Global Parts A/C Expansion Valve for Cadillac CT4 and CT5

Global Parts Part Number 3412054 is an A/C expansion valve for select Cadillac CT4 and Cadillac CT5 applications from 2020-2025. It regulates refrigerant flow before the evaporator so the system can use cooling capacity efficiently.

Key Features

• Expansion valve/orifice tube design for HVAC refrigerant control
• Helps meter refrigerant before the evaporator
• Fits 2020-2025 Cadillac CT4, N/A
• Fits 2020-2025 Cadillac CT5, N/A
• Global Parts Part Number 3412054

Product Details

This A/C expansion valve is built for vehicles that use a flow restrictor at the evaporator inlet. By slowing refrigerant before it enters the evaporator, the valve helps the system extract cooling more effectively. Global Parts recommends replacing the expansion valve or orifice tube whenever the A/C system is serviced, which makes this part a practical choice for maintenance on Cadillac CT4 and Cadillac CT5 models.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Uses

• Weak cabin cooling on Cadillac CT4 or Cadillac CT5
• Restricted refrigerant flow in the A/C circuit
• Service work after compressor, condenser, or evaporator repairs
• Restoring proper refrigerant metering at the evaporator
• Replacing a worn A/C expansion valve during HVAC maintenance

Installation Notes

Verify the vehicle’s A/C system design before installation and match the replacement to the original flow restrictor style. Replace the valve during system service, evacuate and recharge the refrigerant properly, and inspect seals and related components for wear before returning the system to service.

Quality Assurance

Global Parts supplies HVAC service components for direct-fit replacement applications. Part Number 3412054 is listed for confirmed Cadillac CT4 and Cadillac CT5 fitment from 2020-2025.
