Application and Buying Notes

The most useful identifiers for this compressor are the part no. CXN0003, OEM number H12A1AE4DC, and the physical specifications: 12V, direct mount, 8 groove pulley, 124mm clutch diameter, and pad fitting type. Those details must match the vehicle’s existing compressor and air conditioning setup, not just the make and model name.

The listing notes suitability for Mazda 3 BK 2.0 Diesel from 2009 onward, and also references Mazda 3 and Mazda 6 model groups in the fitment data. Even so, air conditioning compressors can differ by engine, bracket arrangement, pulley configuration, and fitting style, so the safest approach is to compare the old unit and vehicle details side by side before buying.

The compressor is specified for Panasonic unit make applications and suits standard O ring fittings. That means the connection style is a practical check point during replacement, especially where the original compressor has been swapped before or where the vehicle has had prior air conditioning work.

Oil capacity is listed at 120ml, and that is a useful technical reference when assessing the part, but correct installation and system preparation still depend on the vehicle’s exact air conditioning setup. If the existing compressor, pulley, or fittings differ from these specifications, the part should be rechecked before fitting.

This unit carries a two year warranty, which is helpful from a parts supply point of view, but warranty cover does not replace fitment verification. Confirm the vehicle application, the mounting style, the groove count, and the compressor face type before finalising the order.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number CXN0003 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.
