Denso Air Conditioning Compressor 12V Direct Mount CXD6409

This Denso air conditioning compressor is a 12V direct mount unit with a pad fitting type and a 7 groove pulley. It is identified by part number CXD6409 and is listed with a 100mm clutch diameter, which are the key checks to make before ordering any compressor replacement.

The compressor is noted with PAG 46 oil type and a 145ml oil capacity. It weighs 6.7kg and is supplied as a single each unit, so it is important to compare the mounting style, pulley configuration and oil requirements against the vehicle application before installation.

The listed application for this compressor is Mercedes-Benz ML300 W164 3.0L from 12/2009 to 03/2012. There is also fitment data showing Mercedes-Benz GL-Class, M-Class, R-Class and Viano references in the broader application set, so the part number and mounting details should still be matched carefully to the vehicle fitted component.

As with any A/C compressor replacement, the safest approach is to confirm the compressor type, direct mount arrangement, 12V electrical requirement and part number CXD6409 against the existing unit. That helps avoid issues with pulley alignment, clutch match-up and the wrong oil specification at installation.

Application and Buying Notes

Before ordering, match the part number CXD6409 and confirm the compressor on the vehicle is a 12V direct mount unit with a pad fitting and 7 groove pulley. Those details are the most useful checks when comparing a replacement compressor to the one already fitted.

Clutch diameter is another point worth checking, especially where the old compressor has worn or been replaced previously. This compressor is listed with a 100mm clutch diameter, so that measurement should be compared with the existing component before purchase.

The provided application information includes Mercedes-Benz ML300 W164 3.0L from 12/2009 to 03/2012. Broader fitment references also include Mercedes-Benz GL-Class, M-Class, R-Class and Viano in the application group, but the safest buying decision is still to confirm the exact vehicle details and the existing compressor identification.

A direct mount compressor is not the same as a universal replacement. Mounting points, pulley section, clutch size and electrical requirements all need to line up with the vehicle setup, especially on climate control components where a mismatch can lead to installation delays and extra labour.

If the original compressor has failed, it is sensible to check the full system condition before fitting the new unit. That includes looking at contamination, correct oil charge, and whether the replacement part number CXD6409 is the same as the removed compressor or the specified service replacement for the application.

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 CXD6409 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.

Denso Air Conditioning Compressor 12V Direct Mount. Part number CXD6409 should be checked first. Listed voltage is 12. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Pulley configuration is 7 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number CXD6409, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a air conditioning compressor in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include MERCEDES-BENZ GL-CLASS, MERCEDES-BENZ GL-CLASS 2006, MERCEDES-BENZ GL-CLASS 2007, MERCEDES-BENZ GL-CLASS 2008. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm compatibility using part number CXD6409, the 12V direct mount configuration, 7 groove pulley, 100mm clutch diameter, and the listed Mercedes-Benz application details before purchase or installation.
