Installation Notes and Tips

Verify the OE number 1665000049 and confirm the vehicle’s reservoir style, cap, and sensor configuration before installation. This part number V30-8405 is listed for Mercedes-Benz GLE350, GLE400, GLE43 AMG, GLE550, GLE550e, GLE63 AMG, GLS450, GL450, and related applications, so matching the exact model year and cooling-system layout is important.
