Sanden Air Conditioning Compressor 12V Direct Mount SD7H15SHD Part No. CXS4075

The Sanden Air Conditioning Compressor is a 12V direct mount unit in the SD7H15 series, identified by part number CXS4075. It is listed with a 119mm clutch diameter and an 8 groove pulley section, so those mounting and drive details should be checked against the vehicle before purchase.

This compressor is described as a Freightliner application from 2007 onward, and the supplied fitment data also references Freightliner Century, Columbia and Coronado as well as Sterling Trucks L-Line. Because those trucks can vary by build and cooling setup, the part number and compressor style should be matched carefully.

The unit is sold as each, carries a one year warranty, and sits within the cooling and AC components groups. For anyone replacing a truck air conditioning compressor, the direct mount format, 12V electrical specification and SD7H15 body number are the key identifiers to confirm alongside the existing unit.

Application and Buying Notes

When replacing a truck air conditioning compressor, the safest check is to compare the old unit against the listed identifiers: Sanden, SD7H15, direct mount, 12V, 119mm clutch diameter and 8 groove pulley section. Those details matter because compressors may look similar but differ in mounting pattern, clutch size and belt drive arrangement.

The fitment information provided points to Freightliner 2007 onward and also names Freightliner Century, Columbia and Coronado, plus Sterling Trucks L-Line. That is useful as a guide, but it should not replace a physical or part number match. If the existing compressor carries CXS4075 or a matching SD7H15 direct mount configuration, that is the strongest confirmation.

Before ordering, check the compressor mounting style, pulley groove count and clutch diameter on the vehicle currently fitted. A 12V compressor is only suitable where the electrical system and application are intended for that specification, and the warranty is one year on the supplied unit.

If the vehicle has had previous repairs, conversions or engine-side changes, do not rely on model name alone. The same truck range can use different AC component combinations, so the part number CXS4075 and the SD7H15 identification are the most reliable reference points in this listing.

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 CXS4075 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.

Compatibility note: Confirm fitment by matching part number CXS4075, SD7H15 direct mount configuration, 12V rating, 119mm clutch diameter and 8 groove pulley section against the existing compressor and vehicle application.
