Product Details

The Four Seasons Expansion Valve line focuses on refrigerant metering components that regulate liquid refrigerant flow into the evaporator. Part number 38883 uses a block-style design with female inlet and outlet connections, making it suitable for service on select Toyota, Lexus, Geo, and Mitsubishi A/C systems. If you are replacing a worn or restricted valve on a 1990-1993 Toyota 4Runner or a 1992-1993 Lexus ES300, this valve matches the listed application data and supports proper system operation.

This part cross-references Monroe Shocks & Struts (e.g., 182292) for the same application.
