Example series shown - confirm exact fit with our engineers using your machine model or old part.
How It Works
- Hot hydraulic or engine oil enters the radiator from the circuit.
- Oil flows through the bar and plate core, and heat transfers to the fins.
- A fan blows air across the fins, carrying the heat away.
- The cooled oil returns to the circuit at a safe working temperature.
Applications & Aftermarket
Heavy-duty replacement radiators are used on excavators, wheel loaders, bulldozers and other mining and construction machines. If your original radiator is worn or discontinued, our CAT excavator radiator replacement is a fast, cost-effective alternative to OEM parts, built to the original envelope and duty.
We also supply cooling for related machines: excavator coolers, hydraulic oil coolers for Komatsu excavators and plate-fin hydraulic oil coolers.
