433-1675-385-7942 Radiator — Cat 312D2 312D2L

This radiator is a vital heat exchanger within the engine's cooling system, responsible for dissipating heat from the coolant. Manufactured to meet rigorous OEM quality standards, it offers superior thermal efficiency and durability compared to a worn or corroded unit. Operators may notice a consistent rise in engine temperature, steam from the engine bay, or a sweet smell of coolant if this radiator is failing.

Installation & Application Notes

Flush cooling system with distilled water before refilling. Use pre-mixed coolant — never plain water, which causes corrosion. Pressure-test system after any cooling repair. Check thermostat by immersing in hot water — should open at rated temperature.

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 initial symptom is often a consistent increase in engine coolant temperature, especially during heavy operation. If left unaddressed, this can lead to reduced engine performance and potential damage. A severely compromised radiator can result in rapid overheating and engine shutdown.

Installation Tip

Thoroughly flush the cooling system before installing the new radiator to remove any scale or debris. Ensure all hose connections are properly seated and secured to prevent leaks.

Service Note

Inspect the water pump and thermostat for proper operation when replacing the radiator, as these can also affect cooling system performance.
