265-3556 Water Radiator — Cat 320D

This water radiator is essential for the engine's cooling system, dissipating heat generated during combustion to maintain optimal operating temperatures. Constructed from durable materials and engineered to precise specifications, it offers efficient heat transfer and longevity superior to a radiator with clogged passages or leaks. Operators may notice the engine temperature gauge rising into the red zone, steam escaping, or a sweet smell of coolant when this radiator is failing.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The most immediate sign of radiator failure is the engine temperature gauge indicating overheating. This can be accompanied by visible coolant leaks or steam emanating from the front of the machine. If left unaddressed, severe overheating can lead to catastrophic engine damage, including warped cylinder heads and seized components.

Installation Tip

Ensure the radiator mounting points are clean and the brackets are not bent, as this can cause stress on the new radiator core. Properly connect all coolant hoses, ensuring clamps are tightened securely to prevent leaks.

Service Note

Inspect the water pump, thermostat, and all coolant hoses for leaks or wear when replacing the radiator.
