Application Details

This A/C orifice tube is used in rear HVAC systems on 2005-2007 Ford Escape and 2005-2007 Mercury Mariner models. The system notes indicate an OEM inline filter 3441236 is present, so verify the vehicle’s A/C layout before service. This part cross-references Four Seasons 39037 for the same application.

Common Service Issues

• Restricted refrigerant flow at the evaporator inlet
• Weak rear A/C cooling performance
• Contamination found during A/C system service
• Incorrect refrigerant metering after component wear

Installation Notes

Replace the orifice tube during A/C service when the system is opened, then evacuate and recharge the system to specification. Inspect the inline filter and related A/C components for debris or blockage before reassembly. Confirm rear-system fitment for the Ford Escape or Mercury Mariner by year and configuration.

Quality Assurance

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