Global Parts 3411862 A/C Expansion Valve

A/C Expansion Valve for Toyota Tacoma and Chevrolet SSR

Global Parts 3411862 is an A/C expansion valve block that meters refrigerant flow before it enters the evaporator. By controlling refrigerant pressure at this point in the system, it helps the evaporator absorb heat efficiently in Toyota Tacoma and Chevrolet SSR applications.

• Type: Exp Valve Block 3/8 x 3/4 x 3/4 x 3/4
• Fits 2005-2021 Toyota Tacoma
• Fits 2003-2006 Chevrolet SSR
• OE-style A/C flow restrictor for service replacement
• Global Parts part number 3411862

How This Expansion Valve Works

The expansion valve/orifice tube is a critical A/C flow restrictor that reduces refrigerant pressure before the evaporator. That pressure drop allows the refrigerant to absorb heat more effectively, which supports proper cooling performance in the HVAC system. Global Parts 3411862 is built for direct replacement service on Tacoma and SSR platforms, and the part number 3411862 cross-references DENSO Auto Parts 475-2066 for the same application.

Common Problems It Can Address

• Weak or inconsistent cabin cooling
• Incorrect refrigerant metering at the evaporator
• A/C performance loss after system service
• Restricted refrigerant flow caused by a worn valve
• HVAC system inefficiency in Toyota Tacoma or Chevrolet SSR models

Installation Notes and Tips

Replace the expansion valve/orifice tube during A/C service when the system has been opened or contaminated. Verify the block style and port dimensions match the original unit before installation. After replacement, evacuate and recharge the system according to factory service procedures for the specific Toyota Tacoma or Chevrolet SSR application.

Quality Assurance

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