Application and Buying Notes

Before buying, match the evaporator core against the vehicle application and the part number RD231810P. The listed fitment is specific to Western Star 4864 variants with the engine and date ranges shown, so it should not be assumed to suit other models or engine combinations.

Check the #8 MOR inlet and #10 MOR outlet against the existing air conditioning pipework, because the fitting sizes and the O ring to O ring arrangement need to line up for installation. The core is 310mm long, 257mm high, and 87mm deep, so physical clearance matters as much as the vehicle listing.

This is a tube and fin evaporator core with a stated weight of 3.84kg. That gives a useful reference when comparing replacement units, but it is still best practice to compare the old core, the fittings, and the vehicle details before fitting.

If the vehicle uses a different dash layout, hose arrangement, or evaporator housing, confirm compatibility carefully before purchase. Climate control components are best ordered by part number and application details rather than by appearance alone, especially where the fitting sizes are specific like #8 MOR and #10 MOR.

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 RD231810P 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.

Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a air conditioning evaporator core in workshop, fleet, trade, agricultural, or construction service, the listed electrical specification should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include WESTERN STAR 2800, WESTERN STAR 2800 2015, WESTERN STAR 4700, WESTERN STAR 4700 2013. 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.
