Common Repair Symptoms

• Weak or inconsistent cabin cooling
• Incorrect evaporator refrigerant metering
• A/C pressure irregularities
• Leak points at the valve connections
• Reduced system efficiency after HVAC service

Installation Notes

Verify refrigerant type before installation; this valve is specified for R134A systems. Confirm inlet and outlet dimensions against the original part: inlet 1 is 35.3 mm, inlet 2 is 25.6 mm, outlet 1 is 15.5 mm, and outlet 2 is 18.3 mm. Replace sealing components as needed and follow proper evacuation and recharge procedures after service.

Quality Assurance

Nissens manufactures this expansion valve to OE-matching standards and subjects it to testing for pressure performance, tightness, opening behavior, set-point setting, and internal finish.
