What It Helps Fix

• Inconsistent cabin cooling on Volvo R1234YF A/C systems
• Restricted or uneven refrigerant metering at the evaporator
• Warm air from the vents caused by a failing expansion valve
• Pressure imbalance in the HVAC refrigerant circuit
• A/C performance loss after system service or component replacement

Installation Notes

Verify refrigerant type, port size, and system layout before installation. This valve uses O-ring connections and does not include mounting hardware. Replace O-rings as needed, evacuate and recharge the system to specification, and confirm proper superheat and vent temperature after service.
