.500 in. in diameter and 8.000 in. in length, so confirm available mounting space on the vehicle before beginning the repair.

For best results, evacuate and recharge the system according to factory service procedures after installation. Because this unit is listed without a mounting bracket, reuse or verify the vehicle’s existing mounting arrangement as needed.

Quality Assurance

Four Seasons 33483 is a new replacement part that meets or exceeds OEM requirements for the listed applications. The Four Seasons Filter Drier line is built for service-focused HVAC repairs where moisture control and refrigerant cleanliness are critical to system performance.
