Fitment Notes
- Always match OEM reference number(s) and vehicle details before ordering. Verify VIN/engine.
Professional Fitment Required: Electronic, electrical, and electromechanical components require correct identification before installation. Compare the new unit to the removed unit and verify mounting orientation, terminal or connector type, pin count or terminal arrangement, voltage rating, polarity, and any pulley or bracket configuration where applicable. Incorrect installation, polarity reversal, water or moisture ingress, improper connector seating, or mismatched specifications can damage the component, related ECU systems, or cause persistent fault codes. Installation by a qualified, VAT-registered workshop with appropriate diagnostic equipment is recommended.
Returns Notice: Once an electronic, electrical, or electromechanical component has been fitted, plugged in, energised, or shows signs of installation, returns are limited to manufacturing defect only. Confirm part compatibility before opening sealed packaging.
