The Highway Automotive 10123006 is a direct-fit radiator designed for Komatsu construction plant machinery, specifically the Komatsu WA450 wheel loader. Built to restore cooling system performance in demanding site environments, this radiator is identified under OE reference 17710931000 and is verified against Komatsu original-equipment specifications.
Constructed from aluminium/aluminium (A/A) materials throughout, the unit delivers reliable thermal management suited to the high-load duty cycles typical of heavy construction equipment. The all-aluminium construction supports efficient heat dissipation whilst keeping the assembly weight appropriate for the WA450 application.
The radiator measures 1033 mm high × 423 mm wide × 101 mm deep, providing the precise dimensional envelope required for a correctly seated fitment. These dimensions correspond directly to the original-equipment specification for the WA450, ensuring correct hose alignment and mounting without modification.
This replacement is backed by the PartsForMachines Fit Guarantee. The OE cross-reference 17710931000 is verified against manufacturer data, so buyers can order with confidence. The listing covers one application in total — the Komatsu WA450 in the construction field — and no additional fitment variants are recorded in the current data set.
