A/C Expansion Valve for Lexus and Toyota

Global Parts 3411343 is an A/C expansion valve for select Lexus and Toyota applications. It meters refrigerant flow before the evaporator so the system can use cooling capacity more effectively. This part is a direct-fit service item for 1990-1992 Lexus LS400, 1992 Lexus SC400, and 1989-1992 Toyota Cressida applications.

• Controls refrigerant flow entering the evaporator
• Supports proper A/C system pressure regulation
• Fits 1990-1992 Lexus LS400, N/A
• Fits 1992 Lexus SC400, N/A
• Fits 1989-1992 Toyota Cressida, N/A

Product Details

Global Parts 3411343 is built for HVAC service where accurate refrigerant metering is required. By slowing refrigerant before it reaches the evaporator, the expansion valve helps the A/C system deliver consistent cooling performance. This part cross-references Four Seasons 39042 for the same application.

Common A/C Problems This Part Can Address

• Weak cabin cooling
• Erratic evaporator refrigerant flow
• Improper A/C pressure balance
• Reduced cooling output after system service
• Expansion valve wear in older Lexus LS400, Lexus SC400, and Toyota Cressida systems

Installation Notes

Replace the expansion valve during A/C service when the system is opened or contaminated. Verify the refrigerant circuit is clean, evacuate the system properly, and confirm correct operation after reassembly. Use the vehicle-specific fitment above to confirm application before ordering.

Quality Assurance

Global Parts recommends replacing the expansion valve/orifice tube each time the A/C system is serviced to help maintain proper system performance.
