The Highway Automotive 10123017 is a replacement radiator engineered for Komatsu HD785 construction machinery, designed to maintain optimal engine coolant temperatures under the demanding thermal loads typical of heavy plant operations.
Constructed to exacting dimensional standards, this radiator measures 1383 x 418 x 126 mm (H x W x D) with an aluminium/aluminium core matrix, combining effective heat dissipation with the durability required in construction environments. The all-aluminium construction offers a strong balance of thermal conductivity and resistance to the corrosive effects of modern coolant formulations.
This unit directly replaces OE reference 17710861011, giving plant engineers and fleet maintenance teams a straightforward cross-reference for procurement and inventory management. With a single verified application for the Komatsu HD785, fitment is precisely defined, reducing the risk of ordering errors on the workshop floor.
This radiator is a standalone replacement part. No replacement grommets or ancillary spare components are included in this listing. Country of manufacture is confirmed on the product technical specification sheet. Warranty details are published in the platform technical specifications for this SKU.
