374-7491-9y-3318-2w-5541 Radiator Core — Cat 3406 3516

This radiator core is the primary heat exchange component of the engine's cooling system, responsible for dissipating heat from the coolant into the surrounding air. It is constructed to meet rigorous OEM performance specifications, ensuring efficient cooling and longevity, unlike a corroded or leaking core. Operators may notice the engine temperature gauge rising into the red zone, steam from the engine bay, or a significant loss of coolant when this part fails.

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 first sign of a failing radiator core is often a gradual increase in engine operating temperature, especially under load. If left unaddressed, this can lead to overheating, causing severe engine damage and potential coolant loss. Continued operation with a compromised radiator core risks catastrophic engine failure due to excessive heat.

Installation Tip

Ensure all mounting surfaces and sealing areas are clean and dry before installing the new radiator core to prevent leaks. Do not apply excessive force when connecting hoses, as this can damage the core's fittings.

Service Note

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