The block-style design uses captured O-ring connections, with suction inlet and outlet sized at No. 12 and liquid inlet and outlet sized at No. 6 and No. 10. It is specified for R134A refrigerant and front-position HVAC systems, making it a practical OE-style replacement for Toyota and Lexus vehicles that require this configuration. This part number 39343 also cross-references UAC EX10328C for the same application.\u003c\/p\u003e\u003ch2\u003eVehicle Fitment\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFits 2013-2020 Lexus LX570, front.\u003c\/li\u003e\n\u003cli\u003eFits 2008-2011 Lexus LX570, front.\u003c\/li\u003e\n\u003cli\u003eFits 2018-2020 Toyota Land Cruiser, front, w\/o Cool Box.\u003c\/li\u003e\n\u003cli\u003eFits 2013-2017 Toyota Land Cruiser, front.\u003c\/li\u003e\n\u003cli\u003eFits 2008-2011 Toyota Land Cruiser, front.\u003c\/li\u003e\n\u003cli\u003eFits 2009-2019 Toyota Sequoia, front.\u003c\/li\u003e\n\u003cli\u003eFits 2011-2016 Toyota Sienna, front.\u003c\/li\u003e\n\u003cli\u003eFits 2013-2018 Toyota Yaris, N\/A.\u003c\/li\u003e\n\u003cli\u003eFits 2016-2018 Toyota Yaris R, N\/A.\u003c\/li\u003e\n\u003cli\u003eFits 2011-2014 Lexus GX460, front, compatible with vehicles equipped with Dual Zone A\/C.\u003c\/li\u003e\n\u003cli\u003eFits 2011 Lexus GX460, front.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon Repair Uses\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRestores refrigerant metering in a weak or inconsistent A\/C system\u003c\/li\u003e\n\u003cli\u003eAddresses poor cabin cooling in Lexus LX570 and Toyota Land Cruiser applications\u003c\/li\u003e\n\u003cli\u003eHelps correct A\/C performance issues caused by a worn or restricted expansion valve\u003c\/li\u003e\n\u003cli\u003eSupports repair of front HVAC cooling complaints in Toyota Sequoia and Toyota Sienna models\u003c\/li\u003e\n\u003cli\u003eProvides the correct service part for R134A systems using a block-type valve\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eVerify refrigerant type, port style, and mounting location before installation. This valve uses female O-ring connections and captured O-ring sealing surfaces, so the mating lines and seals must match the vehicle’s original HVAC layout. Confirm the vehicle’s front A\/C configuration and, for 2011-2014 Lexus GX460 applications, Dual Zone A\/C equipment before ordering. Proper evacuation, leak checking, and system recharge are required after replacement.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eFour Seasons lists this expansion valve as meeting or exceeding OEM requirements, making it a specification-based replacement for factory-style HVAC service.
