Global Parts 3411877 A/C Expansion Valve

Global Parts 3411877 A/C Expansion Valve

Global Parts 3411877 is an A/C expansion valve for the refrigerant flow control side of the HVAC system. It slows refrigerant before the evaporator so the system can use cooling capacity more effectively. Compatible with 2004-2006 Pontiac GTO applications, this part number 3411877 is a direct-fit service component for the A/C flow restrictor location.

Key Features

• Expansion valve/orifice tube style A/C flow restrictor
• Helps regulate refrigerant entering the evaporator
• Supports efficient evaporator cooling performance
• Fits 2004-2006 Pontiac GTO
• Global Parts part number 3411877

Product Details

This A/C expansion valve is used in the HVAC refrigerant circuit to reduce refrigerant flow before it reaches the evaporator. By controlling that flow, the system can better absorb heat and maintain stable cabin cooling. Global Parts 3411877 is listed for 2004-2006 Pontiac GTO models and is a practical replacement when servicing the air conditioning system. This part cross-references Four Seasons 39299 for the same application.

Common A/C Issues It May Address

• Weak or inconsistent cabin cooling
• Restricted refrigerant flow at the evaporator inlet
• Improper A/C system performance after service
• Need for a replacement flow restrictor during HVAC repair

Installation Notes and Tips

Replace the expansion valve/orifice tube during A/C service when the system is opened. Verify the refrigerant circuit is clean before installation, and follow the vehicle service procedure for evacuation, recharge, and leak checking. Confirm the application matches 2004-2006 Pontiac GTO before ordering part number 3411877.

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 evaporator performance.
