Product Number: 10123012
The Highway Automotive 10123012 is a direct-replacement radiator for Komatsu D155-series heavy construction machinery, catalogued under reference KM2014. Engineered to restore cooling system performance in demanding site conditions, this unit is built to serve as an OE-equivalent replacement for original-equipment radiators across the D155A, D155AX, and D155AXR model range.
Constructed from aluminium-to-aluminium (A/A) core material, this radiator delivers robust thermal transfer suited to the load cycles typical of dozer and earthmoving applications. The all-aluminium construction resists corrosion and maintains structural integrity under the vibration and thermal cycling inherent to construction plant operation.
The unit measures 1133 mm high × 392 mm wide × 126 mm deep, providing a precise dimensional fit for the D155-series installation bay. Cross-referencing against original-equipment numbers 17710811000A, 17A0341111, and 17A0341112 (3 OE references in total) allows straightforward identification against existing machine documentation and procurement records.
As the D155 series spans multiple build variants and production periods, buyers should verify fitment against their specific machine serial number and model suffix before ordering. The selection widget and OE reverse-lookup tool in the catalogue can confirm application to individual units.
Supplied as a single radiator assembly. Manufacturing origin is stated in the product trust information. No warranty terms are published in the current source data for this part.
