What It Helps Fix
- Inconsistent cabin cooling caused by poor refrigerant metering
- Warm air from the vents when the A/C system is charged but not cooling correctly
- Evaporator performance issues related to a restricted or sticking expansion valve
- Pressure imbalance in the A/C circuit tied to valve flow control problems
- Service repairs on vehicles requiring a block-type R134A expansion valve
Installation Notes
Verify the suction and liquid fitting sizes, thread diameters, and sealing washer style before installation. This valve is specified without a solenoid and uses two mounting holes, so the replacement should match the original HVAC layout. Always evacuate and recharge the system according to the vehicle service procedure after replacing an A/C expansion valve. Fits 2006-2011 Honda Civic, front right.
