Using Komatsu WA320-5 Wheel Loader Radiator (Wide Core) (Fan Drive) Parts
Use the Komatsu WA320-5 Wheel Loader Radiator (Wide Core) (Fan Drive) Parts listing to identify aftermarket replacement parts within the c0 cooling system section. This wheel loader application is listed for machine serial WA320-5H50051 - UP; the diagram and parts table retain the selected configuration and its source notes.
The parts table contains 38 listed part occurrences, including radiator assembly (reference 419-03-H1180), radiator, oil (reference 419-03-H0P42) and radiator, water (reference 419-03-H0P43). Read any option and reference notes beside these entries before choosing a replacement; repeated references may represent separate positions in the source list.
When comparing cooling-system parts, check the engine designation and any fan, pump or connection options recorded in the selected diagram. A matching machine family alone does not establish the cooling arrangement.
Catalog quantities describe the illustrated assembly. Adjust the order quantity to what you need, select the relevant rows, and use Add selected to cart for verified store matches or Add selected to quote for quote items. The diagram alone does not establish current stock or part interchangeability.
