Sanden Air Conditioning Compressor 12V Direct Mount SD7H15 CXS4548

The Sanden SD7H15 air conditioning compressor is a 12V direct mount unit with part number CXS4548 and body number 4548. It is listed with a 119mm clutch diameter, 8 groove pulley section, vertical special pad fitting type, and WH head code, so it is important to match the mounting and pulley details to the vehicle before ordering.

This compressor is specified for Sanden units and carries the original equipment number 4548. It has a steel armature, weighs 5.2kg, and is supplied with an oil capacity of 300ml using SP15 oil. The notes also identify internal thread pad pad fittings and HPRV, which are useful checkpoints when confirming a replacement.

Verified application data includes Freightliner Argosy 60 Series 14.0L from 01/2000 onward, Freightliner Columbia CL120 60 Series 14.0L from 01/2003 onward, and Western Star 4864 and 4964FX 60 Series applications across the dates listed below. Because compressor fitment can vary with mounting style, pulley layout, and head code, the part number and physical specifications should be checked carefully against the vehicle already fitted.

Application and Buying Notes

Before ordering, compare the existing compressor against the key identifiers on this unit: CXS4548, body number 4548, SD7H15 series, 12V voltage, and direct mount configuration. The 119mm clutch diameter, 8 groove pulley section, and vertical special pad fitting type are all critical physical checks because the same vehicle family can use different compressor arrangements.

The fitting notes also call out internal thread pad pad fittings and HPRV, so those details should be matched to the compressor currently installed. If the old unit has a different head code, mounting face, or pulley section, do not assume the replacement will line up just because the vehicle is in one of the listed model ranges.

The one year warranty applies to the part as supplied, but it does not replace the need to verify fitment first. If the vehicle is a Freightliner Argosy, Freightliner Columbia CL120, or one of the listed Western Star applications, use the application range together with the part number and mounting details to make a final check before purchase.

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 CXS4548 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.

For part number CXS4548, 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 COLUMBIA, FREIGHTLINER COLUMBIA 2004, FREIGHTLINER COLUMBIA 2005, FREIGHTLINER COLUMBIA 2006. 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 fitment using part number CXS4548, body number 4548, SD7H15 series, 12V voltage, direct mount style, 119mm clutch diameter, 8 groove pulley section, and the vehicle application details listed above before ordering.
