Application and Buying Notes

Before ordering, match the part number CXS4491 and confirm the compressor details against the vehicle’s existing setup. The important points here are the 12V electrical system, SD7H15 series, direct mount arrangement, vertical O-ring connection, and JD head code, as these must align with the vehicle application and existing air conditioning hardware.

The listed fitment covers specific Freightliner Argosy 60 Series, Century Class Coronado, and FL80/112/FLC112 applications with stated engine and date ranges. If your truck falls outside those engine sizes or build dates, do not rely on a visual match alone. The 132mm clutch diameter, AA pulley section, and 54.55mm gauge line are useful checkpoints when comparing to the original compressor.

The note for this compressor specifies O-rings to suit ORX008 and ORX010 and an oil type of SP15, with oil capacity listed at 300ml. That makes correct installation and preparation important, especially when replacing a failed unit. Confirm the system is set up for the same mounting style and connection type before fitting, and check that the replacement compressor matches the existing Sanden application requirements.

If the vehicle has had previous repairs, modifications, or non-standard parts fitted, compare the compressor mounting, hose connection style, and head code carefully. The presence or absence of a dust cover, the 9kg weight, and the one year warranty are listed product details, but they do not replace application verification. Use the part number and fitment range together to reduce the chance of ordering the wrong unit.

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 CXS4491 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 CXS4491, 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 CENTURY, FREIGHTLINER CENTURY 1988, FREIGHTLINER CENTURY 1999, FREIGHTLINER CENTURY 2000. 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.
