Global Parts 3411602 A/C Expansion Valve - Front

A/C Expansion Valve for Toyota and Lexus Applications

Global Parts 3411602 is an A/C expansion valve that regulates refrigerant flow before it enters the evaporator. By slowing refrigerant at this point in the system, it helps the evaporator use cooling capacity more effectively. This part is a direct-fit service component for select Toyota 4Runner, Lexus GX460, and Lexus LX570 applications.

Key Features

• Expansion valve for HVAC A/C flow control
• Helps meter refrigerant before the evaporator
• Fits 2015-2020 Toyota 4Runner
• Fits 2015-2020 Lexus GX460, including 2020 front applications
• Fits 2018-2019 Lexus LX570
• Global Parts part number 3411602

Detailed Description

Global Parts 3411602 is built for vehicles that use an expansion valve to manage refrigerant delivery into the evaporator. Proper refrigerant metering is important for stable vent temperatures and consistent A/C performance. This part cross-references Four Seasons 39547 for the same application. It also cross-references UAC EX10350C and EX10556C for select applications. Common fitment includes 2015-2020 Toyota 4Runner, 2015-2020 Lexus GX460, and 2018-2019 Lexus LX570.

What This Part Helps Address

• Weak or inconsistent cabin cooling
• Improper refrigerant flow into the evaporator
• A/C performance loss after system service
• Temperature fluctuation at the vents
• Service replacement for a worn expansion valve

Installation Notes and Tips

Verify the vehicle’s A/C system design and match the part to the exact application before installation. For 2020 Lexus GX460, this listing shows front fitment. For 2015-2020 Toyota 4Runner and 2018-2019 Lexus LX570, confirm the system configuration against the vehicle’s service information. When servicing the A/C system, inspect related components and follow proper evacuation, recharge, and leak-check procedures.

Quality Assurance

Global Parts recommends replacing the expansion valve or orifice tube whenever the A/C system is serviced. That guidance reflects the role this component plays in refrigerant control and overall system performance.
