387-4365 Water Tank Radiator Core — Cat D6T

This is a radiator core, the primary heat exchange component within the engine's cooling system. It is engineered to meet stringent OEM standards for efficient heat dissipation, ensuring optimal engine operating temperatures unlike a clogged or leaking core which compromises cooling capacity. Symptoms of a failing radiator core include visible coolant leaks, engine overheating, and a sweet smell of burning coolant.

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

Visible coolant leaks from the radiator assembly are the first sign of a failing core. If ignored, the coolant level will drop, leading to progressively worse engine overheating and reduced performance. Continued operation with a compromised cooling system can lead to severe engine damage.

Installation Tip

Ensure the mounting surfaces are clean and free of debris before installing the new radiator core to prevent leaks. Do not overtighten mounting bolts, as this can distort the core or damage the mounting brackets.

Service Note

Inspect and pressure test the radiator cap and check the condition of all coolant hoses and clamps when replacing the radiator core.
