Application and Buying Notes

When checking whether CXD2378 is the right compressor, start with the physical match: 12V operation, direct mount configuration, MOR - Pad fitting type, 8 groove pulley, and 164mm clutch diameter. If any of those do not match the existing unit or the vehicle setup, the compressor may not be suitable without further verification.

The listed applications cover Freightliner Coronado 114 with Detroit DD15 14.8L from 01/2010 onwards, plus several Western Star 4864 variants with Detroit DD13 12.8L, DD15 14.8L, ISX 14.9L, C12 380HP 12.0L, and 365HP 14.1L engine combinations. Matching the engine designation and date range is important, but it should still be confirmed against the existing compressor and mounting arrangement before purchase.

This unit is specified for Denso units and uses PAG46 oil, with an oil capacity of 170ml. The note also calls for O rings to suit CPX4005 x 2, so these associated parts should be checked as part of the replacement process rather than assumed to be included with the compressor.

The compressor is supplied without a dust cover and weighs 8kg, which may help when comparing the replacement to the removed part and checking freight handling expectations. For workshop use, it is wise to compare the old compressor label, port arrangement, and belt drive details with the listed CXD2378 specification before fitting.

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 CXD2378 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.
