Detailed Description

Four Seasons 39468 is an A/C expansion valve for HVAC systems that require precise refrigerant flow control at the evaporator. Its block-type design, aluminum body, and R134A compatibility make it a practical replacement for service on 2011-2017 Chevrolet Caprice, 2014-2017 Chevrolet SS, and 2008-2009 Pontiac G8 applications.
