Denso Air Conditioning Compressor 12V Direct Mount 10S15C CXD6378

This Denso air conditioning compressor is a 12V unit in the 10S15C series, supplied as a direct mount compressor with a pad fitting type. It is identified by part number CXD6378 and is listed with an 8 groove pulley section, a 164mm clutch diameter, and a weight of 8kg.

It is intended for vehicle air conditioning applications where the compressor mounting, pulley layout, and electrical system all match the vehicle requirements. The listed application notes include Freightliner Coronado 14.8TD DD15 from 1/2010 onward, and Western Star 4800 models with 10.3L, 12.7L, 12.8L, 14.0L, 14.9L and 15.2L engines from 1987 onward.

For buyers comparing replacements, the most important identifiers here are the Denso brand, 12V operating voltage, 10S15C series, direct mount construction, and CXD6378 part number. These details help narrow the match before checking the vehicle’s existing compressor, mounting arrangement, and belt pulley alignment.

Application and Buying Notes

Before ordering, compare the existing compressor against the key identifiers on this unit: Denso 10S15C, 12V, direct mount, pad fitting, 8 groove pulley, and 164mm clutch diameter. These details matter because compressors that look similar can differ in mounting pattern, pulley style, or clutch size, and those differences affect whether the unit will physically fit and line up correctly.

The application notes point to Freightliner Coronado 14.8TD DD15 from 1/2010 onward and Western Star 4800 models with the listed engine sizes from 1987 onward. That is useful guidance, but the safest check is still the vehicle’s original compressor part number and configuration, especially if the truck has had previous repairs, engine swaps, or air conditioning modifications.

A direct mount, pad-style compressor should be matched carefully to the bracket and hose arrangement already on the vehicle. The listed 8 groove pulley section must also suit the belt setup in the vehicle, and the 12V electrical system must match the compressor specification. If any of those points differ, the part may not be the correct replacement even if the vehicle model appears close.

The 8kg weight can also be a practical reference when handling the part or comparing it to the removed compressor. If you are checking compatibility in the workshop, confirm the compressor series, mounting face, clutch diameter, and part number CXD6378 before final installation. That reduces the risk of ordering the wrong unit and then having the vehicle apart waiting on another compressor.

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 CXD6378 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 10S15C. Part number CXD6378 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 8 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number CXD6378, 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 FREIGHTLINER CORONADO, FREIGHTLINER CORONADO 2010, WESTERN STAR 4800, WESTERN STAR 4800 1994, WESTERN STAR 4800 1995, WESTERN STAR 4800 1996. 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.

Compatibility note: Please confirm fitment by matching part number CXD6378, Denso 10S15C series, 12V specification, direct mount pad fitting, 8 groove pulley, and the vehicle application details before purchasing. When in doubt, compare the removed compressor and the vehicle build information rather than relying on appearance alone.
