Detailed Description

Four Seasons 33602 is a steel filter drier for automotive A/C systems that helps protect the refrigerant circuit by trapping moisture and filtering contaminants.

This part cross-references Monroe Shocks & Struts 172992 for the same application.

Installation Notes and Tips

Replace the receiver drier whenever the A/C system has been opened for major service, compressor replacement, or leak repair.
