Using Komatsu WA380Z-6 Thermostat (#26580638-) (Aec00-001001) Parts
Use the Komatsu WA380Z-6 Thermostat (#26580638-) (Aec00-001001) Parts listing to identify aftermarket replacement parts within the engine cooling system section. This wheel loader application is listed for machine serial 66847-UP; the diagram and parts table retain the selected configuration and its source notes.
The parts table contains 4 listed part occurrences, including thermostat assembly (reference 6754-61-6212), thermostat assembly (reference 6754-61-6211) and thermostat (reference 5292739). Read any option and reference notes beside these entries before choosing a replacement; repeated references may represent separate positions in the source list.
The source engine application is SAA6D107E-1L (engine serial 26580638-UP). Match that engine identification as well as the machine serial range; the general machine model is not a substitute for engine-specific applicability.
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.
