Global Parts A/C Expansion Valve for Sentra

Global Parts part number 3411398 is an A/C expansion valve for select 2000-2002 Nissan Sentra applications. It regulates refrigerant flow before the evaporator so the system can use cooling capacity more effectively.

• Fits 2000-2002 Nissan Sentra, N/A
• Global Parts 3411398 replacement for A/C flow restrictor service
• Paraphrases OE-style refrigerant metering function for evaporator performance
• Cross-references UAC EX529447C for the same application

How It Works

The expansion valve meters refrigerant entering the evaporator, creating the pressure drop needed for proper heat absorption. On 2000-2002 Nissan Sentra models, this part number 3411398 is used in the HVAC refrigerant circuit to control flow at the evaporator inlet. This part cross-references UAC EX529447C for the same application.

Common A/C Problems

• Weak cabin cooling on a Nissan Sentra
• Irregular evaporator refrigerant flow
• Restricted A/C performance after system service
• Incorrect refrigerant metering at the evaporator

Installation Notes

Replace the expansion valve during A/C service when the system is opened or components are replaced. Verify the refrigerant circuit is clean, evacuate the system properly, and confirm the correct fitment for 2000-2002 Nissan Sentra before installation. Part number 3411398 should be matched to the vehicle application listed above.

Quality Assurance

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