Global Parts 3411970 A/C Expansion Valve

Global Parts 3411970 A/C Expansion Valve

Global Parts 3411970 is an A/C expansion valve for vehicle air conditioning systems that meters refrigerant flow before it enters the evaporator. By reducing refrigerant pressure and controlling flow, it helps the evaporator absorb heat efficiently for stable cabin cooling.

How It Works

This expansion valve is used in the HVAC refrigerant circuit to regulate how much refrigerant reaches the evaporator. Proper metering supports consistent cooling performance in vehicles such as the Cadillac XT4, Chevrolet Malibu, Buick Envision, and Buick LaCrosse. Part number 3411970 is a direct-fit service part for the listed applications, and it also cross-references UAC EX10578C for the same application.

Common Problems It Can Address

• Weak or inconsistent A/C vent temperatures
• Refrigerant flow restriction at the evaporator inlet
• Cooling performance loss caused by a worn metering valve
• Erratic evaporator operation in the HVAC system
• Service replacement for a failed expansion valve in the A/C circuit

Installation Notes

Verify the vehicle year, make, and model before ordering. This part is listed for N/A position applications, so confirm the original valve style and refrigerant line configuration during service. Inspect the surrounding A/C components, including the evaporator, lines, and seals, before reassembly to help prevent repeat repairs.

Quality Assurance

Global Parts supplies HVAC service components for replacement use in listed vehicle applications. Part number 3411970 is built for the specified fitments and is intended to restore proper refrigerant metering in the A/C system.
