The above models and dimensions are for reference only. KOMATSU equipment may vary depending on configuration and working conditions. Custom radiator and oil cooler solutions can be developed based on technical drawings and application requirements.
Our KOMATSU excavator oil coolers and radiator solutions are designed for replacement applications across PC, PW, and other heavy equipment series. Aluminum plate-fin construction provides efficient heat dissipation and reliable cooling performance for hydraulic and engine cooling systems used in construction, mining, and earthmoving applications.
| Product Type | KOMATSU Excavator Radiator / Hydraulic Oil Cooler |
|---|---|
| Material | Aluminum |
| Core Structure | Aluminum plate-fin core |
| Cooling Medium | Hydraulic oil / Engine coolant, depending on model |
| Applicable Equipment | KOMATSU excavators and construction machinery |
| Model Matching | Based on KOMATSU model, OE number, and core dimensions |
| Core Dimensions | Model-specific; refer to the compatible model table above |
| Customization | Core size, thickness, fin structure, tube configuration, and connections can be customized |
We support replacement requirements for KOMATSU excavator radiators and hydraulic oil coolers based on equipment model, OE number, core dimensions, and installation requirements. Suitable replacement options can be matched for different KOMATSU excavator series to help reduce sourcing and fitment errors.
For older, discontinued, or non-standard models, replacement products can also be developed from drawings, samples, dimensions, or confirmed technical specifications.
For discontinued KOMATSU models, modified equipment, or applications where standard replacement parts do not match the original cooling system, custom radiator and hydraulic oil cooler development is available based on drawings, samples, OE information, or confirmed dimensions.
Core height, width, thickness, tube arrangement, fin structure, mounting points, and inlet or outlet positions can be adjusted according to the available installation space and cooling requirements of the equipment.
Custom development is suitable for older KOMATSU excavators, discontinued radiator or oil cooler models, equipment modifications, and other applications where standard replacement products cannot provide the required fit or cooling performance.
