Caterpillar Radiator Assembly/Cooler is built with a high-efficiency aluminum plate-fin structure, designed to meet the demanding cooling requirements of heavy-duty construction equipment，which integrated system combines engine water cooling, hydraulic oil cooling, and charge air cooling (intercooler) into one compact assembly, delivering stable and efficient heat dissipation during continuous and high-load operation.
Product Highlights
Engineered for Caterpillar radiator systems with high-efficiency heat dissipation
The above models are for reference only. CAT excavators may vary depending on configuration and working conditions. Custom radiator and oil cooler solutions can be developed based on technical drawings and application requirements.
CAT Excavator Radiator Overview
Our CAT excavator radiator and oil cooler solutions are designed for replacement applications across multiple Caterpillar excavator models. Aluminum plate-fin construction provides efficient heat dissipation, reliable structural strength, and stable cooling performance for construction, mining, and other heavy-duty operating environments.

Custom development is also available for special or discontinued applications based on drawings, samples, dimensions, and cooling requirements.
Standard replacement radiators may not always meet the requirements of discontinued CAT models, modified equipment, or special cooling applications. For these projects, we can develop custom CAT excavator radiator solutions based on drawings, samples, OE information, dimensions, and operating requirements.
Core size, thickness, fin structure, tube configuration, mounting points, and inlet/outlet positions can be adjusted to match the original installation space and required cooling performance.
Development from drawings, samples, or OE specifications
Custom core dimensions and thickness
Tube and fin structure adjustment
Customized inlet, outlet, and mounting layout
Prototype and sample development before production
Pressure and leak testing for design verification
Custom development is suitable for older CAT excavators, discontinued radiator models, equipment modifications, and applications where standard replacement parts cannot provide the required fit or cooling performance.
