Sanden Air Conditioning Compressor 12V Direct Mount SD7H15 CXS4492

This Sanden air conditioning compressor is a 12V, direct mount unit in the SD7H15 series, identified by part number CXS4492 and original equipment number 4492. It is supplied as a single unit and is listed with a one year warranty. The compressor uses a 125mm clutch diameter and a 6 groove pulley section, which are important checks when matching the drive setup on the vehicle.

The fitting type is horizontal tube O ring, and the note supplied with the unit specifies O rings to suit ORX016 x 2. The head code is MDA Head, and the gauge line is 54.97mm. These details matter when comparing the replacement to the existing compressor, especially where the hose connection style, pulley layout, or mounting arrangement needs to match exactly.

Known application detail is provided for Freightliner models fitted with the ISX 14.9L engine, including Freightliner Cascadia ISX 14.9L from 01/2004 onward, Century Class CST120 ISX 14.9L from 01/1999 onward, and Columbia CL120 ISX 14.9L from 01/1999 onward. As with any air conditioning compressor, the vehicle’s existing part number, mounting style, connector type, and pulley configuration should be checked before ordering.

Application and Buying Notes

Before ordering, compare the existing compressor against CXS4492 and confirm the vehicle uses a Sanden SD7H15 direct mount layout with a 12V electrical setup. The 125mm clutch diameter, 6 groove pulley section, and horizontal tube O ring connection are all practical match points that can rule a part in or out quickly.

If you are replacing a failed compressor, inspect the line connections and mounting pattern on the vehicle before purchase. The listed note calls for O rings to suit ORX016 x 2, so the sealing arrangement should be checked at the same time as the hose type and head code. Small differences in connection style or pulley configuration can affect whether the part will fit correctly.

The supplied application details cover specific Freightliner models with ISX 14.9L engines, including Cascadia, Century Class CST120, and Columbia CL120. If the vehicle is not one of those applications, rely on the part number, mounting style, voltage, and connector details rather than assuming compatibility from appearance alone.

A compressor should always be matched carefully to the vehicle’s existing component, especially where the system has already been modified or repaired. Confirm the original equipment number 4492, the direct mount format, and the 54.97mm gauge line measurement before fitting. That approach reduces the risk of ordering a compressor that looks similar but does not suit the installation.

This compressor is supplied as each and carries a one year warranty, which is useful to know when planning the repair, but it does not replace the need to verify fitment first. Air conditioning components are sensitive to incorrect application, so checking the vehicle details, part number, and connection style is the best way to avoid unnecessary downtime.

Where possible, compare the old unit’s label, clutch dimensions, pulley grooves, and hose end style against the listed specifications. If the existing compressor is missing or unreadable, the model application and the part number CXS4492 become even more important for identification. Taking these checks seriously helps ensure the replacement aligns with the vehicle’s system requirements.

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 CXS4492 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.
