Product Details and Specifications

• Solves issues with compressor noise or mechanical failure

Installation Notes and Tips

Ensure the correct refrigerant oil type (Poe hybrid oil) is used during installation, as this compressor does not come pre-filled with oil. Verify that the clutch and switch components are compatible and installed separately if required. Properly replace the included O-rings (24131 and 24622) to prevent leaks. The tangent mount design facilitates alignment but confirm mounting points on the Hyundai Ioniq before installation.
